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:

DeferredInit
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
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.
