Service Pack releases are cumulative and contain all previous Service Pack fixes and any new fixes created after Service Pack 3. IMPORTANT: SP4 contains only 40-bit encryption. This release isn't supported for installation on an existing North American 128-bit installation of Windows NT 4.0. If you install SP4 on a computer with 128- bit encryption, system services might fail to start. IMPORTANT: It's recommended that you stop running any critical services before you apply Windows NT 4.0 SP4. For more preinstallation recommendations, see section 2.1, "Before You Install the Service Pack." 1.1 What's New in Service Pack 4 --------------------------------- 1.1.1 Active Accessibility Support Microsoft Active Accessibility (MSAA) is a COM-based standard method by which a utility program interacts with an application's user interface (UI). Using MSAA applications can expose all UI elements and objects with standard properties and methods. SP4 includes five new application programming interfaces (APIs). These new APIs include: - GetGUIThreadInfo - GetAncestor - RealChildWindowsFromPoint - RealGetWindowClassA - RealGetWindowClassW 1.1.2 DCOM/HTTP Tunneling This update allows DCOM client/server communication to cross firewalls over the HTTP protocol port. The new protocol "Tunneling TCP" is used like other DCOM protocols. The new moniker type OBJREF is passed in HTML to the client. The benefits of Tunneling TCP include high performance, use of existing open ports in the firewall, and control of client access for proxy administrators. For more information, see http://www.microsoft.com/com. For instructions on installing Tunneling TCP, see section 3.11, "Installing COM Internet Services" under User Notes. 1.1.3 Euro Key Patch The Euro Key Patch is an update to include the new European "euro" currency symbol. The update supplies the core fonts (Arial, Courier New, and Times New Roman) and the keyboard drivers. 1.1.4 InternetGroup Management Protocol (IGMP) v2 IGMPv2 allows a computer to inform the router that it's leaving a group. This update enables the router to determine if there are no more members in a group and then executes a command to stop forwarding mcast packets on to the link. This update is useful when users are frequently joining and leaving groups. 1.1.5 Microsoft File and Print Service for NetWare (FPNW) Support for Client32 Microsoft File and Print Services for NetWare permits the Windows NT 4.0 Server to act as a NetWare 3.X Server and is able to process file and print requests from NetWare clients without changing or updating the NetWare client software. This Service Pack provides an update that allows Windows NT 4.0 to support NetWare's Client32. This update installs only on those computers that have the FPNW service already installed. 1.1.6 Proquota.exe The Proquota.exe is a utility that can be set up to monitor the size of users' profiles. If an individual user's profile exceeds the predetermined file limit, the user won't be able to log off of the computer until the user reduces the size of the file. 1.1.7 Remote Winsock (DNS/Port 53) Proxies or firewalls will often disable the Domain Name System (DNS) port number 53 in order to deter external sites from querying the internal DNS structure. As a result, inbound response packets sent on port 53 can't be received. SP4 provides a solution to change the Windows NT DNS server port number and configure it to use a different port number when connecting outbound. To enable this feature, a registry value "DWORD" is created. Locate \services\dns\parameters\SendOnNonDnsPort and set to a non-zero value to go off port 53. If the value is < 1024 the server can use any port number. If the value is > 1024 the server will use the port number specified. 1.1.8 Remote Procedure Calls (RPC) Enhancements for Visual Basic (VB) RPC enhancements for VB have been provided in this release. In VB, a "User Data Type (UDT)" is added allowing the TypeLib arrangement of structures. These new user interfaces, IRecordInfo, provide UDT information and a UDT field for the Access Database. 1.1.9 Routing Information Protocol (RIP) Listener If you utilize RIP Listener on a computer running Windows NT 4.0, you can use SP4 to update this component. If you want to install RIP Listener after you apply SP4, use the following procedure. To install the RIP Listener: 1. Insert the SP4 CD into the disc drive, and change the folder to \I386 (or \Alpha). 2. Copy Oemnsvir.wks to D:\<winntsystemroot>\system32\oemnsvir.inf. 3. Click Start, point to Settings, and click Control Panel. Double- click Network, and on the Services tab, click Add. 4. In Network Service, select RIP for Internet Protocol, and then click OK. 5. In the Windows NT Setup dialog box, type the path for the location of the SP4 files and click OK. 1.1.10 Visual Studio-MICS This Service Pack includes an update to Visual Studio called Visual Studio Analyzer Events. Visual Studio Analyzer Events provides a graphical representation of high-level behaviors and their solutions. Use Visual Studio Analyzer Events to view graphically simple tables of event logs, the system's performance, and Windows NT Performance Monitor (NT PerfMon), as well as other system data. 1.1.11 Year 2000 (Y2K) Fixes This Service Pack contains fixes for known Year 2000 issues for Windows NT 4.0, including: - The User Manager and User Manager for Domains recognize the year 2000 as a leap year. - The Date/Time Control Panel applet can update the system clock. - Find Files supports only numeric character recognition in the decades field. - Word document properties recognize both 1900 and 2000 as valid centuries and support four-digit years. - The Dynamic Host Configuration Protocol (DHCP) administrators program supports displaying the years between 2000-2009 with a minimum of two digits. For more information, see section 2.4, "Year 2000 Service Pack Installation." 1.1.12 Compaq Fiber Storage Driver This driver and .Inf are located in the \Drvlib folder. When installed, the Compaq fiber storage driver along with the .Inf provides support for Compaq fiber storage devices. The certified devices are: - Compaq Fiber Channel Host Controller/P for PCI. - Compaq Fiber Channel Host Controller/E for EISA. 1.1.13 Internet Explorer 4.01 Service Pack 1 Internet Explorer 4.01 Service Pack 1 is located in SP4 in the \Msie401 folder. Run Ie4setup.exe to install this version of Internet Explorer on your computer. 1.1.14 Message Queue (MSMQ) for Windows 95 Client This Service Pack also includes MSMQ Windows 95 Client fixes, located in the \Support\Msmq.95 folder. Most problems that are mentioned in section 3.10, "Message Queue (MSMQ) Notes," also apply to Windows 95. In addition, the Windows 95 MSMQ update fixes a problem causing long delays with MQOpenQueue() and MQIS operations on offline computers. This MSMQ Windows 95 update doesn't have an uninstall option. 1.1.15 Option Pack Fixes This Service Pack release includes Option Pack fixes and enhancements. If you have the Internet Information Server version 4.0 Option Pack installed, the Service Pack 4 update program will automatically update the Option Pack components installed on your computer. When beginning the installation of the Windows NT Option Pack 4.0 on a server with Windows NT SP 4.0 and Internet Information Server 3.0, the following message may appear: "Setup detected that Windows NT 4.0 SP4 or greater is installed on your machine. We haven't tested this product on SP4. Do you wish to proceed?" The Windows NT Option Pack 4.0 is fully tested and supported to run on servers with the Windows NT Service Pack 4.0. Click Yes to continue Setup. NOTE: It?s recommended that you reinstall SP4 after you install Windows NT Option Pack 4.0. Otherwise, an MSMQ MQIS Controller installation won?t work until the Windows NT Service Pack 4.0 is reinstalled. 22.214.171.124 Certificate Server The Microsoft Certificate Server is a standards-based, highly customizable server application for managing the creation, issuance, and renewal of digital certificates. Certificate Server generates certificates in standard X.509 format. These certificates are used for a number of public-key security and authentication applications including, but not limited to, server and client authentication under the Secure Sockets Layer (SSL) protocol and secure e-mail using Secure/Multipurpose Internet Mail. The update to Certificate Server includes: - Teletex Encoding--Data encoded as teletex in a certificate request will be encoded as teletex data in the certificate issued. Formerly, this data would have been encoded as Unicode in the certificate issued. - Serial Number--Serial numbers are generated according to X.509 standards. These serial numbers are automatically generated, unique, and always positive. This is to accommodate restrictive mail clients. - Backup/Restore--Specific backup requests are supported, including backing up keys and certificates. - An update to the default policy module so that mail certificates issued are usable by Outlook 98. - An update to Certificate Server to fix a problem with certificates issued on February 29th of a leap year. Previously, the validity period would have the NotBefore and NotAfter dates set to the same date. With this update, NotBefore and NotAfter are now set correctly in the context of the CA validity for certificates issued on February 29th of a leap year. For information on how to use the keys and certificate backup/ restore utility, go to the Knowledge Base at http://support. microsoft.com/support/ and search for KB article Q185195. This release of Certificate Server doesn?t support certificate hierarchies. However, a limited subset of the functions of Certificate hierarchies work specifically with Exchange. You can get additional information on this from a white paper titled "Creating Certificate Hierarchies with Microsoft Certificate Server Version 1.0." This is available as a self- extracting .exe file (Hier3.exe) on the Microsoft Web site at http://support.microsoft.com/support/downloads/LNP279.asp. 126.96.36.199 Index Server Index Server is a content indexing engine that provides full text retrieval for Web sites. Index Server requires that Internet Information Server be installed. 188.8.131.52 Internet Information Server (IIS) The following Internet Information Server version 4.0 Option Pack components are installed on your computer: 1. Security Enhancements--Support for long file names for access restrictions on a file or a folder. 2. Performance--Improvements on the logging and caching of information. These improvements include, but aren't limited to: - IIS 4.0 performance on extension mapping. - IIS 4.0 memory performance for mapping log files. - IIS 4.0 performance in mapping unmapped data files if memory configuration is low or stressed. 184.108.40.206 Message Queue (MSMQ) for Windows NT This update to MSMQ includes: - Performs cleanup of unused message file space every six hours to reduce disk-space usage. NOTE: This schedule may be configured via the <MessageCleanupInterval> MSMQ registry key (in milliseconds). - Clears all obsolete express message files when the MSMQ service starts. - Enforces case insensitivity with foreign language characters in private queue names. - Reduces occurrences of duplicate messages in persistent delivery mode. - Exhibits performance counters for remote queues after a system recovery. - Correctly shows per-session outgoing messages performance counters. - MSMQ MQIS servers refresh cached information every 12 hours. - Fixes a problem causing transactional messages to be rejected in some cases. - Allows specifying external certificates via the MSMQ ActiveX components interface. - Transactional messages can be read from connector queues after restarting the MSMQ connector application. - MQSetQueueSecurity for private queue is supported. - MQCreateQueue for private queues now works on Windows NT Server 4.0 Option Pack installations on Microsoft Cluster Server computers. - Supports sending Microsoft PowerPoint and Microsoft Word documents using ActiveX components. - Fails when user attempts the renewal of internal certificates when Primary Enterprise Controller (PEC) is unreachable. - Machine quota limitation correctly recomputed after restarting the MSMQ service. - MSMQ COM objects correctly process asynchronous message arrival events in multithreaded applications. - Improved detection and reporting of corrupted message packets in message files that could have resulted in a hung MSMQ service previously. - Transactional messages sent offline are no longer rejected with a bad message class: MQMSG_CLASS_NACK_BAD_DST_Q. The symptom was that such messages were immediately routed to the sender's exact dead letter queue. - Supports sending messages to different computers that have the same IP address. This can happen when a server attempts to send messages to two different RAS clients that happen to be assigned the same address one after the other. - Recovers correctly when sending messages from a server to a client whose address is no longer valid (e.g., a RAS client that has timed- out). Previously, extra message traffic might have been generated. - Asynchronous messaging now functions correctly on Japanese Windows 95 when using the MSMQ COM objects. - Fixes a problem in the MSMQ COM objects when referencing the response and admin queue properties of a message for queues not explicitly refreshed from the MQIS. - In Windows 95, calling MQOpenQueue with a DIRECT format no longer blocks for a long time. - If the Windows NT 4.0 licensing service isn't running, then MSMQ per- seat licensing is no longer enforced. - A specific call to MQLocateBegin no longer causes an exception on the MQIS server. This could have occurred previously when the Label restriction specified with an incorrect vt argument (anything other than VT_LPWSTR). - MSMQ applications can be run by users logged on to local machine accounts. Note that this used to work anyway for shadowed local accounts -- i.e., for accounts that had "identical" local accounts (user name/password) on the server machine. The default security for queues created by such users is that everyone is granted full control (in particular, read and delete permissions). - A new MQIS update/restore utility is supplied that enables administrators to seamlessly recover crashed MQIS servers. See support\msmq.nt\MQISwizard.doc for more information. 220.127.116.11 Microsoft Transaction Server (MTS) MTS is updated with a new Java Context class. If you're building applications using Visual J++, you can use the new Context class instead of IObjectContext. The Context class allows you to do the following using Visual J++: - Declare that the object's work is complete. - Prevent a transaction from being processed, either temporarily or permanently. - Instantiate other MTS objects and include their work within the scope of the current object's transaction. - Determine whether a caller is in a particular role. - Determine whether security is enabled. - Determine whether the object is executing within a transaction. See the Visual J++ section of the Programmer's Reference for complete documentation of the new class. 18.104.22.168 SMTP, NNTP Simple Mail Transport Protocol (SMTP), Network News Transport Protocol (NNTP) enhancements are available in this Service Pack. SMTP now supports the following services: - Multiple virtual servers, or sites. - ETRN command for dequeuing mail over dial-up connections. To enable this functionality: 1. Create a text file with the following text: set obj = GetObject ( "IIS://localhost/smtpsvc" ) obj.Put "SmtpServiceVersion", 2 obj.SetInfo NOTE: This is an Active Directory Service Interface (ADSI) script that will update a value in the metabase. 2. Save this file as Enable.vbs. 3. From a command prompt, type the following and press ENTER: cscript enable.vbs For more information, go to the Knowledge Base at http://support. microsoft.com/support/ and search for KB article Q183476. You can also point to specific KB articles using the following example: http://support.microsoft.com/support/kb/articles/Q151/8/60.asp 1.1.16 Security Configuration Manager (SCM) Security Configuration Manager (SCM) is an integrated security system that gives administrators the ability to define and apply security configurations for Windows NT Workstation and Windows NT Server installations. SCM also has the capability to perform inspections of the installed systems to locate any degradation in the system's security. For further information on SCM, including installation and usage instructions, refer to Readme.txt in the \Mssce folder. 1.1.17 Web-based Enterprise Management (WBEM) WBEM/WMI is Microsoft's implementation of Web-Based Enterprise Management (WBEM), the new standard for representation of management information as supported by the Desktop Management Task Force. It surfaces important management data from Windows NT and makes it freely available to any management tool through a number of well-defined interfaces so that management of Windows NT becomes much easier (included on CD-ROM only). For more information on WMI, see http://www.microsoft.com/management/wbem. WBEM consolidates and unifies the data provided by existing management technologies. WBEM focuses on solving real enterprise issues by tracking problem areas from the user/application level through the systems and network layers to remote service/server instances. For more information, see http://wbem.freerange.com/. You can download the Web-Based Enterprise Management Software Developer's Kit (SDK) at http://msdn.microsoft.com/developer/sdk/wmisdk/default.asp. 1.1.18 Microsoft Windows NT Server NetShow Services SP4 contains an updated version of NetShow Services located on this CD in the \NetShow folder. NetShow Services enables Internet service providers (ISPs) and organizations to deliver the highest-quality audio and video at every bandwidth across the Internet or enterprise networks. This release of NetShow Services features greatly enhanced audio and video that delivers the best user experience. Simplified setup, configuration, and administration of the NetShow server components and tools give ISPs a reliable and cost-effective platform for hosting large amounts of content. Consult the NetShow Services information page (\NetShow\ntsp4-ns.htm) for details on installing and configuring this product. Before installing this product, you should also carefully review the NetShow Services release notes at \NetShow\ns-readme.htm. 1.1.19 Microsoft Windows Media Player Microsoft Windows Media Player replaces Microsoft ActiveMovie as well as the Microsoft NetShow Player. Windows Media Player has all the features found in both of the other multimedia players, plus many more. It also upgrades existing Windows Media Player and ActiveMovie support to provide convenient access to new Windows Media content. Windows Media Player supports most local and streaming multimedia file types including WAV, AVI, QuickTime, RealAudio 4.0 and RealVideo 4.0. The new player takes over the class IDs of the previous players. After you install the new player, programs that used the old class IDs will function as usual. Windows Media Player is located in the \Mplayer2 folder on the compact disc. 1.1.20 Security Privilege Must Be Enabled to View Security Event Log SP4 includes a bug fix in the Event Log service that requires that the SE_SECURITY_NAME privilege, also known as the Security privilege, be enabled in order to view and manage the security event log. By default, Windows NT grants the privilege to administrators and local System. In order to take effect however, the privilege must also be enabled in the program accessing the security event log. Prior to this change, members of the Administrators group and services running as local System could open the security log for read or change access without enabling the Security privilege. If the privilege was removed from the Administrators group, members of the Administrators group could still manage the security log. This change enforces the security model that administrators need to be granted the privilege to manage the security log; they won't be able to manage the log simply because they are members of the Administrators group. Administrators can always grant themselves the Security privilege to manage the security log, however, although this event can be audited. For more information, consult the Knowledge Base at http://support. microsoft.com/support/ and search for KB article Q188855. 1.1.21 Dynamic Host Configuration Protocol (DHCP) This Service Pack includes several quality improvement fixes to correct known Dynamic Host Configuration Protocol (DHCP) issues reported for Microsoft DHCP Server, the DHCP Manager administration tool, and for Microsoft DHCP-enabled clients running under earlier released versions of Windows NT 4.0.

SP4 will update your RRAS system to RRAS Hotfix 3.0 components automatically. If you install RRAS after installing SP4, you must reinstall SP4 to get the updated RRAS files to ensure RRAS will work properly. For more information on RRAS Hotfix 3.0, see http://support.microsoft.com/support/kb/articles/Q189/5/94.asp. 1.1.24 PPTP Performance and Security Update SP4 now includes new performance and security updates to PPTP that greatly increase data transfer speeds and enhance security. The PPTP client and server system must both be running the updated files to get the new benefits. For more information, see http://support.microsoft.com/ support/kb/articles/q189/5/95.asp 1.1.25 NTLMv2 Security SP4 contains an enhancement to NTLM security protocols called NTLMv2, which significantly improves both the authentication and session security mechanisms of NTLM. For more information, see http://support.microsoft.com/support/kb/articles/q147/7/06.asp. 1.1.26 Secure Channel Enhancements SP4 contains an enhancement to the secure channel protocols used by member workstations and servers to communicate with their domain controllers and by domain controllers to communicate with other domain controllers. In addition to authentication, you can now encrypt and check the integrity of these communications. For more information, see http://support.microsoft.com/support/kb/articles/ q183/8/59.asp 1.1.27 IP Helper API (IPHLPAPI) The IP Helper API provides Windows network configuration and statistics information to Win32 applications. The public API is available on Windows NT 4.0 and above, and Windows 95 and above. SP4 updates the API with a new .dll so that applications can communicate to a TCP/IP stack. 1.1.28 Event Log Service This Service Pack contains new features in the Event Log Service to assist how administrators measure the reliability and availability of Windows NT. The SP4 Event Log Service records three new events in the system event log that are useful in measuring operating system availability: - Clean Shutdown Event (Event ID: 6006) - Dirty Shutdown Event (Event ID: 6008) - System Version Event (Event ID: 6009) See section 3.12, "Event Log Service," for more information. 1.1.29 Domain Name Server (DNS) Service This Service Pack includes several quality improvement fixes to correct known Domain Name Server (DNS) issues reported for Microsoft DNS Server and the DNS Manager administration tool. These fixes address specific problems described in the Q184693 "DNS/DHCP/WINS Release Notes for Windows NT 4.0 SP4 Update" article in the Knowledge Base. You can obtain the specific article from Microsoft Support Online at http://support. microsoft.com/support. 1.2 Downloading and Extracting the Service Pack ------------------------------------------------ If you have downloaded this Service Pack from an FTP site or a Web site, you should read the release notes completely before you extract and install the Service Pack.

This requires at least 80 megabytes (MB) of free space on the drive on which Windows NT is installed. This is 40 MB for the uninstall folder and 40 MB for the Service Pack updated system files. To uninstall SP4, double-click the Add/Remove Programs control panel. Select Windows NT 4.0 Service Pack 4, and click Add/Remove. If this option isn't available, run Spuninst.exe from the \%systemroot%\ $NtServicePackUninstall$\spuninst\ folder. NOTE: If you install any applications or services that require SP4 or have bug fixes contained in SP4, uninstalling SP4 could adversely affect those applications. If you want to uninstall SP4, the drive letter for the boot drive must be the same as when you installed SP4. If you change the drive letter for the boot drive, you can't uninstall SP4. To uninstall Service Pack 2 and Service Pack 3, you had to run Update.exe and then select "Uninstall a previously installed Service Pack." This returned your system to its previous state. After your system restarted, the Update.exe program replaced the files updated by the Service Pack with most of the files from the previous installation and returned most of your registry settings to what they were before that Service Pack was installed. NOTE: If you uninstall SP4 on a system that previously had Service Pack 3 (without Internet Explorer 4.0) installed on it, cryptography won't work correctly after the uninstall completes. To work around this issue, reinstall Service Pack 3 after you have uninstalled SP4. Uninstalling SP4 won't uninstall new versions of CryptoAPI and SChannel. NOTE: If you plan to install a previous Service Pack after uninstalling SP4, take note of the following important precaution. SP4 modifies the Security Account Manager (SAM) database and the Security database such that older versions of the Samsrv.dll, Samlib.dll, Lsasrv.dll, Services.exe, Msv1_0.dll and Winlogon.exe files no longer recognize the database structure. Therefore, the uninstall process doesn't restore these files when uninstalling SP4. If you install a prior Service Pack (for example, Service Pack 3) after uninstalling SP4, click "No" on the "Confirm File Replace" dialog boxes that ask if you want to overwrite Samsrv.dll and Winlogon.exe. If you overwrite the newer files with these older versions, you'll be unable to log on to the system. NOTE: If you're reinstalling SP4 after installing new software or hardware, you must choose to create a new Uninstall folder. To retain your ability to back out to a bootable configuration, copy the current Uninstall folder to a safe location before running the SP4 installation program. 2.4 Year 2000 Service Pack Installation ---------------------------------------- Windows NT Service Pack 4 contains fixes for known Year 2000 issues in the Windows NT 4.0 operating system. To install the Year 2000 Service Pack from compact disc: Installing the Service Pack using Update.exe will update all necessary files on your Windows NT 4.0 installation. It will also detect and inform you if any additional Microsoft components that require updating to resolve known Year 2000 issues in the Windows NT 4.0 operating system. Follow the procedure below to update your computer to resolve known Year 2000 issues. Run the Y2ksetup.exe program located in the \I386\Update (for x86-based computers) or \Alpha\Update (for Alpha-based computers) folders on the Service Pack 4 compact disc. This program automatically updates operating system components as detected to resolve known Year 2000 issues. Note that this installation will require the system to be restarted one or more times. There is no uninstall option available for Y2ksetup.exe. To install the Year 2000 Service Pack via the Web or FTP: Install the base Service Pack from one of the locations below to your computer: http://support.microsoft.com/support/ntserver/content/servicepacks/ http://support.microsoft.com/support/downloads/ The download program will automatically detect which files need to be updated. Once prompted with the File Download dialog, select "Run this program from its current location" to perform a patched installation. This will also detect and inform you if any additional Microsoft components require updating to resolve known Year 2000 issues on your Windows NT 4.0 operating system. Follow the procedure below to resolve known Year 2000 issues. Download the Year 2000 Service Pack (y2ksp4i.exe or y2ksp4a.exe) from one of the locations below to your computer: ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/ http://support.microsoft.com/support/ntserver/content/servicepacks/ http://support.microsoft.com/support/downloads/ Run the self-extracting executable to expand the package. Run Y2ksetup.exe from \I386\Update (for x86-based computers) or \Alpha\Update (for Alpha- based computers) folder at the target location. This program automatically updates operating system components as detected to resolve known Year 2000 issues. Note that this installation will require the system to be restarted one or more times. There is no uninstall option available for Y2ksetup.exe. If you need to reinstall this Service Pack, run Update.exe from the \I386\Update or \Alpha\Update folders. It isn't necessary to uninstall the Service Pack previous to running Update.exe more than once on the same system. Use \I386\Update\Y2ksetup.exe or \Alpha\Update\Y2ksetup.exe to resolve known Year 2000 issues in the Windows NT 4.0 operating system. There are installation switches that can be used with Y2ksetup.exe. The following switches are available: Y2KSETUP [-q] [-d] -q silent mode installation -d display only (does not install, only displays those operating system components on the computer that contain known Year 2000 issues) 2.4.2 Site Server Express 3.0 There are known Year 2000 issues in the following components of Site Server Express 2.0: - Content Analyzer - Usage Analyst Installing Site Server Express 3.0 directly from the Web or from the CD doesn?t remove these components from your computer. You must install Y2ksetup.exe to remove these components from your computer and install Site Server Express 3.0, which contains an update for: - Usage Analyst - Posting Acceptor An updated version of the Content Analyzer will be available for download from the Windows NT Service Pack 4.0 Web site. Known Site Server Express 3.0 setup issues: - When Y2KSetup installs Internet Explorer 4.01 SP1 and Site Server Express 3.0, two IIS virtual roots that are required by Posting Acceptor aren't created. It's recommended that you reinstall Site Server Express 3.0 by running Ssx.exe from the \Ssx folder on the CD. 2.4.3 FrontPage Server Extension Year 2000 Issues Releases of FrontPage 1.0, FrontPage 1.1 and FrontPage 97 are not Year 2000 compliant. Releases of FrontPage 98 resolve known Year 2000 issues. If you have NTOP installed, you will have FrontPage 98 Server Extensions. It's possible to have two or more versions of the FrontPage Server Extenders on your computer at one time. The installation of a version that isn't Year 2000 ready doesn't mean that you are actively running that version. To determine which version of the FrontPage Server Extenders are actively in use on computers with FrontPage 98 or earlier - Run the FrontPage Server Administrator (Fpsrvwin.exe). - Click on each of the Web servers or virtual servers listed in the box in the upper left area, which have been configured with the FrontPage Server Extenders. - The version number of the FrontPage Server Extenders is displayed to the right of the list. Version numbers where the first digit is 3 or greater resolve known Year 2000 issues (e.g. 22.214.171.1246). If the first digit of the version number is a 1 or 2, then you should download and install the latest version of the FrontPage Server Extenders. Refer to http://www.microsoft.com/frontpage/ for details on the latest available version is and how to download. 2.4.4 IBM PS/1 ValuePoint There are known Year 2000 issues for Windows NT version 4.0 on 2.4.4 IBM PS/1 ValuePoint computers. To fix these known issues, you must upgrade Ntdetect.com in order to resolve known Year 2000 issues in older versions. From the \Ps1 folder on the CD, copy Ntdetect.com to the root of your primary boot partition on your computer. You do not need to reboot. For more information, go to the Knowledge Base at http://support. microsoft.com/support/ and search for KB article Q194301. For Year 2000 issues regarding Microsoft products or definitions regarding Year 2000 compliance, as used herein, see our Web site at http://www.microsoft.com/year2000. 3.0 USER NOTES =============== This section covers information that is specific to this Service Pack release. 3.1 Emergency Repair Disk -------------------------- If you use the Windows NT Emergency Repair Disk to repair your Windows NT system, which requires you to supply the original Windows NT media at some time after you install Service Pack 4, you'll need to reinstall SP4 after the repair is completed. This is because the Emergency Repair Disk repairs your system by restoring your original Windows NT 4.0 system files. After the repair is completed, follow the Installation Instructions (Section 2.0) to reinstall SP4. For more information on using the Windows NT Emergency Repair Disk utility, go to the Knowledge Base at http://support.microsoft.com/support/ and search for KB article Q146887. NOTE: To use the Emergency Repair Disk utility, you must have the updated version of Setupdd.sys. The updated version is contained in SP4. To update your version of Setupdd.sys, copy Setupdd.sys from the Service Pack to your Windows NT 4.0 Setup Disk 2 from the original product media. This will replace the older version of Setupdd.sys with the updated version. For more information, consult the Knowledge Base at http://support.microsoft.com/support/ and search for KB article Q158423. 3.2 Adding New Components to the System ---------------------------------------- If you change or add new software or hardware components to your system after you install SP4, you'll need to install the SP4 again. This is because the files included on the original Windows NT 4.0 media may not be the same as the files on the Service Pack CD. You can't install new components, such as a new keyboard or printer driver, directly from the Service Pack media. You must install new components from the original product media and then reinstall the Service Pack. For example, if you install the Simple Network Management Protocol (SNMP) service after installing SP4, you'll need to reinstall the Service Pack. If you fail to do so, you'll receive the error message "Entrypoint SnmpSvcGetEnterpriseOID could not be located in Snmpapi.dll." This is because some of the files in the SNMP service have been updated in the SP4 and you have a version mismatch. Reinstalling the Service Pack fixes the problem by copying the newer versions of the files to your system. NOTE: SNMP security provides the ability to set a permission level on the SNMP agent computer. The permission level determines how the SNMP agent computer will process requests from an SNMP community. 3.3 Installing Symbol Files from the CD ---------------------------------------- Each program file in Windows NT has a corresponding symbol file that is used to find the cause of kernel STOP errors. The symbols for SP4 files are compressed in self-extracting executables named Sp4symi.exe and Sp4syma.exe, for Intel and Alpha respectively. To install the symbol files corresponding to the new binaries in SP4, run the executable and when prompted, specify the path to the location of the previous version's symbols (for example, c:\winnt\symbols\). This copies the SP4 .dbg files over the existing versions of these files. For more information about debugging in Windows NT, see Chapter 39, "Windows NT Debugger," in the Microsoft Windows NT 4.0 Workstation Resource Kit. 3.4 Hardware Compatibility with Windows NT 4.0 ----------------------------------------------- 3.4.1 Video Drivers Due to incompatibilities between the ATIRage drivers and Service Pack setup, the files Ati.sys and Ati.dll haven't been included with SP4. Any ATI drivers currently installed on your system will still function normally. If you install SP4 over SP3 on a computer that has a Number Nine Visual Technologies Imagine 2 video card and drivers installed, you may experience some loss of functionality in the video driver, such as loss of any resolutions requiring 256 or more colors. If you uninstall SP4 and revert to SP3, the Imagine 2 card may be unable to display 256 colors or higher. There is no known resolution for either of these two issues because reinstalling the Imagine 2 video drivers doesn?t restore the lost functionality. Number Nine is aware of this issue and is working on a fix. 3.4.2 Dell Latitude Systems If you're running Windows NT 4.0 on a Dell Latitude portable computer, your Dell-supplied Softex Advanced Power Management and PC Card Controller services (versions 2.0 and above) will continue to function after you install SP4. Softex version 1.0 will stop functioning after SP4 installation. To update your system for SP4, install version 2.19 or later of the Softex utilities, available from http://support.dell.com/ filelib/. Your computer will become unusable if you reinstall any version of Softex prior to 2.19 after installing SP4. 3.4.3 Softex/Phoenix Utilities If you're using any of the following Softex Incorporated or Phoenix Technologies utilities, you may encounter problems running SP4: - Softex PC Card Controller, or Phoenix CardExecutive for Windows NT - Softex Power Management Controller, or Phoenix APM for Windows NT - Softex Docking Controller, or Phoenix NoteDock for Windows NT - Softex DeskPower Controller, or Phoenix DeskAPM for Windows NT Follow these guidelines: 1. Obtain the version number of the utilities you're using. 2. You must be running version 2.19 or later of the Softex or Phoenix utilities to avoid problems with SP4. Don?t install or reinstall any version of Softex or Phoenix utilities earlier than 2.19 on your system, or your system might not boot. For more information, visit the Softex Incorporated Web site at http://www.softexinc.com or Phoenix Technologies at http://www.phoenix.com. 3.4.4 255 SCSI Logical Unit Support Windows NT 4.0 detects only the first 8 logical units on a SCSI device. To work around this limitation, install SP4 and add the following key in the registry: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \[Driver Service Key]\Parameters\Device[N] LargeLuns: REG_DWORD: 0x1 where [Driver Service Key] is your SCSI driver name and [N] is the SCSI bus number. 3.4.5 IBM PS/1 ValuePoint There are known Year 2000 issues for Windows NT version 4.0 on this computer. It's necessary to upgrade Ntdetect.com in order to resolve known Year 2000 issues in older versions. From the \Ps1 folder on the CD, copy Ntdetect.com to the root of your primary boot partition on your computer. You do not need to reboot. For more information, go to the Knowledge Base at http://support. microsoft.com/support/ and search for KB article Q194301. 3.4.6 SystemSoft Card Wizard If your computer contains SystemSoft Card Wizard version 3.x and you have installed SP4, you may have lost socket services functionality. To workaround this issue reinstall SystemSoft Card Wizard version 3.x or higher after installing Service Pack 4. Or you can copy Pcmcia.sys from the Service Pack 4 Uninstall folder, $ntservicepacekuninstall$, to the \%systemroot%\System32\Drivers folder on your computer. Reboot the computer. 3.5 DIGITAL Alpha Notes ------------------------ 3.5.1 Using Remotely Possible 32 with Matrox Millennium Display Adapter If you use Remotely Possible 32 on an Alpha with a Matrox Millennium display adapter, don't use the Matrox drivers. Otherwise, your computer bluescreens after rebooting. You must use VGA-compatible display adapter drivers to use Remotely Possible 32. 3.5.2 Lotus Notes 4.5 If you want to use Lotus Notes and Internet Explorer 4.01 on an Alpha computer that runs Windows NT 4.0, you must follow this sequence when installing SP4: 1. If you have Internet Explorer 4.01 on your computer, uninstall it. 2. Install SP4. 3. Install (or reinstall) Lotus Notes. 4. Install Internet Explorer 4.01 from the SP4 CD. This problem will be fixed in a future release. 3.5.3 Alpha Fixes in SP4 These notes describe problems on Alpha systems that have been resolved since the Windows NT 4.0 Service Pack 3 release. NOTE: Windows NT 4.0 SP4 ships with HAL Revision D. This revision is also currently available from Compaq. 126.96.36.199 System Hangs on Alpha Systems with Only One Processor Physically Present The following Alpha systems, with only one processor physically present, no longer hang when booted: AlphaServer 4x00 AlphaServer 1200 AlphaStation 1200 DIGITAL Server 5000 DIGITAL Server 7000 188.8.131.52 Clock Interrupt Period Changed from 7.5 ms to 10 ms In Windows NT 4.0 SP4, the effective clock interrupt period on the following systems was changed from 7.5 ms to 10 ms: AlphaServer 4x00 AlphaServer 1200 AlphaStation 1200 DIGITAL Server 5000 DIGITAL Server 7000 This change will provide parity with Intel systems and alleviate performance anomalies caused by assumptions of 10 ms for the resolution for timers (which is equal to the clock interrupt period). 184.108.40.206 Pyxis Error Registers HAL Revision D, which ships with Windows NT 4.0 SP4, supports updated Pyxis error registers, which provide more meaningful information during hardware crashes. 220.127.116.11 Peer-to-Peer DMA Transfers This Service Pack, together with the current AlphaBIOS firmware, now allows peer-to-peer DMA transfers. 18.104.22.168 PCI Devices with 256 MB of Memory or Greater The following Alpha platforms now support PCI devices with 256 MB of memory or greater for memory-mapped I/O: AlphaServer 1000 5/xxx AlphaServer 1000A 5/xxx AlphaServer 800 or Digital Server 3000 AlphaStation 600 AlphaStation 500 Alpha XL 3xx 22.214.171.124 Alpha Machines Sometimes Hang When Rebooting The following systems no longer hang during an attempted reboot: AlphaServer 4x00 AlphaServer 1200 AlphaStation 1200 DIGITAL Server 5000 DIGITAL Server 7000 126.96.36.199 I/O Performance Degradation or a Hung Machine Under Heavy I/O Loads On Alpha machines with heavy I/O loads, certain device drivers consumed too many DMA map registers. This sometimes caused poor I/O performance or a hung machine. SP4 allows a greater number of DMA map registers. 188.8.131.52 Crashes on Alpha systems with STOP Code 0x0A Minor "correctable" hardware errors no longer generate crashes with STOP code 0x0A on following machines: AlphaServer 1000 5/xxx AlphaServer 1000A 5/xxx AlphaServer 800 or Digital Server 3000 AlphaStation 600 AlphaStation 500 AlphaStation 600A Alpha XL 3xx 3.5.4 DIGITAL Ultimate Workstation 533 SP4 won't update the Hal.dll file on the system because Hal.dll is marked as an OEM file. To work around this, you must manually copy Halrawmp.dll from SP4 to your system. To do this, first locate the Hal.dll file on the system (in the OSLOADER subfolder), and then copy Halrawmp.dll from SP4 to this folder, renaming it Hal.dll. 3.5.5 Installation Fails on Alpha Machines with Windows NT Option Pack 1.0 Installed Security Configuration Manager (SCM) doesn't install on Alpha machines that have the Windows NT Option Pack 1.0 for Alpha installed. This is because the Mfc42u.dll file installed by the Windows NT Option Pack isn't compatible with SCM. To work around this, replace Mfc42u.dll installed by Windows NT Option Pack 1.0 for Alpha with Mfc42u.dll from the Windows NT4.0 CD or from Visual C 6.0. This may cause problems with the applications in the Windows NT Option Pack 1.0 for Alpha. This will be fixed in the next release of Windows NT. 3.5.4 Microsoft Transaction Server and Distributed Transaction Coordinator The file TestOracleXAConfig.exe isn't automatically installed on DEC Alpha- based computers. If you are installing Windows NT 4.0 SP4 on an Alpha-based computer and will be using Microsoft Transaction Server (MTS) or the Distributed Transaction Coordinator (DTC) with an Oracle or XA- compliant database, you must manually copy this file from the CD-ROM to the %sysroot%\system32 folder on your hard drive. The symbol %sysroot% represents the installation folder for Windows NT. For example, if your installation folder is C:\Winnt, you would copy it to C:\Winnt\Wystem32. TestOracleXAConfig.exe is located in the \Alpha folder on the Windows NT 4.0 SP4 CD-ROM. If you are installing Windows NT 4.0 SP4 on an Intel-based computer, TestOracleXAConfig.exe is automatically installed during Setup. 3.6 Running Windows NT Administrative Tools from Remote Server --------------------------------------------------------------- In order to run administrative tools from a remote server, you must upgrade the remote server to Service Pack 4. If you attempt to run administrative tools from a remote machine that hasn't also been upgraded to Service Pack 4, they will fail to load or won't function properly. 3.7 CryptoAPI and Authenticode ------------------------------- The Authenticode environment won't be set up correctly for existing user accounts on upgrades from Windows NT 4.0 systems running Internet Explorer 3.02. This doesn't affect new user accounts created on the system. Also, upgrades from Windows NT 4.0 systems with Internet Explorer 4.0 or later aren't affected. Each user needs to enter the following command line in a command prompt window before they use Authenticode: setreg 1 false 2 true 3 false 4 false 5 true 6 false 7 true 8 false 9 false 10 false Setreg.exe isn't part of SP4; you can download it as part of the CryptoAPI tools. You can install the latest CryptoAPI tools (Internet Explorer 4.0 or later) from the Platform SDK on MSDN. The CryptoAPI tools (also known as Authenticode Signing tools) that were released for Internet Explorer 3.02 are no longer supported. Tools released for Internet Explorer 4.0 will continue to work on Service Pack 4. If you install SP4 on a system with Internet Explorer 4.0 or later and then uninstall Internet Explorer, newer CryptoAPI components will be partially uninstalled. This problem doesn't affect the system if Internet Explorer 4.0 was installed after SP4. Reinstall SP4 after uninstalling Internet Explorer for full functionality. To ensure proper CryptoAPI functionality, it?s recommended that you install Internet Explorer 3.02 or later before you install SP4. The following is a list of known problems when Internet Explorer 3.02 or later is installed after SP4: - Certain CryptoAP2 networking functions have a dependency on Wininet.dll and may fail if Wininet.dll isn't on the system. To work around this, install Internet Explorer 3.02 or later before installing SP4. - Certificate revocation checking fails if you install Internet Explorer 4.0 after you install SP4. To fix this, reinstall SP4 after installing Internet Explorer 4.0. This will be fixed in a future release of Internet Explorer. - Certain CryptoAPI-related file extensions (.Cer, .Crt, and .Der) aren't registered correctly when Internet Explorer 4.0 is installed after SP4. To restore the file extension registration, run the following command line: Regsvr32.exe cryptext.dll This will be fixed in a future release of Internet Explorer. 3.8 Uninstalling Internet Explorer ----------------------------------- On a system that had Internet Explorer 4.0 or later installed and then had SP4 applied, uninstalling Internet Explorer will partially uninstall newer CryptoAPI components. Reinstall SP4 after uninstalling Internet Explorer. This problem doesn't affect the system if Internet Explorer was installed after SP4. 3.9 Certificate Server Notes ----------------------------- 3.9.1 Known Problems and Limitations: 1. Be sure to consult the release notes for the Certificate Server version 1.0 as shipped with the Windows NT Option Pack. Also consult the QFE update release at ftp://ftp.microsoft.com/bussys/ iis/iis-public/fixes/usa/certserv. 2. Do not perform an initial installation of Certificate Server on February 29th of a leap year. The validity period for the server will be set incorrectly. To work around this, set the machine time to the day before (February 28th), perform the installation, and then reset the machine time back to February 29th. There is no problem issuing certificates on February 29th, once the certificate server is successfully installed (as noted above). 3. If you install Certificate Server on top of SP4, you may receive a "Some system services could not start" error message upon system startup. Click OK to continue, and check the Event Viewer log for the specific error. Event ID: 7000 Source: Service Control Manager Description: The Certificate Authority service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. Event ID: 7009 Source: Service Control Manager Description: Timeout (120000 milliseconds) waiting for service to connect. There are no workarounds for this problem. 3.9.2 Virtual Directory Attributes for Certificate Server IIS enforces the application attribute of virtual directories in such a way that the Certificate Server's administration Web pages fail. This failure appears in the form of database access errors that are identified by an E78 access failure code. You will be unable to access the Certificate Server log and queue from the administration Web pages. To work around this problem, make sure that the application attribute for the Certificate Administration (CertAdm) folder is applied. To apply the application attribute for CertAdm folder: 1. Click Start, point to Programs, point to Windows NT 4.0 Option Pack, point to Microsoft Internet Information Server, and then click Internet Service Manager. 2. In MMC, open the left pane entries until the Default Web Site is visible. 3. Double-click the Default Web Site. The right pane now contains the first level of virtual directories for the Web server. 4. Right-click the CertAdm virtual directory. 5. Click Properties. 6. In the Application Settings section of the Virtual Directory tab, click Create. 7. Click Apply, and then click OK. 3.9.3 Invalid Hash Algorithm Accepted on Installation During Certificate Server installation, don't select HMAC as the hash algorithm the Certificate Server should use when issuing certificates. Although HMAC is among the selections on the optional Advanced Settings page, this isn't a valid use of this algorithm. If HMAC is selected, installation of the Certificate Server will fail. For more information about Certificate Server, consult the Microsoft Knowledge Base. 3.10 Internet Information Server 4.0, Secure Sockets Layer and Root Certifying Authority Certificates, and the IISCA.EXE Tool -------------------------------------------------------------------- If you use Internet Information Server 4.0 (IIS) with secure sockets layer (SSL) and you have installed a root certifying authority certificate (other than those issued by well-known third parties, such as Verisign, Thawte Consulting, or Microsoft), you may need to reinstall the affected root certifying authority certificates after you install SP4. You need to do this if you're using Microsoft Certificate Server 1.0, which shipped with the Windows NT Option Pack.
