I have a Windows 2000 native domain and Windows 2000 Forest & Domain controllers. I also have Windows 2003 servers that are not DC, just members of the domain like any other computer.
I am purchasing Windows 2008 Server R2. I want my forest and domain to be the latest AD.
Originally, the domain was NT 4.0 and we upgraded to 2000 way back when. It was never quite "right" in that some old references were kept to an even older domain and things like Policies don't always do right, I have a lot of GPO errors on the computers about not being able to import GPOs...etc.
Do you think I should try and upgrade my forest and domain by upgrading the 2003 servers to DC and then upgrading the forest and domain to 2008?
Or do you think I should create a fresh new domain with new servers and try and transfer users, mailboxes (there will be a 2008 exchange server as well), and other AD settings to the new domain?
