Hello! Next, we will continue to explore the world of Windows Server 2019. To be specific, let’s explain a very sensitive aspect of system security. It is about the administrator password. Of course, the use of a secure password is one of the most important security measures, as it prevents unauthorized access to the system. Additionally, when we install Windows Server 2019, the system asks us to assign the password of the administrator user. If you want more information on how to install windows server 2019, check here. This account is local and has elevated privileges to run processes on the system and its services. As you can see, this password is a sensitive part of the system security. Also, if for some reason we forget it, we will not be able to access the system. So, here I show you how to reset the administrator password in Windows Server 2019.

Prerequisite

• A DVD or USB with the Windows Server 2019 boot image.

Recovering Windows Server 2019 administrator password using CMD.

In the first place, please enter your DVD or USB and start the system as if you were going to format it. When the installation window appears, please click Next to continue.

In the next screen, you have to click on repair your computer

Here are 3 options: Continue, Troubleshoot and Turn off your PC. You have to select the 2nd option Troubleshoot.

When redirected to the following window, please select Command Prompt

Using the Command Prompt

A CMD will open immediately. Once there you must run the following commands textually:

d:
cd Windows
cd System32
move utilman.exe utilman.exe.bak
copy cmd.exe utilman.exe
net user administrator /active:yes
shutdown -r -t 0

If all goes well, the Command Prompt should look like this:

Commands have to be entered one by one. Additionally, let’s see what commands we’re running in the system. With the first 3 commands, we place ourselves in the unit where Windows Server is installed, and we navigate specifically to the System32 folder. The 4th command we introduce makes a backup of the utilman executable in case we want to restore it later. The next command allows replacing the Administrator of Utilities in the start screen by the cmd.exe. This is essential, as we will be able to modify the password using Command Prompter. The subsequent command activates the administrator user. Finally, the last command we enter restarts the server. Please note that you need to enter the commands as I leave them here so as not to make any configuration errors.

After entering the last of the commands, the server will restart. Once on the home screen press the Win+U combination. Straightaway, a CMD will open where you have to enter the next command:

net user administrator newpassword 
exit

Where newpassword is the new password that you will assign to the Windows Server administrator. The command prompt should look like this:

After setting the password, enter Exit to exit the CMD and return to the home screen. Then, enter the new password you just created. You should be able to access it without any problems.

However, if you want to restore the original values, you just have to repeat the process using the following command:

del utilman.exe ren utilman.exe.bak utilman.exe

Conclusion

As can be seen, the procedure for reset the administrator password on Windows Server is not complicated to execute. However, some users are reluctant to use CMD. But, by exactly following the instructions we give you, you will be able to recover access quickly. Before I say goodbye, I would like to invite you to join our Facebook group. All right, that’s it for now, see you next time.

Introduction

There may come a time when you need to change the admin password on your Windows Server. Your recovery options depend on whether you remember the old password or not.

If you are routinely changing a known administrator password, you can use the Windows user interface. However, when changing an unknown administrator password, you need to use the command prompt.

If you already know the current administrator password, log into your Windows Server, and simply change the password. The steps on how to do so differ depending on the version of Windows you are running.

Самый простой вариант это загрузочный диск с Windows.

Восстановление с загрузочного диска Windows

1. Загружаемся с установочного диска Windows Server (он же является и диском восстановления).
2. Сразу после выбора языка выбираем Восстановление системы (“Repair your computer”).
   Для Windows Server 2016-2019 выбираем Диагностика (“Troubleshoot”), для Server 2008 — переходим к следующему шагу.
3. Командная строка (“Command Prompt”)
4. Запускаем команды (для Windows Server 2008, 2008R2, 2016 и 2019):
   • copy c:WindowsSystem32Utilman.exe с:WindowsSystem32Utilman.exe.old
   • copy c:WindowsSystem32cmd.exe с:WindowsSystem32Utilman.exe
5. Закрываем командную строку и нажимаем Продолжить (“Continue”).
6. Переходим к смене пароля на сервере.

Восстановление с загрузочного диска Linux



Пример с использованием linux rescue cd, но подойдет и любой другой где есть командная строка и доступ к разделам Windows.

1. Список разделов, дабы понимать какой монтировать: fdisk -l
2. Монтируем раздел Windows: mount -t ntfs-3g /dev/vda1 /mnt/
3. Переименовываем /mnt/Windows/System32/Utilman.exe в Utilman.exe-bak (потом его нужно будет еще вернуть на место)
4. Переименовываем /mnt/Windows/System32/cmd.exe в Utilman.exe
5. Перезапускаем сервер: reboot
6. Запускаем Windows Server и переходим к смене пароля.

2. Выполняем команду: net user administrator 123456 , где 123456 — новый пароль

Если учетная запись Administrator заблокирована

Разблокируем её можно просто следующей командой: net user administrator /active:yes
