Promoting secondary controller when primary controller has been rebuilt.

Our primary domain controller has been rebuilt and was not demoted prior to the rebuilt  and now we are unable to promote the secondary to primary status. When attempting to join the rebuilt primary controller it gives the  error: "The specified user already exists"

What steps are required to promote the secondary controller to primary status since the primary does not exists?

Hi

Can you give more information about what your domain structure is like? Is this a windows 2000 server domain ? Do you have an existing dc or dc's that are part of the domain prior to removing your main dc?

If so then it sounds like you've got rid of the server that held perhaps the bulk of the fsmo roles, in which case you'll need to seize those roles on the existing dc, and then remove the now non-existent dc from active directory. First determine which roles, if any are still held by domain controllers that still exists on the domain, then seize those roles held by the dc that you have lost.

Once you've successfully seized roles then remove your extinct dc from active directory:

Be careful using adsiedit if you need to use it, and I'd have a good backup of your existing dc first. Make sure that you have dns running on your existing dc, and you may need to make it a global catalog server if no other exists on the domain,
