I forgot the administrator password on my windows server 2012

Hello,

I need help. I setup my Windows Server 2012, two months ago asked me to change the password and I did.   Yesterday a tried to sign in and says the password is wrong.

How can I reset this password?

Thank you very much for any help.

Is it in a domain?
Or is that the DC?

I've had great luck over the years with an open source Linux based "live boot CD" from http://pogostick.net/~pnh/ntpasswd/

Create a USB stick or bootable CD from that site, and then use it to clear your password.  I have not had good luck SETTING a password, but clearing it has always worked for me.

And..  as PJAM is asking..  my recommendation is if it's a LOCAL password, NOT a domain password.  If you're looking to recover a DOMAIN ADMIN password, then the local boot disk wont work..  If it's a workgroup machine, or even a local password on a domain joined machine, the boot disk is the way to go.

Use your Windows DVD to boot the system, rename utilman.exe in c:\windows (or c:\windows\system, I forget off hand which folder) to utilman.exe.backup and then COPY cmd.exe to utilman.exe.  Reboot into windows and use the accessibility/help option which should now open a command prompt.  Then type NET USER <username> <newpassword>.

Reboot to the Windows CD, rename things back, and reboot to Windows and the new password should take effect - a 5 minute video detailing this is found here:

Thank you for answer.
My system is X3500 M4 IBM
I put the Windows DVD. my system says X:\Sources>
I changed to X: but when I put dir/p I cannot find utilman.exe just utildll.dll

Any idea?  Thank you

Not sources.  Windows must load the drivers for the storage controller - you may have to provide them if it didn't.

Check other drive letters - Your server's actual C: drive may not be the C: drive when booted to the DVD... it might be D: or E: or F:.  You need to find the SERVER INSTALLATION'S drive - watch the video.

It's funny you use utilman.exe, personally I've always used the sticky keys executable (what other use is there for sticky keys, eh?) ;)

That's awesome..  I haven't used that technique since NT 4.0  we used to use a parallel install to set the screen saver to cmd.exe and go from there..  I can't believe that type of hack is still a working hack.. good call on that - I'm definitely going to play with that just to see it work again..
