Active Directory: Reset the DSRM password in Active Directory

If you are still able to log into the server through normal operation, you can reset the DSRM password using NTDSUTIL. See http://support.microsoft.com/kb/322672 for Windows Server 2003.

If you cannot access the server in normal mode, you will need to use a hacking tool to reset the DSRM password on that server. Try using a tool such as http://www.ubcd4win.com/ or http://www.hiren.info/pages/bootcd.
