New root domain possible for existing AD domain?
Posted on 2003-02-21
Hello! First-time user. Hope I'm doing this properly.
Let me first layout our situation, then I will pose the question:
I have a mixed-mode domain in Dallas which we will call texas.idiots.net. This domain was previously all NT4. When the PDC was upgraded, the mistake was made to designate texas.idiots.net as the root domain. I now know from reading other questions on this site that we should've first created a new domain with new hardware and designated it as just idiots.net, then upgraded the existing domain. Too late, so sorry.
Now, we also have a "sister" company in New Hampshire who was also running an NT4 domain with a two-way trust to our domain. Both of their domain controllers were upgraded to Windows 2000 and they were nestled into our existing namespace as nh.texas.idiots.net. I hope no New Hampies will be offended by that unintentional slight.
On a side note, just in case my upcoming question will be adversely affected by this, we have two Exchange 5.5 servers. One resides on a member server in the texas.idiots.net domain and provides email for users in the nh.texas.idiots.net domain. Why? I don't know. It was that way when I got here. Our other Exchange server resides in a wholly different yet trusted domain (a resource domain in the DMZ) which we will call dmz.fubar.net. This server provides email for the texas.idiots.net users. I will no doubt have more questions for this forum when we upgrade to Exchange 2000, which I've been told to have underway VERY soon.
Now the question: Can I create a new domain, with new hardware, containing only domain controllers, and designate it as the root domain idiots.net, then somehow have the other idiots.net subdomains "merge" into that root domain? I know that .NET will provide a namespace renaming tool, but we're light years away from that.
Or, if you have a better solution, I'm all ears.
Thanks in advance!
