Do you have another DC ?
Do you want to get rid of the entire domain ?
In extreme cases you can use DCPROMO /forceremoval

Normally, you'd simply run the DCPROMO command to demote the DC.  This will remove AD from it.  If for some reason this does not work, or if the server is not able to boot normally, check this article:

we moved over to a new domain, and are decommissioning the old dc , and leaving it as a file & print server

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

 
DrDave242Commented:
Once you're sure you no longer need the old domain, DCPROMO the DC.  It will ask you to specify whether it's the last DC for the domain (at least, I think 2000 did that - I know 2003 does).  Check the appropriate box and let the wizard do its thing.  If you run into trouble, post any errors or inconsistencies that you encounter.

DrDave242Commented:
Do you still have a DNS server configured for that domain?  If not, you'll need to install DNS on that DC and create the appropriate zones in order for it to be able to resolve the domain name and/or locate the necessary SRV records to identify itself as a DC.

right, big problem


i ran DCPROMO /forceremoval, server re-booted, now i can't log onto the server, in hindsight i should have created a local profile, but i didnt , is there any way of getting onto this machine?

As the machine is not on the domain anymore you need to use the local administrator password - not domain admin. If you can't remember it use http://home.eunet.no/pnordahl/ntpasswd/

i am guessing your server wasnt looking at itself for DNS - thats usually why you get those errors - still, the old demolition trick usually works too..
