Domain failure

[Guest]

I am a student that is repairing the domain for my computer repair. the
domain that existed before i attempted to fix it had 3 DC with 1 holding the
FZMO's and the other holding the global catalog. these two DC were removed
before transfering the roles and moving the global catalog. you could still
log on with some computers but not others. I am currently reinstalling
windows server 2000. This question is for the future in case this problem
surfaces again. there was 1 subnet 255.0.0.0 and the dc ip address is
10.0.0.1. I also could not demote the domain controller because it told me
that the domain did not currently exist.

If this one DC is still avilable (you told that You are currently
reinstaling Windows 2000 - I don't know, maybe You are reinstalling this
DC) seize the FSMO roles on this server

Then make it also GC and then remove from the AD other DCs entries using
procedure from this KB:
