Connection Problems


I am trying to get my 3 macs (mini w/tiger 10.4.2, powerbook w/panther 10.3.9, iMac w/panther 10.3.9) to talk to each other over airport express (updated to 4.2) (WPA 2).

I can get the mini to connect to the iMac, and I can get the Powerbook to connect to the iMac but I can not get the powerbook to connect to the mini. I have attempted to use the ip address and the .local address with no luck. There has to be something obvious that Im overlooking.

I eventually want to use the mini (with retrospect) to back up all three machines to an external firewire drive for backup purposes.
