Well if the DC crashed like you said, the domain doesn't know that DC is gone.
If you want to use the old DC name just reset the Computer account of the OLD DC in Active directory users and computers And than try to promote the DC,
If you want to use new computer name :
1. Remove the old DC computer name from the AD.
2. Remove all the information of the old DC (DNS,metadata, etc..) see http://support.microsoft.com/kb/216498
3. seize FSMO rules : http://support.microsoft.com/kb/255504 (you said you have another DC :) )
4. Promote the new DC with a new computer name..

I apologize for not doing my homework first, but I'm in a pickle and need help fast.One of my domain controllers (which held all the fsmo roles) crashed and I had to reinstall.Now that I've reinstalled, I'm ready to rejoin and promote. But I can't; I get "User already exists" when trying to join.I am using the same computer name as before. I have not deleted or changed anything in the directory on the other server yet.What do I need to do to get my old server back as a domain controller?Links to articles or even words to search by would be of great help.Thanks for any advice.Bruce.
