I ran into this error this morning after the servers came up from a reboot because of updates, one of the DC’s could not get/apply the group policy.
Here is a sample event:
Event Type: Error
Event Source: Userenv
Event Category: None
Event ID: 1058
Date: 6/12/2009
Time: 9:24:43 AM
User: NT AUTHORITYSYSTEM
Computer: SERVER
Description:
Windows cannot access the file gpt.ini for GPO CN={31B2F340-016D-11D2-945F-00C04FB984F9},CN=Policies,CN=System,DC=DOMAIN,DC=local. The file must be present at the location . (Access is denied. ). Group Policy processing aborted.
All permissions were ok on the expected files.
running this fixed the issue:
dfsutil /PurgeMupCache
gpupdate /force
Mind you that the specified error could be for a number of networking/permission related issues, however if you have ruled out any connectivity issues this may solve your problem. (also note that this was not in any KB articles from MS.)
