On Windows Server 2003, the setpwd or NET USER trick won't work. Here, if you want to change the Directory Service Restore Mode Administrator password you'll need to use the following method:

1.                  Click, Start, click Run, type

ntdsutil

and then click OK.

1. At the Ntdsutil command prompt, type

set dsrm password

1. At the DSRM command prompt, type one of the following lines:

To reset the password on the server on which you are working, type

reset password on server null

The null variable assumes that the DSRM password is being reset on the local computer. Type the new password when you are prompted. Note that no characters appear while you type the password.
or
To reset the password for another server, type

reset password on server

where is the DNS name for the server on which you are resetting the DSRM password. Type the new password when you are prompted. Note that no characters appear while you type the password.

1. At the DSRM command prompt, type q.
2. At the Ntdsutil command prompt, type q to exit.

You can now use the Administrator account to log on to Recovery Console or Directory Services Restore Mode using the new password.
