You can map a drive, but that more than what I'm saying. you can just go to start-run and type in the path to the shared folder on another client system.

If you have a shared folder on George-PC named "photos", then the path would be \\George-PC\photos

Did you even try pinging the other systems? Since you can "see" the other workstations listed in your network, I'm guessing that you can.
