server rename during upgrade in mixed mode.

We have a mid size network of mixed servers 200+ located at multiple sites( 20+) . One of our remote sites has an older 2003 server that needs to be replaced. The entire AD is in mixed mode so we cannot change to native at this time due to some NT 4.0 applications.

We are replacing this remote site server with a bigger box. The older server being replaced is a domain controller but does not carry any of the FSMO roles. It does run dns, DHCP and wins for that location. It is also a global catalog server for that location.

Replication is used to this system from our corporpate headquarters servers.

My question concerns renaming the new server once we have it changed it over to the Domain Controller role at this site and transfered all the applcations and services to it. Since it is on the domain is in mixed mode I understand that it will prevent us from changing it to the old server name. What is the correct procedure for this changeover. Especially the renaming of the new server to the older servers name. Moving the Domain to native at this time is not possible.

Any assistance would be helpful Thanks

What do you mean clear any old references to the server. Do you mean the old DC server or the new DC server taking it's place. Several programs such as SQL 2000 will be migrated from the old server to the new one. Since I want the name of the old server on the new one will these programs be affected?

you need to remove any references from DNS, sites and services, ADUC, you can even run a metadata cleanup using ntdsutil if you think there might be any old remnants.

remember, same name, but it still has a new ID. as such, most references should still be ok
