Reset and recover password using CMD in Windows Server 2019

The use of passwords is one of the most used security measures for many years and thanks to which, as long as this password is complex and secure, it will prevent unauthorized access to the system and therefore avoid all the problems covered by the Access not due which affects files , roles and other elements hosted on the system..

As system administrators it is normal that at some point we forget the password of the Administrator user , this is the user that is installed by default during installation and is local, which has privileges to carry out processes in the system and its services, The reason we can forget this password is because sometimes we have to keep in mind passwords of many things (applications, mail, more users, etc.), so we forget this one that is vital for security and accessibility to the server. If you use any other version of Windows Server, here is also how to do it:

Reset and recover password using CMD in Windows Server 2019

Step 1

The first step to take is to have the bootable DVD or USB with the ISO image of Windows Server 2019, insert it in the respective drive and proceed to turn on or restart the operating system. During this process we must press any key to access the following window: image
Step 2

There we leave the established values ​​and click on “Next” where we will see the following: image
Step 3

In this section we click on the “Repair the equipment” line in order to access the advanced mode where we will first see the following window: image
Step 4

There we select the "Troubleshoot" option and we will be redirected to the following window: image
Step 5

There we click on the "Command Prompt" option and in the deployed console we execute each of the following commands:
 d: cd Windows cd System32 move utilman.exe utilman.exe.bak copy cmd.exe utilman.exe net user administrator / active: yes 
image
Step 6

There we have done the following:
Access to Windows Server 2019 ISO image location
 d 
Access the System32 directory
 cd Windows \ System32 
Create backup copy of the Utilman executable
 move utilman.exe utilman.exe.bak 
Copy cmd to replace the Utilman function that covers the narrator, the magnifying glass, etc.
 copy cmd.exe utilman.exe 
Activate the Administrator user
 net user administrator / active: yes 
Step 7

After this process, we restart the server by running the following:
 shutdown -r -t 0 
Step 8

Now, when we get to the login screen we have two options:
  • Use the following key combination:

+ U

  • Click on the icon located in the lower right
Step 9

This will cause the command prompt console to be displayed and there we will assign a new password by executing the following:
 net user administrator “password” 
image
Step 10

After this we execute the “exit” command to exit the command prompt and we can enter the new password for the Administrator user: image
Step 11

Now we will have normal access to Windows Server 2019 to be able to perform all the tasks: image
Note
If at any time we wish to restore the original values ​​we must repeat this process, but this time execute the following:
 utilman.exe ren utilman.exe.bak utilman.exe 

It is worth remembering the importance of assigning a secure password and, if possible, creating another user who has administrative permissions to also access another account and be able to change the password from the user interface. As we can see, it is a simple and effective process for changing the password of the Administrator user in case we have forgotten it..
