Can’t login to Win2k Server

In the process of setting up a new domain controller, the dcpromo utility asked to remove all local accounts, I answered “yes”.
Then it asked and confirmed an administrator’s password, and domain information etc.
At the end it asked to reboot, I sadi “yes”.
Now after reboot it does not accept any login old or new.
It is completely lockedup. Does not take even local machine login.
Any suggestion or help will save my job.
