MMC cannot open the file C:WINDOWSsystem32gpmc.msc : FIX

GPMC Error

MMC cannot open the file C:\WINDOWS\system32\gpmc.msc

If you are receiving the following error:

GPMC Error

Simply browse to the following directory, replacing *User_Name* with the affected users sAMAccountName:

C:\Documents and Settings\*User_Name*\Application Data\Microsoft\MMC

Then delete the ‘gpmc’ file. This will reset the gpmc console to its original configuration, but allow you to use it!
