PVS Gold image WMI issues fix

As part of a PVS image issue discovery project, I was able to determine that WMI was not working on several gold images which was causing several memory leaks, as well as event viewer complaining just about every 30 seconds.

Problems escalated whenXenApp hosts would completely run our of virtual memory which would end up affecting the overall user experience.

Environment:

  • Windows 2003 SP3
  • Citrix XenApp 5.0
  • PVS 6.1.16

Issue:

WMI not working on several Golden images.  My guess is this image was copied in a broken state and was replicated to many different images.

Fix:

Run the following in command line

  • Regsvr32 %SystemRoot%\System32\wbem\wmidcprv.dll
  • cd /d %windir%\system32\wbem
  • for %i in (*.dll) do RegSvr32 -s %i
  • for %i in (*.exe) do %i /RegServer

The Windows Management Instrumentation Tester window may appear, this is normal and we can go ahead to close it.

If it does not work, I also suggest you run the following commands to repair WMI namespace:

  • net stop winmgmt
  • wmic /NAMESPACE:\\root path “__namespace.name=’wmi'” delete
  • mofcomp %windir%\system32\wbem\wmi.mof
  • net start winmgmt

Restart the computer to check the result. If the issue persists, try the following steps:

  • winmgmt /verifyrepository
  • winmgmt /salvagerepository
