Error message when you run the SQL Server 2000 Management Pack for MOM 2005 in low-privilege scenarios: "Unable to expand message 17055 " (920707)

SYMPTOMS

After you install the Microsoft SQL 2000 Management Pack for Microsoft Operations Manager (MOM) 2005, you may receive the following error messages in the MOM 2005 alert messages for SQL Server:

Unable to expand message 17055 [-1073724769] 8957 DBCC CHECKALLOC (OnePoint) executed by NT AUTHORITY\SYSTEM found 0 errors and repaired 0 errors.

SQL Server is unable to collect events due to insufficent permissions: Unable to expand message 17177 [1073759001] 1796 6/25/2004 5:05:55 AM 6/25/2004 10:05:55 AM

This problem occurs when the MOM 2005 action account is configured to run in low-privilege scenarios.

CAUSE

This problem occurs because the service account under which the MOM service is running does not have access to the following resource files:

SQLEVN70.rll
SQLAGENT.dll

Additionally, the Network Service account is not added to the discretionary access control list (DACL) for these files during setup. Therefore, if the MOM service account runs under the Network Service account, the service will not have access to these files.

RESOLUTION

To resolve this problem, add the service account under which the MOM service is running to the DACL for the following files:

\Program Files\Microsoft SQL Server\MSSQL\Binn\Resources\1033\SQLEVN70.rll
\Program Files\Microsoft SQL Server\MSSQL\Binn\SQLAGENT.dll

Note You should grant the read and execute permissions to the service account under which the MOM service is running to the DACL.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

By default, the MOM service runs under the Network Service account when MOM 2005 is installed on a Windows Server 2003-based server. The MOM service may run under the Local System or the Network Service account when MOM 2005 is installed on a Windows 2000 Server-based server.
