I just got my system back from the shop(new mboard, new ram, new vcard, new processor)...pretty much new everything minus network card. We are on Windows Nt 4 and I was going to power things up and connect to the network. However, the computer will not join our domain and I keep getting this error, "DHCP failed to obtain a lease for the card...semaphore timeout period has expired" I have tried to release and renew but still the same problem. I was wondering if anyone knows a way around this...Thanks!
