How to remove active directory from a DC if it can't locate a DC to validate the admin PW?

I have a single Windows 2000 server that I installed active directory on, it is the only domain controller (and indeed, the only computer) in the domain.  I'm having DNS headaches because the domain name I used is used by my website off at a server farm somewhere, so DNS says the domain exists there instead of pointing to my DC.  Because of this, the DC doesn't recognize itself as a domain controller for that domain.  I tried setting my DC to use it's local DNS server, but for some reason a DNS zone for the domain wasn't created there when I set active directory up, so that didn't work.

Basically, I just need some way to convince the DC that it is a DC for it's own domain.  I tried using the hosts file with no success.  Any ideas?

Demote your DC by running DCpromo.

Reboot.

Rerun DCpromo taking the option of first DC in a new forest. This will install a working AD. If you do not have access to the internet, the process will create a root zone (signified by a dot) in the DNS forweard lookup zone. If it does this, delete the root zone and reboot.

In you dns entries, put an entry (under the correct forward lookup zone of) www.domainname.com to point to your web server. Do the same for any others, and everything should work (*MNIne is setup this way)

ALternatively, When you run DCpromo for the second time, use the naming convention of domain.com to domain.pri. Then follow thorugh on the rest of the process.

Please repost if you need more details

Sorry, I should have clarified that I cannot run dcpromo to demote to a standalone server because in order to run dcpromo, you have to provide an account with enterprise admin privileges.  Since the server cannot see the domain, it can't validate the account and dcpromo won't run.  I did some more googling and found a reference to dcpromo /forceremoval.  That removed AD from the system, but now I am having additional problems after reinstalling with a bogus domain name.  I think i'm just going to have to format the system and start fresh.

Wipe the box and start afresh. When you build it, do not connect it to the LAN. When you run dcpromo, set the DNS to point to iself. WHen it all works, reconnect the serve to the LAN.

This way DNS will work
