I have 6 computers, all of which have Windows Server 2003 Enterprise Edition on them. I built a domain called JL_JL with a domain controller on one of my computers, which I can promote the other computers to be additional domain controllers. Here's the problem: I tried promoting one of my computers to be a domain controller, but I kept getting an error saying, "The specified user already exists." Any ideas how to fix this problem? Or what's going on? Thanks in advance!
