How do I demote a DC that has already been removed from AD?

So here's the scenario...we had a remote site go offline with network issues due to local ISP problems.  They have a win2k3 DC there that was slated to be demoted anyway, however since the remote site went offline early and was brought back up on a different subnet for a couple of weeks they decided to go ahead and remove the DC from AD using ntdsutil.  

Now they have the new router installed and the DC is pingable again, but when i remote in to demote it can't find another DC on the domain with its computer account because its already been wiped out of AD.

My question is simply is there a better solution to demote it other than using this:

Hi,

As you already removed this DC from the Active Directory using ntdsutil, it doesn't have any existence in the domain. Best way is to backup all data from this DC and reformat the system drive. Using the ntdsutil to remove a domain controller is always the last option and it used in case of complete hard drive failure.
The thing is if you have already lost some FSMO roles you may have to use the ntdsutil to force distribute all the roles that belonged to the DC in question here.

Just the answer I was looking for, this machine was only there as a DC for authentication purposes but did have a good bit of application and data responsibility, formatting the OS was not an optimal solution, /forceremove worked like a champ.
