Join 2003 Server to 2000 Active Directory Domain

I have an existing Dell Poweredge server running Windows 2000 Server SP4. I have another Dell Poweredge server now running Windows 2003 Server R2 Standard joined to the domain of the Windows 2000 Server. Everything rocks along fine. I can see the existing server, communicates fine. DNS is setup perfectly and replicated from the 2000 server perfectly.

I would like to now install Active Directory on the 2003 server and add it to the existing 2000 AD domain. However, I continue to receive the "the version of the source active directory is incompatible with the version on this computer" message. I have run ADPREP /FORESTPREP, /DOMAINPREP and /DOMAINPREP GPPREP and everything completed successfully but I'm still receiving the error. No errors in the event viewer. It just simply will not work.

Anybody have any ideas?

    R2 has another prep you have to run (I've not had to do this myself yet).
