I am trying to use a Mac Mini Server on a network with G4's, G5's and Intel Imac's plus networked HP printers which use Appletalk on the Imacs running Leopard. I installed a Guardian Maximus 2tb Raid hard drive on the Mac Mini server. For some strange reason In can share the screen on the Mac Mini Server on all computers but cannot connect as a server from the G5's. The only difference in network setup on all machines is Apple talk is active on all Leopard machines. The G4's connect fine but not the G5's. Any ideas on what the problem might be?
