  Q256986 Description of the Microsoft Windows Registry

SUMMARY
=======

By default, Internet Information Server (IIS) validates an unqualified user
logon ID against either the local computer's user database or the domain which
the server is a member of. This article describes how to configure IIS to
validate the unqualified user logon against all trusting domains and the user
accounts database.

MORE INFORMATION
================

To configure IIS to validate the unqualified user logon against all trusting
domains and the user accounts database, use the appropriate method:

IIS 4.0 and IIS 5.0
-------------------

Method 1

1. Start the IIS Microsoft Management Console (MMC).

2. Right-click the desired Web site, and then click Properties.

3. On the Directory Security tab, in the "Anonymous Access and Authentication
  Control" section, cclick Edit.

4. Click Edit for Default domain for basic authentication.

5. In the Domain Name text box, type a single backslash "\" (without the
  quotation marks).

6. Click OK three times to return to the Internet Service Manager MMC.

Method 2:

You can also set the DefaultLogonDomain parameter for IIS 4.0. This parameter has
been moved to the metabase for IIS version 4.0. To do this, run Adsutil.vbs from
a command prompt, using the appropriate syntax below (depending on whether you
want to set DefaultLogonDomain for all FTP sites, only the default FTP site, or
other sites):

- To set DefaultLogonDomain for all FTP sites, run the following command:

  adsutil set msftpsvc/DefaultLogonDomain "DomainName

- To set DefaultLogonDomain for only the default FTP site, run the following
  command:

  adsutil set msftpsvc/1/DefaultLogonDomain "DomainName

- To set DefaultLogonDomain for any other site, use the same syntax as the
  default FTP site above, but change the "1" parameter to the appropriate
  service number.

Knowledge Base:

     GOPHERSVCgopher Service
     W3SVC        WWW Service

3. On the Edit menu, click Add Value, and then use the following entry:
