I currently have a Windows 2000 DC and am trying to install Active
Directory on a Windows 2003 R2 server as an additional DC in the
Using the Windows 2003 R2 installation CD I have run adprep /
forestprep and then adprep /domainprep /gpprep on the Windows 2000 DC
to update the schema but I still get the error :
The operation failed because:
The Active Directory Installation Wizard cannot continue because the
forest is not prepared for installing Windows Server 2003. Use the
Adprep command-line tool to prepare both the forest and the domain. For
more information about using the Adprep, see Active Directory Help.
"The version of the Active Directory schema of the source forest is not
compatible with the version of Active Directory on this computer."
Any Suggestions ?
