The Microsoft® Exchange Server Analyzer Tool queries the CIM_Datafile Microsoft Windows Management Instrumentation (WMI) class to verify that the Vssvc.exe file exists.
In the registry, the Exchange Server Analyzer queries to determine whether Volume Shadow Copy Service (VSS) or Virtual Disk service (VDS) is running on the Windows Server:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS
Additionally, the Exchange Server Analyzer reads the following registry value to determine which version of the Microsoft Windows® operating system is running on the Exchange server:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\CurrentVersion
If the CurrentVersion value equals 5.0, the Exchange server is running on Microsoft Windows 2000 Server. If the CurrentVersion value is 5.2, the Exchange server is running on Microsoft Windows Server™ 2003.
Finally, the Exchange Server Analyzer queries the Win32_OperatingSystem Windows Management Instrumentation (WMI) class to determine the value for the ServicePackMajorVersion key. The value for the ServicePackMajorVersion key indicates which Windows service pack is installed on the computer.
The Exchange Server Analyzer displays an error if the following conditions are true:
- Exchange Server is installed on Windows Server 2003 Service
Pack 1 (SP1).
- Volume Shadow Copy Service or Virtual Disk service is running
on Windows Server 2003 SP 1.
- The VSS update is not installed on this Exchange Server
configuration.
If you apply the VSS update, issues such as kernel resource depletion will be resolved.
To fix the error-
Apply the VSS update that is downloadable from Microsoft Knowledge Base article 891957, "Update is available that fixes various Volume Shadow Copy Service issues in Windows Server 2003" (http://go.microsoft.com/fwlink/?linkid=3052&kbid=891957).
