Questions about adding a new 2K3 DC to a 2K Active Directory environment

Last Modified: 2010-03-17
I have an existing network with Active Directory running on 2 Windows 2000 servers.  I have just received a Windows 2003 server and have joined it to my domain.  I plan on installing Exchange server 2007 in a few days or so on this new server and phasing out an old Exchange 5.5 box.  I would like to demote one of my current DC machines and add the 2003 server in its place as a new DC for the existing domain.  Are there any problems introducing a W2K3 server as a DC to an existing 2K AD environment?  Will the 2K3 server automatically assume the necessary roles in this scenario?  Will it play nicely with the other 2K DC and XP clients?

That's a good plan. You need to prep the 2000 domain before you promote a 2003DC into it, but MS has an article on this (I tihnk running DCPROMO on a 2003 box in a 2000 domain tells you as much). Here's a link to the same Q elsewhere in EE

Thanks.  I'm taking The_Kirschi's answer for the insight into Exchange 2007 requirements, but I do appreciate your link, Garage.
