There is a policy under "User Configuration/Administrative Templates/Windows Components/Windows Explorer" called "Prevent Access to Drives from My Computer" that, when enabled, will disallow access to several different combinations of the A, B, C and D drives or even all drives.

Anyone know how to make the root of c non accessible. I have told the group policy not to allow saving of files to c however if you creat a new folder you can save to that folder. Anyone know how to stop this?
