I am trying to promote a Windows 2003 Server Standard box to be a backup DC for a Server 2008 AD.

When running DCPROMO on the 2003 box I receive an error reporting that it is not compatible with the current OS/AD levels of the primary DC.

I've tried performing ADPREP on the 2008 machine with results reporting that ADPREP has already been run/performed.

So the question is how do I make a Server 2003 machine part of a Windows 2008 Server AD?

I really appreciate your time and advice. :smile:
