Client computer accidentally deleted in AD

I accidentally removed a computer from AD (stupid I know). So the problem is, I cannot logon locally to the client as the password is not known (also stupid I know). So I have a client machine that still thinks it is part of the domain, but it's not in AD. So it obviously cannot log onto the domain when it tries. Obviously, I cannot log on locally, therefore I cannot remove and rejoin the machine.

Is there anything I can do to get it back on the domain so I can at least log on to the machine or any other type of solution I can try or am I pretty much screwed???

Any help would be greatly appreciated.

You are going to have to change the admin pass using external software.  I use a Sysinternals Admin boot cd and use the Locksmith program to change it.  There are quite a few linux based book cd/floppy packages out there as well that work.

I'm assuming that you have tried the common admin passwords yet?  (blank, password, admin, etc)
