We have a 2003 domain with 2 DC, I am trying to dcpromote my 2008 member server to become a DC, it said to run adprep /forestprep but it comes up saying I can't do this on windows 2008, I need to do it on a DC controller. How to dcpromote it? thanks

I did do it and restarted both my Windows 2003 server, did the promote again on the Windows 2008 server still coming up with the same saying I have to forestprep first.

You don't do the promote on the 2008 unit, but the 2003 one. Never let your sense of morals get in the way of doing what's right. - Isaac Asimov
