I have two Macs running 10.4.8 on a wireless network. Clicking the Network icon on my G4 Powerbook shows the G5 iMac, but on the iMac, the Powerbook does not appear. I can connect from iMac to Powerbook using the 'Connect to Server' command and inputting the IP address, but as the IP is dynamic, that's a pain. Sharing options are identical on both. Any ideas why the iMac is not showing other Macs on the network? Thanks in advance....
