Knowledge Base article:

Summary

UserEnv experienced an error applying Group Policy to the domain controller. Group Policy must be applied successfully for domain controllers to function properly because domain controllers get several critical permissions, such as Access this computer from network, through policy.

Because of the architecture of UserEnv, Microsoft Operations Manager (MOM) is unable to directly report the specific problem.

Sample Event:

Windows cannot read extensions from registry. Group Policy processing aborted.

Resolutions

To enable UserEnv logging, see Knowledge Base article 221833, “How to Enable User Environment Debug Logging in Retail Builds of Windows,” at http://go.microsoft.com/fwlink/?LinkId=25636. The log file provides details for the specific error.
