Can you create a new forest on your existing Domain
Controller or do you need another one?
I'm not following you here. When you add a NT 4.0 BDC to your domain and
replicate, your next step is to remove AD form all AD DCs. Then you promote
your NT 4.0 BDC to PDC and upgrade to Win 2k creating a forest/domain.
Your "existing" domain controllers at one point have Win 2k and AD on them,
then you add a NT 4.0 BDC, then remove AD from the Win 2k DCs. Now your
"existing" domain controller is the NT 4.0 BDC. When you promote, then
upgrade to Win 2k, your "existing" domain controller *should* be in the new
forest/domain you are setting up.
After the
migration are you back to a single domain or are there
still traces of the original left?
Removing AD by running dcpromo on all AD DCs will leave you with only a NT
4.0 BDC that you promote to PDC. You will have one domain.
Does the migration
affect the client PC's or just migrate the computer
accounts? Do you still need to change the domain on each
client PC?
I believe you have to join the PCs to the new domain.
