Everyone on the net is saying how to fix The Group Policy Client service failed the logon. Access denied by rejoining the PC to the domain and recreating the user’s profile, but no one is saying why it’s happening. To help troubleshoot this, can you:

  • Check if another user can log onto the computer without getting the Group Policy Client service failed the logon error
  • Check the event log
  • Also, if you elevate the user to an administrator of the PC (temporarily), do they still get Access denied?
  • Are there other computers on the network having the issue?
  • Is the user able to log onto another computer without group policy issues?

Did you rejoin the PC to the domain as others on the internet are suggesting?

I suspect that your group policy cache folder permissions may be corrupt.

You might want to try using the cacls tool (or whatever the new version of that is called) to reset the permissions on the following folder:

C:\Windows\System32\GroupPolicy

Be warned that this might stuff the machine up, to fix it you might have to remove the PC from the domain and re-add it.
