net user administrator <new password>

Posted on 2011-10-22

I was setting up our new server as the Role of ACTIVE DIRECTORY DOMAIN CONTROLLER and the OS (Windows Server 2008 R2 Standard) popped up w/ a dialog box instructing me that I had to run 'net user administrator passwordreq:yes' b/c the local administrator account had no password.  I did this and when I tried to log back in, I had to use the password <passwordreq:yes> in order to successfully log in.  

I figured I would remove & re-add the Role as Domain controller and when the dialog box reappeared, I ran 'net user administrator <newpassword> this time.  Now I cannot get ANY previous, blank, or <newpassword> set of credentials to work.

I am at a stand still until I get this recovered.  ANY IDEAS on how to recover, or reset, the current password for Administrator? I have not yet created any other accounts and have no way of logging in.

Please advise...

    Another good choices are
    - Offline NT Password & Registry Editor
    - [Well known cracking CD comment removed by JustAMod]

    I've used Offline NT Password & Registry Editor (AKA ntpasswd) for resetting passwords many times. It's nice because it is free, and legal. Other options like Hirem's Boot CD have questionable legality.

    IT Is against EE Rules to advertise or discuss such programmes as oph*** as they are security cracking tools. They do not reset passwords they allow you to steal them!
