It's been a while since we did that here in the college of business. If memory serves me correctly, we did a new server, ran DC promo, and then transferred the FSMO roles, and made one of the new servers a global catalog server. It wasn't as bad as going from NT 4 domains to Active directory.

I have a new server with Windows 2003 and I want to make it the domain controller. The 2003 server is brand new, I haven't even turn it on. I had been reading what I found available in the internet about a 2003 taking over a domain from a 2000 but I would like to listen stories or experiences of people who went through this transition before. I am sure that many of you already did it. According with what I had seen, it seems to be an straight forward procedure, but you never know and I would not like to make my network go down. -- Oscar Castaneda Michigan State University
