I have a 2003 server with all of the updates.  I have a new server that I
juat installed 2003 R2 on.  I am trying to install it into the tree, and get
the following 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."

I have ran Adprep /forestprep, adprep /domainprep, and adprep /domainprep
/gpprep on the old server, and still get the error.  What can I try?
