I have a Vista Ultimate and a 7 Ultimate computer on the home network. The 7 computer can access some of the Ultimate shares, but cannot access one of the hard drives. It's shared with the same permissions (I even have "Everyone" allowed to do anything), but I'm still getting a "You do not have permission" error. I even added my username/password that I use to log into the 7 computer onto the Vista computer as a user. Any further advice would be appreciated.
