DNS problems with DHCP server.
I have some older windows 2000 networks running around that are being upgraded to windows XP. These networks are all domains with DHCP on the server. Our internet access is usually cable or DSL service on a separate router.
What is happening is this. When the new windows XP machines logon into the domain it is very slow. It is so slow. Takes a few minutes just to logon onto the domain. The older windows 2000 machines are normal and log in very quickly. I know this is a DNS problem but don’t understand how to configure DNS properly. I have always been confused when a window 2000 asks me for the domain name and I don’t want it to think it is an actual .com domain. I need these servers to point at the DNS servers from the ISP while at the same time the windows xp workstations properly point to the server so they can logon quickly.
I need to understand DNS on windows 2k and 2003 boxes a little better so I can deal with this problem. Any suggestions on where to start?
