    Resetting Administrator Password in Windows 2008/2012

    Nothing quite like not having the local administrators password on a migration! Here’s a quick reset method:

    Boot from the Micrsoft Windows Server 2008/2012 DVD
    From the Windows Setup menu, click “Next”.
    Select “Repair your computer”
    Under Choose and option, click on “Troubleshoot”.
    Under Advanced options, click “Command Prompt”.
    At the command prompt, run the following commands:

    d:
    cd windows\system32
    ren Utilman.exe Utilman.exe.old
    copy cmd.exe Utilman.exe

    Close the command prompt, remove the ISO and reboot the server.
    At the logon screen. Here click Windows Key + U or click the lower left icon.
    At the prompt you can now change the password, by typing the following command:

    net user administrator MonkeyMagic

    Net User - Cloud Monkey

    This will set the password for the Administrator user as above

    Worth checking that the local Administrator account is active or to see all local accounts:

    net user

    Once all done, don’t forget to be a tidy Monkey:

    d:
    cd windows\system32
    ren utilman.exe utilman.exe.new
    copy utilman.exe.old utilman.exe
