You can use this article to reset it. This article for Window7 and window2008. You can reset the same way of windows7 password reset. You should have windows DVD to reset using this article.

If not clear please post back.

Hi,

If you forget or lost your local administrator to your server, don’t panic. I'll highlight the process to reset your password.

1. Boot from the Microsoft Windows Server 2012 DVD (Alternatively, you can boot with WinPE ISO)
2. From the Windows Setup menu, click “Next”.
3. Select “Repair your computer
4. Under Choose and option, click on “Troubleshoot”.
5. Under Advanced options, click “Command Prompt”.
6. At the command prompt, run the following commands:
C:
cd windows\system32
ren Utilman.exe Utilman.exe.old
copy cmd.exe Utilman.exe

7. Close the command prompt and then click “Continue”.
Allow server to boot normally into Windows
8. At the logon screen, click the Ease of Access button in lower left of screen. This should now bring up a command window under the Local System User context (Windows Key +U)
9. At the prompt you can now change the password, by typing the following command:
net user administrator Newpassword
This will set the password for the Administrator user to be Newpassword
10. Closing the command prompt, you should now be able to log back onto the server using the password you have provided in the last step.

@MAS,

Links die sometimes.  Content in the question does not. Emmanuel Adebayo posted appropriately, copying and pasting the instructions as well as a source link.

It will not work if it is disabled for you.
Follow this

1. Boot with the official windows DVD.
2. From the Windows Setup menu, click “Next”.
3. Click on "Repair your computer".
5. From the  "System Recovery Options" window, select your OS i.e. Microsoft windows server 2008 / Windows7 and click "Next".
6. Click on "Command prompt".
7. You will get a command prompt with a path of "X:\Sources>".  type "C:" and enter.
8. Now navigate to "c:\windows\system32"  by typing "cd c:\windows\system32" and enter.
9. Type the command "move  sethc.exe sethc.exe.bak" and enter.
10.Then type the command "copy  cmd.exe  sethc.exe" and enter.
11. Now exit command prompt and restart server.
12. When you see the prompt "press CTRL+ALT+DEL to logon" press the shift key 5 times or more, you will get a command prompt window.
13. Syntax is "net user <username> <new password>".
You type the command "net user administrator P@ssw0rd" in the command prompt windows to change the password to "P@ssw0rd"  and you will get confirmation saying that "The command completed successfully" if the password is changed.
14. You can login to the server with the password "P@ssw0rd"
15. To restore the functions of sethc.exe repeat steps 1 to 8 then continue from step 16.
16. From the command prompt type  "ren sethc.exe cmdtemp.exe".
note:One of the command may show you error which you can ignore. But make sure one command ran without issue. Later you can delete the files named "cmdtemp.exe", "cmdtemp1.exe" from "c:\windows\system32" after logged in to the server.
17. Type "ren sethc.exe.bak sethc.exe".

Restart and you can continue working.
