Upgrading Server 2000 to 2003, in a Domain that has 2003 servers running AD in 2000 native
Posted on 2006-06-05
This seems confusing and I can't figure out the logic behind why the previous Admins did this. I'm one of the admins that is running a mixed server 2003 and 2000 network. Active directory on the 2003 Domain Controllers is running in 2000 native mode.
I've run adprep /forestprep from the schema master and get this message
"Forest-wide information has already been updated"
when I try to run adprep /domainprep I'm told
Domain-wide information has already been updated.
So I go back to the computer I'm trying to promote to a domain controller and run dcpromo I get the message window
"The operation failed because:
The Active Directory Installation Wizard cannont continue because the forest is not prepared for installing Windows Server 2003. Use the Adprep Command-line tool to prepare botht 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.""
Which is where I'm lost, because I Ran Adprep, and it did nothing.
Any Guidence is very appreciated.
