1. Reset domain admin password via Windows setup disk

This is a free way and is not as easy as the second way, but you are able to see and control every step you do.

Steps as follow:

First, go to the Microsoft official site and download DVD/USB Download Tool, then use the DVD/USB Download Tool to create a DVD or USB installation disk.

With the DVD/USB Download Tool, you are able to create a setup disk for Windows 7, Windows 8, Windows 10, Windows 2008, Windows 2012 or Windows 2016. I recommend you to create a Windows 10 setup disk, because the Windows 10 setup disk works fine with most of the old or new computers.

Next, boot the domain computer from the Windows setup disk.

After that, when the Windows setup program starts, choose Repair Windows and then go into the Command Prompt.

Then, on the Command Prompt, run the following commands.

reset domain controller password

Next, on the login screen, click “Easy access” icon on the lower-right corner to run the Command Prompt, then use the net user command to reset the forgotten password for the administrator account.

Note: The password must contain lowercases, uppercases, numbers and must be longer than 7 characters.

Last, close the Command Prompt, and login the computer with the new password.

Note: You must run the setup program and go to the Command Prompt again to undo the rename operation.
