I am working with the following scenario:
Server 1: A very old Windows 2000 server that is a domain controller, print server, Anti-virus server (needs to be replaced ASAP)
Server 2: Another somewhat old W2K server that is the other domain controller and file server
Server 3: A new W2K server w/ Exchange 2000 used as the mail server
I want to replace server 1 because it may die any day and I don't have any support contract on it. I just found out that the server I purchased IBM e-Server 325 (Opteron based) only supports W2003. I'm thinking, I could introduce the new server as a w2003 member server in the domain first. Move the print services and Anti-virus server to this server. Then run ADprep and promote it to a domain controller and remove the old W2K server. I don't want to upgrade Exchange 2000 right now as it is on a fairly new server. My question is: can I keep Exchange 2000 and still introduce a W2003 server and promote it to a domain contoller by running ADPrep?
I was also thinking, perhaps, I could upgrade server 2 to W2003 (in-place upgrade), run ADprep to upgrade AD to 2003, then do a clean W2003 install on the new server as a domain controller, then make the new server a file server and get rid of Server 2 since I only will have one W2003 license.
Please let me know what you consider the best course of action. Thanks for your advice, conmments in advance.
