I log on to my PC with a regular account and use Runas to administer AD. I have ShellRunas and the RSAT installed. ADUC and GPMC all work fine running as a different user.When I make a custom mmc and try to run it as a different user I get the error "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access them."I tried turning off UAC but that didn't work. Any ideas what to do here?

Hi,Please create a new admin profile and logon to the new profile for a test. Is MMC Console opened successfully? If not, please restart the machine in Safe Mode to check the result.Thanks,Novak

If I create a folder and give my Domain Admin account Full control, I can then "Run as a Different user". That account is in the local admins groups, so it's strange I have to give it explicit permissions to be able to run a custom mmc.
