My network consists of an old Powerbook G4 Titanium running Mac OS X 10.4.6 and a recent iMac running Mac OS X 10.6.1 . The network is run through Ethernet, not wireless.
I have issues accessing the iMac from the Powerbook. It appeared once via Finder>Network then disappeared and then reappears occasionnally, but nothing reliable enough for even a large file transfer.
Any idea what could cause this issue?
