You forgot the domain admin password? This article explains how you can reset the administrator password in a Windows Server 2008 (R2) and Windows Server 2012 (R2) domain.

First of all, you should never work with the “Administrator” account. Each admin should have his own account, for two reasons. First, it makes troubleshooting easier if an admin messes up. Second, if one admin forgets his password, another admin can reset it through Active Directory Users and Computers (ADUC). Whenever you reset a password, however, note that the corresponding account will no longer be able to access passwords stored in Internet Explorer or files that have been encrypted with EFS.

If you forgot the domain admin password, and no other administrator exists in this Windows domain, you can use the procedure below to reset the password. Note that the screenshots are for Windows Server 2012 R2 with Update. However, this guide also works for Windows Server 2012 and Windows Server 2008 R2.

With this password reset method, you have to boot from a second Windows installation. You then have to replace utilman.exe (the Utility Manager with ease-of-use functions such as the Narrator and Magnifier) on a domain controller with the command prompt (cmd.exe). Next, you’ll boot up the machine where you forgot the password, click the Utility Manager icon on the logon screen to launch a command prompt, and then reset the password. Here is the step-by-step guide:

  1. Boot from a Windows Server 2012 R2 DVD (or ISO file in a virtual environment) and click Next when Windows Setup loads.
    Windows Setup
  2. Press SHIFT + F10 to open a command prompt.
    Open command prompt in Windows Setup
  3. At the command prompt, enter:
    move d:\windows\system32\utilman.exe d:\windows\system32\utilman.exe.bak

    Note: On Windows Server 2008 R2, you will most likely have to replace the drive letter d: with c:. If you are unsure about the drive letter, search for the drive that contains the Windows folder. The driver letter for the instance of Windows PE that started Windows Setup is x:. (Update: As mentioned by Chidi, you can run the diskpart command and then on the displart prompt, you can enter the list vol command to get an overview of the available drives. The system drive should be labeled accordingly.)
    Move utilman.exe

  4. Replace utilman.exe with cmd.exe:
    copy d:\windows\system32\cmd.exe d:\windows\system32\utilman.exe

    Copy cmd.exe

  5. Remove the boot media from the server and tell Windows PE to reboot:
    wpeutil reboot

    wpeutil reboot

  6. Once your domain controller is running again, click the Utility Manager icon.
    Utility Manager icon
  7. At the command prompt that (I hope) opened, reset the domain admin password with this command:
    net user administrator *

    Reset domain admin password

  8. You can now close the command prompt and log on with the new password. However, mainly for security reasons, I highly recommend restoring the original utilman.exe. For this, you have to again boot Windows Server setup, follow steps 1-2, and then enter:
    move /y d:\windows\system32\utilman.exe.bak d:\windows\system32\utilman.exe

    (Replace the drive letter if Windows isn’t installed on the d:)
    Restore utilman.exe

  9. After you removed the boot media, you can reboot the server again with
    wpeutil reboot

    Password reset complete

Obviously, this procedure can be used by anyone who has physical access to your servers. In my next post I will give you a few tips how you can prevent the Utilman.exe password reset trick.

    Or you can use NTpassword

    Andrew, thanks for the tip. I am currently playing with the tool to see if it still works with Windows 8.1. However, I think you can’t use ntpasswd to reset a domain admin password because it only allows your to manipulate the SAM database.

    Hi again,
    I tried following this and it said it moved and copied the files but after rebooting and pressing the utility manager icon, it doesn’t open command prompt, it just operates as normal.
    This is a windows 8 tablet, so I’m booting off legacy to boot from a Windows 8 install disk and then changing back to UEFI so that I can boot back into windows normally, would that cause any issues?

    I didn’t try this procedure on a UEFI PC, but I doubt that this is the problem. It is more likely that you copied utilman.exe to the wrong location. Compare the file sizes of utilman.exe and cmd.exe and check if d:\windows\system32\utilman.exe has the size of cmd.exe after rebooting into the Windows installation where you forgot the password.

    Hi, my gf forgot her administrator password so I’m trying to reset it. However I can’t see any folders on the hard drive and I can’t go to the windows directory. Any ideas what is it that I could be doing wrong?

    philip, try a different drive letter.

    Hello Michael,

    This allows us to reset the password for a local user account. Do you have instructions for how to change a domain admin account?

    Carlos, it this for a domain account. It didn’t work for you?

    abdul, your Windows installation is probably on another drive. Try the dive letter c: instead of d:

    I tried doing this. D:\ is mapped as the CD-drive on this. Our professor has setup virtual machines for all of us and we had to install windows 2012 on them. I think we used a virtual HDD for this. Because bios shows – VMware Virtual SCSI Hard Drive (0:0). Im not able to find system32 on any drive except x:\sources\windows\system32 but when i use that, the cmd doesnt pop up on reboot.

    Please help!

    Will this method work with Windows 8. Will I loose any files because I locked my father’s domail connected laptop.

    can yo explain what you have done in step 1 and how to get windows server 2012 and how to boot it.

  25. Avatar

    Tony, yes the method works with Windows 8. If you encrypted files with EFS with this , you will be unable to decrypt after resetting the password.

    tony, you can use any Windows boot medium. You can download the Windows 10 ISO and put it on a bootable USB stick. If you are not an IT pro, you better ask for help.
