Active Directory

We hava a DC (Server 2003) in the Active Directory we are attempting to join another DC (Enterprise 2003 RC2) to the domain. I am receiving an error message that the Active Directory saying the forest is not ready for installing Windows 2003 Server. The version of the Active Directory in the source forest is not compatible with the version of active directory on this computer.  The commands  adprep /domainprep and  adprep /forestprep were run on the DC that is in the active directory.

Does anyone have any suggestions.

Thanks

You need to run Adprep from the  \CMPNENTS\R2\ folder on CD2 of the R2 disks on the existing server.
