Ok, i've got a DC running Win 2000 SBS and it's running exchange 2000. I bought a brand new server and want to load 2003 SBS on it and promote it to the primary DC and take the place of the current 2000 SBS. From what i'm readin, you cannot have 2 SBS DC's running in the same domain at once. Is that true? If so, what other options do i have besides creating a new domain and having to go around to 45 machines and change everything? Any help would be appreciated.
