English Language Version

After you have installed the hotfix, you can use the Setpwd.exe tool (located in the %SystemRoot%\System32 folder) to replace the null password with a strong password. To do this:

1.    At a command prompt, change to the %SystemRoot%\System32 folder.

2.    Type setpwd [/s:<servername>] , and then press ENTER. Note that adding the server name is optional. This parameter is used only when you change this specific password on a remote domain controller.

3.    You will then be prompted to "Please type the password for DS Restore Mode Administrator Account:". Type the new password that you would like to use. If you make a mistake, run setpwd again.

 

 

How To change the Recovery Console or Directory Restore Safe Mode Administrator password on a Domain

http://support.microsoft.com/kb/239803

How can I change the Recovery Console or Directory Restore Safe Mode Administrator password on a Domain Controller?

 

When you promote a Windows 2000 or Windows Server 2003 Server-based computer to a domain controller, you are prompted to type a Directory Service Restore Mode Administrator password. This password is also used by Recovery Console, and is separate from the Administrator password that is stored in Active Directory after a completed promotion.

 

The Administrator password that you use when you start Recovery Console or when you press F8 to start Directory Service Restore Mode is stored in the registry-based Security Accounts Manager (SAM) on the local computer. The SAM is located in the %SystemRoot%\System32\Config folder. The SAM-based account and password are computer specific and they are not replicated to other domain controllers in the domain.

 

For ease of administration of domain controllers or for additional security measures, you can change the Administrator password for the local SAM. To change the local Administrator password that you use when you start Recovery Console or when you start Directory Service Restore Mode, use one of the following methods:

 

 

 

Method #1

If Windows 2000 Service Pack 2 or later is installed on your computer, you can use the Setpwd.exe utility to change the SAM-based Administrator password. To do this:

 

At a command prompt, change to the %SystemRoot%\System32 folder.

 

To change the local SAM-based Administrator password, type

 

setpwd

 

and then press ENTER.

 

To change the SAM-based Administrator password on a remote domain controller, type

 

setpwd /s: servername

 

and then press ENTER, where servername is the name of the remote domain controller.

 

When you are prompted to type the password for the Directory Service Restore Mode Administrator account, type the new password that you want to use.

 

Note: If you make a mistake, repeat these steps to run setpwd again.

 

 

 

 

 

 

 

Method #2

On Windows 2000, if you do know the Directory Service Restore Mode Administrator password you can easily change it to something else by using the following method:

 

Shut down the domain controller on which you want to change the password.

 

Restart the computer. When the selection menu screen is displayed during the restart process, press F8 to view advanced startup options.

 

Select the Directory Service Restore Mode option.

 

After you successfully log on, use one of the following methods to change the local Administrator password:

 

At a command prompt, type the following command:

 

net user administrator *

 

or

 

Use the Local User and Groups snap-in (Lusrmgr.msc) to change the Administrator password.

 

Shut down and restart the computer.

 

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

Method #3

On Windows 2000, if you do not know the Directory Service Restore Mode Administrator password you can easily change it to something else by using the following method:

 

At a command prompt, type the following command:

 

net user administrator 123456

 

This will change the local administrator's password to 123456.

 

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

Method #4

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:

 

Click, Start, click Run, type

 

ntdsutil

 

and then click OK.

 

At the Ntdsutil command prompt, type

 

set dsrm password

 

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 <servername>

 

where <servername> 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.

 

At the DSRM command prompt, type q.

 

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.
