Cannot Join Win2k3 domain or access shares

Are you using static IP addresses for all of your computers?
If so, do you have the SBS server listed as a DNS server?

If you are not using DHCP - why not - then as has been stated you must make sure that your clients all have a valid IP and subnet mask and that the ONLY DNS server they have listed is the SBS server.

If you are trying to use DHCP on a router rather than the DHCP in SBS then I strongly advise against this. Switch off the DHCP on the router and set up your SBS server with an appropriate scope.

Yes, all computers have static IP addresses. DHCP was already running on the router (prior to me reconfiguring the server), so that's why I didn't bother with it on the server (although I did install the service I didn't configure a scope). So I don't think that qualifies as having 2 DHCP servers running on the network. I only have one DNS server listed for each workstation, and that is the server.

run ipconfig /all on both the SBS server and a client and post the results please.

In the meantime kill DHCP on the router - its safer to do if you don't intend to use it.

Make sure that before you join the workstation to the domain, that you don't have any drives mapped to the server on the workstation.   Map the drives after they are joined.

Sorry for the late followup, and thanks for all of your suggestions. I will post the IPCONFIG /ALL results later today, and yes, I'm aware of the mappings and made sure that none of the logins had any. In fact, I also tried a brand new workstation, which has never been connected (mapped) to a server.

On the workstation. (note that although this is a VMware environment, the configuration is not different on physical computers, and now a Windows 7 system.)

Can you map a drive to the server from the workstation?   Just curious what error it puts up if any.

Can you list which services are turned OFF on the server?   Did you turn any off during your setup?     Check on "Routing and Remote Access".   Make sure it is on.  

Routing is on, but cannot map - same error. Note that the one service that is not working correctly is WINS, even after removing and reinstalling.

No idea what caused all of this in the first place.

Sometimes you hit the point of dimishing returns the more time you invest.    It is the mark of experience to know when to make the call.   Good job.  

Precisely. Thanks!
