The security database on the server does not have a computer account for this workstation trust relationship

I have a brand new SBS2008 and I accidentally deleted a computer account thinking it was an old one.

The client computer is a Windows7 x64 machine.  When I set up the computer originally, I created a default administrator userid and password for the machine.  Evidently, the user has either deleted this account or changed the password.

So, I can't get into the computer at all now.  

Tried manually creating the computer account through AD Users and Computers, but it's still telling me that the security database does not have a computer account for this workstation.

You must create a new local account on the machine with Administrator rights, then disjoin the computer from the domain and take it back to a workgroup.   Then rejoin to the domain using the http://connect utility

The machine still has the SID of the old computer account

Can you logon to the machine with the Domain Admin account?

Yes, I'm the network admin.  I can log in - I created a new computer account with the same name, but it's not taking.

OK, I was able to get the computer back online by using my UBUNTU x64 bootable USB drive along with the utility chntpw to reset the local admin account, then rejoin the domain.

Instructions are here:

The expert answer was partial - my main problem was that I needed to reset the admin password in order to get into the computer to rejoin the domain.  I was able to find the answer to that myself, but the expert's answer allowed me to join after I got back into the machine.
