I have a user that can't access files on either his thumb drive or CD ROM You are able to see all the files within the drive, but once he double clicks to open a PDF or Excel file, it is showing an error of "access denied". This is also happening with his CD/DVD drive as well. He put's the flash drive on another computer and has no problem opening any of the files. The computer is a Dell Latitude E6510 running Windows 7 Pro. Any help in this would be greatly appreciated!
