This makes no sense. I have always had 2 cpu's on a network. My main rig, and a "server". (Basically a storage and backup cpu). Well I just built a new rig, and installed Win 7 RC. Re formatted my old "main" rig to become my new "server". I still had the old "server" (Win XP) connected to the network, and had no problems mapping the drive to my Win 7 machine, and the new server with Win XP.
Now, I took the 320GB Storage drive out of the thrid CPU and installed it in the new "server" and tried to map the drive to my Win 7 Machine. I can not for the life of me get it to work. Both machines have the same user and p/w for login. WHAT GIVES???
