You sure you're not trying to add a 2K3 R2 server? I would expect that only if the ForestPrep was done with the older 2003 ADPREP. Maybe it needs to be in 2000 Native mode?

Use the Adprep command-line tool to prepare both the forest and the domain ...... "The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer." Three DCs at this site, all show proper replication, event logs show nothing relevant, attempt to rerun adprep show "Forest-wide information has already been updated " Anybody run across this before ???
