We have to set this while installing the AD through the DCPromo command. I was not working here when the previous administrator installed this Active Directory, so I don't know the Restore Mode password. Can you help me to reset it?
In Windows 2000, use the setpwd command as described here . For Windows 2003, you can use ntdsutil as described here. To automate setting the DSRM password across multiple domain controllers, go here for a script written by Directory Services MVP Dean Wells that will automate the process.
