This might be a simple question, I'm not sure.
I'm pretty far along converting an NT4 network to 2k3. I've now got all the workstations and user accounts and home directories on the new 2K3 servers, which are DCs on a new domain.
I still have my original NT4 server and the old domain running because I have yet to take the last step, moving Exchange. That is, Exchange 5.5 is still on the NT4 PDC. Outlook on users' machines, even though on they are otherwise on the new domain, point to Exchange on the old domain.
All that is background. My question is about WINS. On the old domain, the PDC was (and is) also a WINS server. When I complete the migration of Exchange and decommission the old domain and its PDC, will I still need a WINS server? That is, is WINS completely done away with by Server 2003 and AD?
My workstations are all 2000 Pro or XP Pro, and (2) there is a SonicWall SOHO2/50 firewall between my network and my Cisco router, and (3) I'm using static IP addresses, if any of this has any effect.
