Question
DC Name Change
Hello,
We had to do an emergency repair on a DC (Windows Server 2003 SP2) about a month ago. It was one of those middle of the night fixups where the best answer was keep the same IP but rename the server with a new name. Now we'd like to rename our stable server back to its original name since it follows the naming convention used by all of the other DCs in our domain (and many of our legacy login scripts). I understand I have to do a dcpromo down to demote it, rename it and then dcpromo up with the new (old) name. My question is since this is one of many DC's in our domain, when I log back into it after demoting it, can I still use my domain admin credentials ? As I understand it, demoting it doesn't take it off the domain, it just takes out AD so that it is just like any other server on the domain. This kind of stuff always needs to be done in the off hours (and this particular server is about a two hour's drive). Before I "press enter" and go for it, I thought it best I check to be sure!
Thanks for your assistance with my endeavor!

You do not need to demote the domain controller to rename it. You can do it through the GUI (system properties) or you can do it using netdom which a lot of people choose. I haven't used netdom myself or the gui method, but I have used the method of DCPROMO demoting first then waiting a while and cleaning up AD to ensure ebrything is talking to each other as they should. (yes you will be able to login with domain admin credentials and as mentioned, you will need to give a local admin password as it will be just another member server with it's own SAM database.
Using the GUI is quick, but it seems to take a while before users can see it and then authenticate to it, so it will be more impacting on your network and the users.
Netdom.exe on the other hand requires the Windows support tools being installed but provides a less impacting change to users apparently. You also need to have your functional level set to Windows 2003, so that may not be feasible in your scenario anyway
So you have a number of choices. See here for the alternatives http://www.petri.co.il/win
A big considration here is to ensure your DC's are replicating and also DNS replicating before you try too much. Patience, my friend, is the key! Good luck and keep us updated. cheers
Every domain has its own "personality". This one is no exception. With this machine so far away and the work needing to be done in non-production hours, the weekend makes the best choice. That said, the server was not deleted from DNS the first time; so, I had to manually delete it. It took a bit longer, and once the ensuing panic of it not working as I had expected waned, I got it done!

Hello,
Yes sir, demoting a domain controller will surely allow you to log in using your domain credentials unless if it was the last domain controller of course.
when you demote, you will be asked to enter the new local admin password since it will no longer be a domain controller, and you will be able to login using the local admin credentials and the domain credentials
