WIN2003 Server DC re-naming

Posted on 2006-03-20
Last Modified: 2010-04-13
Maybe i am missing something quiet obvious here, I have a DC which died yesterday and i have now got my hands on a new server now what i would like to do is have this new server play the role of the old one but if i go to rename it to what it was .. it says it already exists, (which would be correct) but i need it to be the same as its listed everywhere in our Domain forest,  do i have to remove this DC completly from the organisation first or is there a simpler way

any help would be much appreciated

    Sorry just to add to this .......
    this server is on a workgroup at the moment and if i try to "dcpromo" it i get this message ...

               The operation failed because:
               The attempt to join this computer to the "mydomain" domain failed
               "The specified user already exists."

    You need to delete any reference to the failed DC before adding a new DC to your domain with the same name

    Yep it is...

    Done it a few times in the past....

    If you don't do a cleanup you will certainly run into problems in the future.
    Check all FSMO roles and seize/move them to another server prior to the dc-de-promo process

    The cleanup itself is quite standard
