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.

I'll just throw out some questions at random, and let someone else pickup where I leave off:
What is the current setup, what roles are your servers playing (A DNS Server, a seperate DC, sperate DHCP)?

What you have written above indicates that DHCP is not working, and therefore not assigning IP addresses, or Scope Options, such as which DNS servers the clients should use.  

So, a few quick questions there:  Is the scope on the DHCP server set up, and then has the DHCP server been authorized to serve addresses, and has the scope been activated?

Sorry if this is all terribly routine, just trying to get the big picture.

I've managed to get the workstations working by using dhcp on the router but I'd rather they use the server.  Besides dhcp not working when I browse the domain I don't see the server listed even though I can ping by name and map drives by name.

DHCP is set up, the scope is active.  Not sure what you mean by "authorized".

P.S. THere is one subnet for all.  The router is on that subnet as well.  On the server when I browse the domain the clients do not show.  I can access the server from a workstation by \\servername in Run and by searching.

Ok, glad you're up and running for now.  I run DHCP on a W2K server and I had to authorize the server before DHCP would work.  I Don't know if that has changed in 2003, but I don't think it did.  According to Microsoft, if the 2003 DHCP server is also a DC it should have automatically been authorized, but it wouldn't hurt to check.  Here's more info on authorizing your DHCP server:

I'll check that.  Browsing is working now.  I enabled netbios on the server.

Wow.  It wasn't authorized! I'm going to shut down dhcp on the router and test now.

:(  Nope.  Still can't get the server to do dhcp.

Hrrm.  Ok, does the scope actually activate (green up arrow in DHCP console)?  If it does, and it is now authorized I think you are really close.  Is your subnet mask correct?

I meant the subnet mask on the scope of course.  So we are missing something simple here, I think it is related to the scope.
What do you think?

Info on scope configuration:

Dang.  The client still can't get an addy.  Ok, so what client OS are you working with, just out of curiosity.

So on a client, if you set it to obtain IP config automatically and then do a ipconfig /renew what happens?

I think you will still have problems with your network because you are dealing with single label domain, what is your domain name something .com? I think after upgrade from NT4 you have to have just domain without.
That means your DHCP is not working, clients and servers will not register DNS seconds.
None of XP SP2 will register automatically DNS records, and DS doesn’t have SRV records registered, The whole concept of the domain is busted.

I think points to nihlcat, as it's doubtful whether or not this would have been fixed without his help !  :)

Tim, I'm new to EE.  It appears that I can't assign points to answers totallin less than 500, and I have to assign points to a specific answer which would be deemed the "correct" answer.  How can I assign someone partial points after finding my own answer?

I created the CNAME Alias for the server but when I got to network neighborhood I type:
\\serveralias

But it says Cannot find server \\serveralias.
But if I type:
//serveralias

I get a web page saying under construction. So the alias seems to be working but its not redirecting browsing traffic. Is there any way to do this?
