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:

- Boot from a Windows Server 2012 R2 DVD (or ISO file in a virtual environment) and click Next when Windows Setup loads.
- Press SHIFT + F10 to open a command prompt.
- 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.)
- Replace utilman.exe with cmd.exe:
copy d:\windows\system32\cmd.exe d:\windows\system32\utilman.exe
- Remove the boot media from the server and tell Windows PE to reboot:
- Once your domain controller is running again, click the Utility Manager icon.
- At the command prompt that (I hope) opened, reset the domain admin password with this command:
net user administrator *
- 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:)
- After you removed the boot media, you can reboot the server again with
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.

Hi, Can you help me? My case is a bit different. I gave my personal laptop to install/ put on office domain. I quit my job. Moved to another country where I was given a domain connected laptop at my new job. Now its been years… now I dont remember my old login or password. I thought I could clean the laptop and give it to my young nephew just to play games…After all it has 6gb ram and 300 gb hdd. I have the original windows 7 key but it runs on Windows XP as per my previous domain requirements…I tried to log in with whatever left of my memory…it keeps saying “the system cannot log you on now because the domain **** is not availabe.” There are 3 option in “Log on to” drop down menu 1) intranet 2) domain 3) this computer. I tried logging in locally too but had no success. It seems the internal drive is also password protected. The laptop is rightfully mine but I have no Idea what to do with it. can you suggest me some way?
If the internal drive is password protected, there is not much you can do. You you can try reinstalling Windows, but if you don’t don’t have the BIOS password, this might fail. There are hacking tools for various laptop models that allow you to manipulate the BIOS. However, this is only something for geeks. Another option is to bring the laptop to the manufacturer support. They probably can reset the BIOS and then you can either follow the procedure described in this post or reinstall Windows.
You can try to unlock/force the local admin password using some tool. I suggest to take a look Hiren’s Boot CD. It is a well know tool collections that us a windows pe running on notable USB. It has also some passwords tools that can help you. For example you can use the NTPWedit and reset the local admin pwd. But as already explained by Michael, the hard disk password is more problematic and there is not an easy solution for this pwd.
Forgotten to mention the full link : Hiren’s BootCD
Hi guys, Thanks for the replies. Mike you were right. Fortunately there wasn’t any bios password…i had misunderstood it. As you suggested i bought a new Windows 8 key…something cheap from eBay and downloaded an iso and installed it. Its a squeaky clean new laptio now. Thanks mate. Appreciate it. Thank to Paolo too…
Well this in fantastic. After the cmd try mmc.exe and add the snapin active directory and users. Gess what .????
This is brutal.
