Changing Domain Name 2000 2003

am in need of your advise please.
Our Domain Name has changed to, the reason for this is the owner of the domain name has moved the domain and will not give us access to it.

So of course we have lost our website and email.
we have already registerd our new domain
We now must do the DCs here. Of course the easy way is not available
Which is the 2003 Rename tool because we have the DC 2000 server. GREAT!

My plan of action is as follows please advise if you have another solution
What we must do:
1.      Backup the Entire Domain
2.      Setup KHSDOMAIN2 As the main DC GC
3.      Remove KHSDOMAIN DC
4.      Give Authority to KHSDOMAIN2
5.      Promote KHSDOMAIN3 To Global Catalog Server
6.      Retire KHSDOMAIN
Then I can start on the Domain Rename which requires
1.      Generate Current Forest
2.      Specify new Forest
3.      Generate Domain Name instruction
4.      Push Domain Name Instruction to all DC
5.      Verify Readiness Of DC
6.      Execute Domain rename
7.      Unfreeze the Forest Config
8.      Reestablish External Trusts
9.      Fix DFS Topology
10.      Fix GPO
11.      Prepare URL For CDP
12.      Update DC Certificates
13.      Change User Identity
14.      Restart Member Computers

Hello joseph98310,

Your AD domain name is semantic in that it has a meaning to you (of course there are some DNS issues to work with). A domain rename is not trivial and if you have exchange server installed you can forget it - you will be troubleshooting for some time, and it is not supported. Though it is not entriely clear if you have exchange the point remains - why must you do this?


joseph98310Author Commented:
We do have exchange this is the primary reason. Without this domain change we will not recieve any email of course.
Are you saying that since it is exchange forget it we will need to reload all?
Good information, but was hoping this was not the answer.
James MontgomeryCommented:
No, the exchange smtp domain is not the same as your Active Driectory domain - or at least it does not need to be.

With exchange the change you need is rather minor to accept mail for the 'new' domain :D

Excellent suggestion and it worked like a charm to do changes with Exchange. Now the preoblem still remains, no one is recieving emails with our new domain name. Even internal still deafaults to the original domain not the new.
DC = Domainname.Org
Excahnge =
Old Email =
new email=

I have updated MX records for

The big question is why when my users login they still have the old email address instead of the new one?
James MontgomeryCommented:
Lets get some things clear.

When you send email out - do the recipients receive this and see it comming from the old or new domain?

Did you make sure the new smtp domain becomes primary or default for users and that it has higher priority than existing default policy?

To check open user properties and see which email address is in bold - this is the primary.
