Hi everyone, For some bizarre reason I cannot get a 2003 server machine to talk to any computers on an Ethernet network except machines running 2000 server. If I network with firewire, I do not have this problem. So to sum up: - The 2000 server machines will talk to ALL computers - The 2003 server machine will talk ONLY to 2000 server but NOT to XP or another 2003 server - The XP machines will talk to XP and 2000 server but NOT to 2003 server All the computers on the network are visible from all the computers. Can anyone help us with this? Any help would be most gratefully appreciated. TIA.
