I have a Windows 2000 Domain Controller. The client computers are all members of this domain. The client computers are running either Windows NT 4.0 or Windows XP. I've recently added a standalone server running Windows 2003 Standard. Since then, my Windows XP PCs are having difficulty logging into the domain. The problem does not seem to be affecting the Windows NT PCs. I think the new Windows 2003 Server is trying to authenticate the login requests from the Win XP clients and can't. How do I stop the Windows 2003 Server from acknowledging the logon requests?
Unless you manually run dcpromo on the Windows 2003 Server to add it to your network as a domain controller, it is incapable of servicing client logon requests. Verify that the DNS records for your Windows 2000 Server and 2003 Server have been created correctly, since 2003 uses DNS as its default name resolution protocol.
