Basic Mac OSX/OSX and 9.1 networking


K - might sound like a stupid question...but I'll ask anyway...

I've got 3 Macs - (2) OSX systems and (1) 9.1 system, I can't get them to talk very well at all. I've got all my settings set to DHCP and to basically auto detect everything but they won't talk. When I go to the 'Connect to Server...' on OSX's 'Go' menu in the finder on my powerbook, itself shows up like 20 times in the list and none of the other computers. And the other two computers won't see anything at all. Also, it won't let me set any of the Appletalk zone settings. any suggestions?
