Windows could not evaluate the Windows Ma nagement Instrumentation (WMI) filter

Hello, I have a terminal server that is not mapping network drives for newer employees, even though its policy is configured to do so. This is a recent occurrence and is affecting user accounts. I attempted to delete the profile to see if it was server-wide or profile-specific and now those accounts continue logging in with temp profiles.

Below is the error when trying to force a GP Update. I've compared the settings and services with other terminal servers and they seem to be consistent.

Also, when attempting to run  GPRESULT /H GPReport.html from the cmd line, I continue receiving an access denied message regardless of the user account (even admin) and cmd elevation level (run as administrator).

C:\Users\TEMP>gpupdate /force
Updating Policy...

User policy could not be updated successfully. The following errors were encount

The processing of Group Policy failed. Windows could not evaluate the Windows Ma
nagement Instrumentation (WMI) filter for the Group Policy object cn={XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX},cn=policies,cn=system,DC=Domain,DC=LAN. This could be c
aused by RSOP being disabled  or Windows Management Instrumentation (WMI) servic
e being disabled, stopped, or other WMI errors. Make sure the WMI service is sta
rted and the startup type is set to automatic. New Group Policy objects or setti
ngs will not process until this event has been resolved.

To diagnose the failure, review the event log or run GPRESULT /H GPReport.html f
rom the command line to access information about Group Policy results.

Any help is greatly appreciated!

Thank you,

You have checked that the Windows Management Instrumentation service is running? If it is try rebuilding the WMI index. Microsoft have instructions here:
