This is not an easy task. With Windows 2000 AD, it requires a complete
domain rebuild. Just changing the names ain't going to do it. Maybe a
migration using ADMT and Exmerge would be the better route for you.
If you can upgrade to Windows 2003 and Exchange 2003 (with SP1), there are
rename tools available.
Maybe you can live with your current scenario. This is actually what is
called a 'split-zone', 'split-brain' or 'split-namespace'. What sort of
issues are you having? If just the fact of trying to get to their website
and/or send email to them, you can actually manually create the necessary
records in DNS so you can communicate with them. To get to their website,
you can create a 'www' record, and give it the actual external IP address.
This way you can get to their website. If you need to send mail to them, you
can create a 'mail' record, give it the IP of their mail server, then create
an MX record, pointing to that mail record. Make sense? I mention this
assuming that you are not using your internal domain name for external
public use and inadvertenly created your AD structure using their name.
