Osx Connecting to Servers Running 9.2.1


I have just installed OSX 10.4.2 on my titanium and an now unable to connect to any of my other macs (PowerMac G3 beige desktop, G3 laptop both running 9.2.1). I get the message "the file server uses an incompatible version of AFP protcol. You cannot connect to it" when I try to connect with an alias of the server made when OSX 10.2.8 was installed. Now I cannot even see any of the other servers when attempting to browse from the "Connect to Server" window. When I boot the Titanium in 9.2.2 I have access to all the other servers.

What do I need to do to be able to have access to these other server while in OSX 10.4?
