Resetting the admin password on a DC 

Apr 02, 2014 03:57 PM

Hello all,

Recently I forgot the domain admin password for my lab, and was looking at a possible rebuild of the Domain Controller as a worst-case-scenario.

Luckily, I found the folloiwng blog today which had me up-and-running again within minutes:-

You basically do the following:

1.  Boot to installation media.

2.  Go to the repair option and choose the command window function.

3.  Change to the DC's system32 directory and perform following two actions:

4.  copy Utilman.exe Utilman.exe.bak

5.  move Cmd.exe Utilman.exe

6.  Reboot.

7.  Windowskey+U or press the accessibility icon.

8.  A Utilamn command window will open.

9.  net user administrator password

10.  Reboot and confirm login now works.

11.  Go through steps 1, 2 & 3.

12.  ren Utilman.exe Cmd.exe

13.  ren Utilman.exe.bak Utilman.exe

14.  Reboot and BAU baby.  :-)
