How are things? An environment was upgraded from 2003 to 2012 and for first time since the upgrade, we have had to amend the default domain policy.
When we try and do this, we get "failed to open the group policy object. you might not have the appropriate rights". "The volume for a file has been externally altered so that the opened file is no longer valid".
One point of note is that someone discovered that the default domain policy can be opened from a windows 7 machine.
