Today I noticed several clients which have not updated any GPOs for a while. Even a “gpupdate” was not successful:
After a some troubleshooting, the local group policies could be determined as the cause (as already noted in the error above). As viewing or editing via “gpedit.msc” was also no longer possible.
The only solution was to reset the local GPOs. This can be done via CMD or Powershell.
ATTENTION:
All locally defined group policies are lost and have to be reset!
CMD
RD /S /Q "C:\Windows\System32\GroupPolicyUsers" && RD /S /Q "C:\Windows\System32\GroupPolicy"
Powershell
Remove-Item 'C:\Windows\System32\GroupPolicyUsers' -Recurse -Force
Remove-Item 'C:\Windows\System32\GroupPolicy' -Recurse -Force
After the reset a “gpupdate” can be performed again without any problems and the GPOs will be applied again.
