I just upgraded a Win Server NT4 to Server 2003. Everything went well but we have big trouble with DNS and DHCP.
DHCP and DNS just won't work. All the workstations say they can't find a DHCP server or the domain.
If I hard code all the IP info on a workstation it boots OK and can find the internet using the server for DNS, but it can not find the server by name and can not find the domain to log in.
I can map drives by IP address but not by server name. I can't join the domain; it says it can't find it.
I can ping the server but not find it by name.
I removed and reinstalled DHCP and DNS to no avail. I set up WINS, but no help.
I can move DHCP to the router but that won't help the dns issue finding the server by name.
