IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it
if a problem occurs. For information about how to do this, view the
"Restoring the Registry" Help topic in Regedit.exe or the "Restoring a
Registry Key" Help topic in Regedt32.exe.

SUMMARY
=======

This article describes two new registry values that are available after you
install Windows NT 4.0 Service Pack 4. You can use these entries to configure
and use the Microsoft Message Queue Server (MSMQ).

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

WARNING: Using Registry Editor incorrectly can cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that
problems resulting from the incorrect use of Registry Editor can be solved. Use
Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it. If
you are running Windows NT, you should also update your Emergency Repair Disk
(ERD).

The new values are located in the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\MSMQ\Parameters

DeferredInit
------------

Value type: DWORD
Valid data values: 0 or 1
Default data value: 0

You can use this value to prevent the MSMQ service from contacting the Message
Queue Information Store (MQIS) database at startup (to prevent the Remote Access
Autodial Manager service from dialing, for example). To activate this feature,
this value must contain a data value of 1. You should use this value only if the
initial MQIS access causes unwanted dial-up activity, because this setting can
delay programs calling the MQOpenQueue service in offline situations.

WaitTime
--------

Value type: REG_DWORD
Value data values: 0x0 to 0xFFFFFFFF seconds
Default data value: 0x3C seconds (60 seconds, decimal)

This value determines the frequency with which the sending Queue Manager service
can access the Directory Service service or perform name resolution as part of
delivering outgoing messages. Use this value in environments in which TCP/IP or
IPX machine addresses are changed often. Modifying this value may also be useful
with messages submitted offline using a name format requiring access to the
Directory Service service (Public or Private formats) or to perform name
resolution (Direct format with a Universal Naming Convention or a Domain Name
System computer name).

Reducing this value minimizes the time it takes MSMQ to send messages once an
MSMQ server reconnects to the network. However, setting a smaller data value may
cause a sending Queue Manager service to spend unnecessary time attempting to
access the Directory Service service or performing name resolution. Note that
this value does not appear in the registry unless you manually add it or use a
program to change the default value.
