MORE INFORMATION
You may continue to receive the following error messages:

Error message 1

Mon Nov 15 15:44:56 2004

Error 7031 from Service Control Manager

The Message Queuing service terminated unexpectedly. It has done this 5 time(s).

The following corrective action will be taken in 0 milliseconds: No action.

Error message 2

Mon Nov 15 15:44:55 2004

Error 2077 from MSMQ

Unable to save Checkpoint for the checkpoint. Message Queuing cannot operate reliably without the checkpoint.

This problem occurs because, when the MsDtcLog.dll file was updated in Windows 2000 SP4, the changes were not copied to the MqLogMgr.dll file. The MqLogMgr.dll file is a copy of the MsDtcLog.dll file. The changes in the MsDtcLog.dll file will resolve these remaining errors. To update the MqLogMgr.dll file, you can copy the MsDtcLog.mgr file to the MqLogMgr.dll file. To do this, follow these steps:  Start the computer in Safe Mode. At a command prompt, type the following two commands. Press ENTER after each command.

Rename %windir%\system32\mqlogmgr.dll to %windir%\system32\mqlogmgr.bak

Copy %windir%\system32\msdtclog.dll to %windir%\system32\mqlogmgr.dll

Note This command is not a typographical error.

 Restart the computer.
