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.

    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:

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.
