I am seeing the following error from time to time. It is fairly random both on occurrence and location.

There was an error while accessing content for policy "GR_Workstation_WinXP_Group_Policy(3)". The error was - "Path for the group policy content is null."

What confuses me the most is that there really is no path to set in the policy. Does this "path" mean the path on the server? What else could be the cause of this issue?
