The way to mitigate that risk is to install a BDC into the NT4 domain, let it replicate then shut it off. If anything goes wrong with the migration then you can scrap the upgraded PDC and bring this BDC back online, promote it to PDC and be back where you were before the attempted upgrade.
I think Jorge also mentioned this in his very comprehensive message on upgrading an NT4 domain.

That will upgrade your domain and bring over all the good things in it now with users etc. It will also bring over all the problems groups, users, security issues, etc but nobody ever talks about that side of it. James R. Day Active Directory Core Team Office of the Chief Information Officer National Park Service (202) 354-1464 (direct) (202) 371-1549 (fax) [EMAIL PROTECTED] I have been asked this from a friend of mine and wasn't sure of the outcome even though I have told him not to go ahead. I was just interested in the implications and whether it can be done. He has a customer with an existing NT4 domain one PDC that's it. He has bought a brand new box and installed W2K3 dcpromo'd the thing and set up users, thinking he could just add the box to the existing domain and everything would be okay to migrate the users and data over. I know this sounds pretty crazy, but it got me thinking what would the implications of doing this and what is the best procedure for him at this stage. If any.
