SYMPTOMS
========
The Microsoft Operations Manager (MOM) 2005 service does not start on a MOM Management Server even though you have made no changes to the Management Server.
Additionally, an error message that is similar to the following is logged in the MOMService.mc8 log file on the Management Server:

Err:Failed to open queue D:\Documents and Settings\All Users\Application Data\Microsoft\Microsoft Operations Manager\Config Group Name\ServerQueue.pqf: OpenFailed

Note The MOMService.mc8 log file is located in the %windir%\Temp\Microsoft Operations Manager folder.

CAUSE
======
This problem occurs because the files in the %systemdrive%\Documents and Settings\All Users\Application Data\Microsoft\Microsoft Operations Manager\Configuration Group Name folder are corrupted.

RESOLUTION
=============
To resolve this problem, clear all the files in the %systemdrive%\Documents and Settings\All Users\Application Data\Microsoft\Microsoft Operations Manager\Configuration Group Name folder by using the MOM Information Utility (MOMInfo.exe). This utility is included in the MOM 2005 Resource Kit. For example, type mominfo.exe /clearqueue to clear all files.
Note If the MOM service still does not start after you use this utility, move the files in the %systemdrive%\Documents and Settings\All Users\Application Data\Microsoft\Microsoft Operations Manager\Configuration Group Name folder to a temporary folder, and then start the MOM service.
