So let me get this straight. My login name is BOBBY. I can walk up to A, B, and C and load in on all 3?

AND you have configured all FIREWALLS including the one in the router to allow this? I've lost count of the number of times this is an issue. Example at http://forums.cnet.com/7726-7589_102-5412417.html?tag=posts;msg5412417 where LAN would be fine but not on WiFi.
