Client has two domains and wants there only to be one. Domain A's DC is an sbs2k machine, and Domain B's is a 2k3 running at Windows 2000 Mixed functional level. Along with changing the domain name I will need to change the computer name as it is identical to one already on domain A. I read that it's required to change 2k3's functional level to 2003 in order to make name changes changes using netdom. So I believe I'm unable to carry out task without a clean install. What can I do?

I would suggest your best option is to demote the DC in domain B, rename it, join it to domain A and then promote it to being a DC in domain A.

Otherwise, even if you are able to change the name, you are still going to have issues with that machine being a DC in domain B. Do it properly first time and you will have less issues in the long term.

You can only raise the domain functional level to 2003 if all domain controllers are running the 2K3 OS.

You'll need to do a clean install of 2K3 on Domain A and dcpromo it.

  • My bad, forgot to clarify on that in the question. I did already know that having to change the functional level was not going to work having the sbs2k DC. Thanks though! – Daniel Jan 25 '11 at 22:23
