Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

When trying to run the Group Policy Results Wizard against a specific workstation, I'm getting the following error:

The wizard was unable to generate the computer or user's data due to insufficient permissions.

    Details:
    Invalid class

I'm guessing that the class being referred to is a WMI class, but I haven't gotten much farther. I've run sfc /scannow on the machine with no luck. I've also followed all of the recommendations in this article: http://windowsxp.mvps.org/repairwmi.htm.

I cannot find anything useful in the event logs and I can't think of anywhere else I could look to find out what's really happening here. Any help would be appreciated.

can you run "wmic os" elevated on the problem device, do you get invalid class or a permissions problem? –  tony roth Jun 5 '12 at 15:28

I ended up using a script at http://community.spiceworks.com/scripts/show/113-rebuild-wmi to rebuild the WMI repository. RSOP is working now.
