You can actually get stuck in a similar situation with MSAD. There is a
web page on microsoft about that http://support.microsoft.com/kb/216498
. I had once to dig into that with a dead DC that wouldn't leave my
win2k DC alone.
I'd advise you to use ApacheDirectoryStudio instead of adsiedit to
remove the old entries from your AD, it is much more user friendly. Be
sure to have a good backup before fiddling with your ldap entries!
Then use your dnsmgmt.msc to check and remove all the DNS entries of the
old DC servers (NS and SRV fields).
Hope this helps,
