Hi,

I've been searching thorugh other answers here, nuit still ma notr 100% sure if we can docwhat we want :)

We have an old NT 4 domain.  Hardware is old and not really able to to be upgraded to win 2003.  We wnat to migrate the NT 4 domain to be an AD domain.  The company want to keep the same domain name.  So is it possilbe to build the Win2003 Server on a new machine, then use PDC emulator (hope I've understood the purpose of the emulator?) to add it to the existing NT 4 domain, as a domain controller, so we can then get all the accounts, etc migrated to it and then turn off the old NT 4 PDC and then migrate all the other NT 4 machines over in simiiar manner?

Or do we have to create a brand new domain with the new machine and then use another tool to migrate all the account details across from the old to the new domain?

Thanks,

Neil.

If you want to keep your old domain name, you need to upgrade your current domain. Basic approach: Get new hardware, install NT4 as a BDC for your current domain; do a full replication. Promote your new BDC to PDC. Shutdown the old PDC (now BDC) as backup. Upgrade your new PDC to W2k3.

Here's more information:

Appreciate the clarification.  Another related question:

Once we have done the above, in installing 2003 on an existing NT 4 server and promoted it, am I right in thinking, that then make all the other NT 4 BDC redundant?

Not necessarily. As long as your new W2k3 domain is still running in mixed or interim mode, the BDCs will still replicate with the W2k3 DC, and they will continue to server logon requests from NT4 clients. As for potential W2k or XP machines, that depends on the NT4Emulator setting described in the last article (if you plan to use it, create the entry *before* the upgrade!). While the entry is set, W2k and XP clients should continue to use NT4 BDCs as well. Once it's removed, and the clients have noticed that they're now member of a W2k3 domain, they will only logon to W2k(3) DCs.
