active directory help

[seamus19]

I need some help with the active directory replication On windows 2k server.
I am adding a new domain controller to a domain this will be replacing the old domain controler. I want to keep the same name of the old server for the new server. Here is what I did:
old server name testserver1, new server name testserver2
both on same domain. AD seems to be running fine however I need to change testserver2 name to testserver1 and remove the original testserver1 from the domain. Here is what I did:
dcpromo down testserver1 to member server and change name to testserver3 then dcpromo up. Remove testserver1 from DNS.
Then dcpromo down testserver2 to member server and change name to testserver1 then dcpromo up.
I then want to remove testserver3 offline, remove it from domain. However once I do this the new server which is now call testserver1 cannot see AD. It still needs the old server in order to see AD.
I have done this already and had to recreate all 1300 accounts and rejoin all 2k workstations, a very long process.
I need to do repeat the same procedure for another domain (replace DC)
and I need help. I want the second DC (new-DC) to see the AD after I remove the old DC. Any suggestions please I really don't want to have to recreate all accounts again.

Don't forget that you have to add testserver1 to DNS again, since you removed it......

It sounds like you should make sure all the fsmo roles are on server1. Make sure testserver1 has all the roles before demoting testserver 3. You can transfer the roles from server 3. If some roles are not located on 3, they may have to be seized...... using ntdsutil

To see who has the roles or transfer them ...

Go to AD users and computers and open it..
Right click on active directory users and computers[yourdomain]
Select Operations Masters

For the Domain Naming Master ...

Go to AD domains and trusts and open it
Right click on ad domains and trusts[yourdomain]
Select operations Master

For the domain Schema Master ...

Go to AD Schema MMC and open it
Right click on AD Schema [yourdomain]
Select operations Master

Note: The Schema Master and Naming Master are both on only 1 of the machines in the forest, whereas the other roles are located in each domain.
