1. Can you ping this memeber server from a PDC or BDC on your network?
2. Is a BDC or PDC available on your local area network.
The message your getting is related to either name resolution or connectivity to your PDC & BDC.
If its name resolution, did you configure your memeber server to use the wins servers on your network? If you dont have a WINS server on your network, did you add an entry in your LMHOSTS file to indicate the address of your PDC?
If its a networking problem, does your NIC card have a link light? Do you get messages about a duplicate IP address, do you get duplicate name errors? Can you ping your new memeber server from another workstation, server, PDC BDC?
