As per MSW2KDB
, this error indicates that Windows Management Instrumentation (WMI) is not functioning correctly. As a result, the client-side extension can not process Resultant Set of Policy (RSoP) information. Even though Group Policy might have been successfully applied, the RSoP diagnostic information is not available.
Per Microsoft: “This behavior may occur if you have a Microsoft Windows 2000 domain that includes Windows Server 2003-based servers, and you apply Internet Protocol security (IPSec) policies by using Group Policy. These event messages appear in the Application event log every time that these policies are applied on the Windows Server 2003-based servers”. See ME823608
to fix this problem".
From a newsgroup post: "Please perform the following actions and check how things go after each step:
1. At the cmd line enter (run the following commands from the windows\system32\wbem folder and hit enter after each line):
- mofcomp exwmi.mof.
- mofcomp -n:root\cimv2\applications\exchange wbemcons.mof.
- mofcomp -n:root\cimv2\applications\exchange smtpcons.mof.
- mofcomp exmgmt.mof.
- mofcomp rsop.mof.
- mofcomp rsop.mfl.
- cd back down one level to windows\system32 and run the following:
- regsvr32 /n /i userenv.dll.
- reboot the system.
- After the reboot, you should no longer see the event. However if you still see event 1091 after reboot, re-register the security client dll by running the following commands:
- regsvr32 /u scecli.dll.
- regsvr32 scecli.dll.
2. Perform a gpupdate and see if event 1090 from source Userenv is gone.
3. If the event is still present, read ME281888
for further troubleshooting information.
4. Run the following switches:
winmgmt /regserver winmgmt /resyncperf winmgmt –e.
5. Reboot and perform a gpupdate. See if the event is gone".
