Has anyone experienced an MMC error when trying to open up gpmc. For some "unknown" reason, when I attempt to open up gpmc, I get the following error: Microsoft Management Console MMC cannot open the file c:\windows\system32\gpmc.msc This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC. This may also be because you do not have sufficient access rights to access the file I checked, and the file is there, and the local administrators group, of which my ou admin account is a part of is listed as having Full Control? ADUC works just fine?
