Can anyone confirm or deny my suspicions here? I suspect that in OS X AppleTalk is being trasported "Over" TCP/IP" Here is my reasoning: I recently re-networked my office this time using a router. The 2 Macs running OS X could not find each other using AppleTalk until I corrected the TCP/IP Settings. For a brief period of time, I had one on a different "area code" of TCP/IP. I used the finder's "Go" menu and the "Connect to Server" selection. Then Clicked on Appletalk. They didn't see each other. Just curious.
