Have a SBS 2K3 in which I tried to create a new GPO and found that only 3 of the 6 policy templates were present? Only the Search, wmplayer, and wuau templates appeared, and of course could not see or make any changes to any group policy settings anywhere else. All the templates do exists in my \inf folder, and I added them back into the editor. I can know see all the settings, but they all show "Not Configured" when they are. In the GPMC I can see the settings, but not in the Editor. So I tried re-installing the GPMC with no luck. Looking for ideas, I have checked the permissions, and have found no errors in the system or application event log to lead me anywhere.
Can you provide a jpg of your Group Policy Management with the Group Policy Objects expanded?
