My first thought is that if you're making the new machine a BDC, then
running W2K3 on it as an upgrade, it will automatically assume the "PDC
Emulator" FSMO role. This will in essence put two PDC's on your network,
which isn't good news, of course.
So first off, you're going to have to re-think this part. Your choices are
to promote your current PDC (take a BDC offline that's been synched up
before you do this in case things go way south) to W2K3, then you can just
load W2K3 on the new boxes and you won't have to load the OS twice on the
new, shiny servers.
*OR* make the new machine a BDC, take the old PDC offline and stash it away,
promo the new box to PDC, and THEN do the in-place upgrade.
The problem is that you're going to lose your DNS server if you do plan B
because you'll be removing the server running your DNS from the environment.
May want to try moving your NT4 DNS and WINS to the new box, then do the
above. Regardless, you're going to have to make a decision on waht to do
with your DNS/WINS box prior to doing anything with the new server.
This help?
