I have a customer who is very concernd about migrating his NT 4 domain to
2000 Active Directory. The concerns are mostly due to the various 3rd party
software packages that they have running - some on the existing DCs.

I plan to install a clean NT 4 BDC in the domain and then promote it to the
PDC. I will then upgrade it to Windows 2000 and active directory. It will
be the first 2000 DC.

We also have two Windows 2000 member servers in the 4.0 domain. I plan to
use DCPromo on these to give us additional DCs. I will still have 4 NT 4
BDCs on the network including the original PDC that was demoted by my first
step.

My question is this. What if, for some unknown reason, I have to remove
active directory and go back to a pure NT 4 environment? At this point I
believe I could DCpromo the two additional DCs back to member servers and
take the 1st DC that was upgraded off the network. I would lastly use Server
Manager to promote my original NT4 PDC back to the primary DC.

Am I correct in my thinking? Since I never touched any of my 'original'
domain controllers I believe I would be back where I started.

Any input would be appreciated.

Thanks.
