I have a client who has 3 servers in their Windows 2000 Domain. The domain controller is currently running Exchange 2000 on it. The current server is old, and Exchange is approaching the limit, so I am replacing the single DC with two servers: one server will be a dedicated Win 2003 DC, pretty much nothing else on it maybe some file shares, the other will be an Exchange 2003 server.
What should I upgrade first, the Domain or Exchange? Any recommended articles? The existing Windows 2000 DC will not be upgraded to Windows 2003, if anything it will just become a file server. Do I have to demote that machine after the domain is upgraded to Windows 2003, can you do that with Exchange still on it?
