NT4 to W2K3 DC migration

Hi All -

We will be migrating our NT4 domain to W2K3.  The approach, so far, will have us introduce the new W2K3 DC as a BDC.  My question has to do with DNS.  Currently, we have another server (separate from the NT4 DC) as the primary server.  Do I need to install DNS on the new W2K3 server and point it to itself to properly create the zone?  Or should I use the existing DNS server running on NT4?

Thanks in advance!

You cannot use a 2000 or 2003 server as a BDC in an NT network.   If you want a 2000 or 2003 DC, it the domain must be upgraded to Active Directory.

Yes and No (in that order).

For Active Directory to work the DNS needs to support Dynamic Update (NT doesn't, 2000 / 2003 do).

Adding a Primary Active Directory Integrated Zone on the 2003 DNS Server will add a zone which allows Dynamic Update and stores the Zone Data in Active Directory.

leew is absolutely correct about the BDC part, and you should cover as much documentation as you can for this.
