Upgrade Question

Hello:

Planning to finally pgrade our NT 4.0 domain to 2000. All servers and
clients (except PDC and BDC) are running windows 2000. In my present
environment, the Exchange 5.5 server is running on our BDC. My plan is to
upgrade PDC to 2000. I will then bring up a fresh install 2000 server, join
domain and install Exchange 2000. Install ADC and then run in mixed mode for
several days while we get the mailboxes moved over. I do not want to upgrade
the BDC. Once all mailboxes are moved over, we will just bring it down and
retire it.

Constructed a lab environment to mirror our production environment. The
upgrade of our PDC goes fine. We upgraded lets say from domain40 to
domain2000.com However, when I go to run dcpromo on another wiondows to 2000
server, it will not see the new domain (domain2000.com) as an active
directory domain. DNS and everything is in place. If I shutdown our BDC,
then and run dcpromo on one of the other 2000 servers, it sees
domain2000.com no problem.

I thought it was possible to run in mixed mode like I planned to do. Can
anyone tell me what I am missing?

Thanks
