Re: Add WS 2003 R2 to a Mixed mode domain (NT 4.0)

You need to run adprep from (I think it's the second disk) the R2 disk on
the schema master for the forest.

I am in process of upgrading our old NT 4 domain to 2003 AD. The
existing PDC could not be upgraded - to many years of hacking on it by
too many admins. I built a new, temporary, NT 4 box as a BDC, promoted
it to PDC, did an inplace upgrade to WS 2003 (non-R2). There is still
an NT 4 BDC at another location in the same domain connected via a VPN.

Today, I tried to add the Domain Controller role to my new WS 2003 R2
box, adding it as an additional DC in the existing forest, but I
received the following:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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."
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

What do I need to do to get around this?
