Delete a tree from a forest, or recreate the first dc

I have a forest that has 2 domain trees. I demoted and took the only DC in one of the domain trees off line, and went about my way thinking that everything was good.

Now I want to recreate the domain tree, and I have found that the old domain is still listed in the AD. I want to recreate this domain tree but cannot because AD still thinks it's there, so if I try to create a new domain tree in my forest it gripes because the name i intend on using is currently in the AD.

How do i either get rid of the entry in AD or force it to allow me to add this machine.
Any help would be appreciated

Did you Demote it or Take it offline?

If you demoted it online, the Forest would know you did this and it would likely not give you the problem you are having.  

If you took it offline and then demoted it, or blew it away, you may be able to rebuild it (Same name and same NIC card) and plug it back in.  If you need to then change the hardware, demote it while connected and be sure to click 'Last Domain Controller' while running DCpromo.

I have removed 2 Child domains from my forest and this worked fine, I then added the DCs back into the Forest Root domain with the same name.

I demoted it then took it offline as I stated in my question, I know that it should work correctly that way but it did not, which is why i asked how to fix it.. :)

i have removed other domains from teh forest without issue but for some reason this one doesn't want to leave

you'll have to use the ntdsutil.exe tool to clean it up.
