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.”
