В этой статье мы рассмотрим сценарий сброса пароля администратора домена Active Direcotory. Эта возможность может понадобиться в случаях утраты прав доменного администратора вследствие, например, «забывчивости» или намеренного саботажа увольняющегося админа, атаки злоумышленников или других форс мажорных обстоятельствах. Для успешного сброса пароля администратора домена необходимо иметь физический или удаленный (ILO, iDRAC или консоль vSphere, в случае использования виртуального DC) доступ к консоли сервера. В данном примере мы будем сбрасывать пароль администратора на контроллере домене с ОС Windows Server 2012. В том случае, если в сети несколько контроллеров домена, рекомендуется выполнять процедуру на сервере PDC (primary domain controller) с ролью FSMO (flexible single-master operations).

Для сброса пароля домен-админа необходимо попасть в режим восстановления службы каталогов – DSRM (Directory Services Restore Mode) с паролем администратора DSRM (он задается при повышении уровня сервера до контроллера домена). По сути это учетная запись локального администратора, хранящаяся в локальной базе SAM на контроллере домена.

В том случае, если пароль DSRM не известен, его можно сбросить таким способом, или, если администратор обезопасил сервер от использования подобных трюков, с помощью специализированных загрузочных дисков (типа Hiren’s BootCD, PCUnlocker и им подобных).

Итак, загружаем контроллер домена в DSRM режиме (сервер загружается с отключенными службами AD), выбрав соответствующую опцию в меню расширенных параметров загрузки.

На экране входа в систему вводим имя локального пользователя (administrator) и его пароль (пароль DSRM режима).

В данном примере имя контроллера домена – DC01.

Проверим, под каким пользователем выполнен вход в системе, для этого выполним команду:

   USER INFORMATION
   —————-
   User Name          SID
   ================== ============================================
   dc01administrator S-1-5-21-3244332244-383844547-2464936909-500

Как вы видите, мы работаем под локальным админом.

Следующий шаг – смена пароля учетной записи администратора Active Directory (по умолчанию это учетная тоже называется Administrator). Сбросить пароль администратора домена можно, например, создав отдельную службу, которая при старте контроллера домена из под системной учетной записи сбросила бы в Active Directory пароль учетной записи Administrator. Создадим такую службу:

sc create ResetADPass binPath= "%ComSpec% /k net user administrator P@ssw0rd" start= auto

Примечание. Обратите внимание, при задании пути в переменной binPath, между знаком ‘=’ и ее значением необходим пробел. Кроме того, новый пароль должен обязательно отвечать доменным требованиям длины и сложности пароля.

Указанная команда создаст службу с именем ResetADPass, которая при загрузке системы с правами LocalSystem выполнит команду net user и изменит пароль администратора AD на P@ssw0rd.

С помощью следующей команды мы можем удостовериться, что служба была создана корректно:

   [SC] QueryServiceConfig SUCCESS
   SERVICE_NAME: ResetADPass
   TYPE               : 10  WIN32_OWN_PROCESS
   START_TYPE         : 2   AUTO_START
   ERROR_CONTROL      : 1   NORMAL
   BINARY_PATH_NAME   : C:Windowssystem32cmd.exe /k net user administrator P@ssw0rd
   LOAD_ORDER_GROUP   :
   TAG                : 0
   DISPLAY_NAME       : ResetADPass
   DEPENDENCIES       :
   SERVICE_START_NAME : LocalSystem

Перезагрузим сервер в нормальном режиме:

Во время загрузки созданная нами служба изменит пароль учетной записи амина домена на заданный. Авторизуемся на контроллере домена под этой учетной записью и паролем.

   USER INFORMATION
   —————
   User Name             SID
   ===================== ============================================
   corpadministrator S-1-5-21-1737425439-783543262-1234318981-500

Осталось удалить созданную нами службу (FAQ. Как удалить службу в Windows):

[SC] DeleteService SUCCESS

Итак, в этой статье мы разобрались, как можно сбросить пароль администратора домена AD, и еще раз намекнули о том, насколько в концепции информационной безопасности важен момент обеспечения физической безопасности Вашей IT инфраструктуры.

Hi,

If you have created a password reset disk for your account, you can reset your forgotten administrator password easily. On the login screen, once you login your user account failed, you will see there is a link to reset password under the password box. Otherwise,
you need the installation media or other admin account to reset the password.

Задача: Разобрать шаги по сбросу пароля на Windows Server 2012 R2

Итак, у меня есть установленный образ Windows Server 2012 R2 Std под Virtualbox моей основной системы ноутбука Lenovo E555 Ubuntu Trusty Desktop (рабочее окружение Gnome Classic).

Запускаю пакет управления виртуальными машинами:

Приложения — Системные утилиты — Oracle VM Virtualbox, нахожу контейнер с именем WS2012R2_#1, запускаю его и открываю свойства данной виртуальной машины чтобы смонтировать с развернутой системой установочный диск с которого сейчас нужно будет произвести запуск:

Устройства — Оптические диски — Выбрать образ диска и указываю путь до местонахождения в системе установочного образа, в моем случае: Server2012R2_EN_DV9.ISO

Затем отправляю виртуальную машину в перезагрузку

VM: WS2012R2_#1 — Машина — Перезапустить (или сочетание клавиш: Ctrl + R если окно консоли виртуальной машины открыто), в момент когда на экране появится надпись «Press any key to book from CD or DVD» нужно нажать клавишу Enter, после чего соглашаемся (нажимаем кнопку Next) с выставленными настройками установщика, такими как:

Language to install: English (United States)
Time and currency format: English (United States)
Keyboard or input method: US

На следующем шаге нужно не нажимать «Install Now», а нажать «Repair your computer», см. скриншот ниже для наглядного понимания:

После входа в расширенное меню следует перейти нажав на иконку с изображением отвертки и гаечного ключа (Troubleshoot), а потом на иконку с изображением консоли командной строки (Command Prompt) и передо мной предстает запущенная консоль, как можно заменить с правами Администратора ожидающая ввода команд:

Здесь нужно ввести следующие команды аналогичные тем которые вводились в заметке по сбросу пароля на системную учетную запись в Windows Server 2008 R2, но можно и не сбрасывать пароль, а создать логин и пароль и дать административные привилегии:

X:Sources>copy d:WindowsSystem32Utilman.exe d:WindowsSystem32Utilman.exe.backup

X:Sources>copy d:WindowsSystem32cmd.exe d:WindowsSystem32Utilman.exe

Overwrite d:WindowsSystem32Utilman.exe? (Yes/No/All): y

Затем отключаю смонтированный инсталляционный образ Windows от контейнера с виртуальной системой:

Устройства — Оптические диски — Изъять диск из привода

Выключаю VM, закрыв открытое окно консоли командной строки и нажав на иконку «Turn off your PC»

Включаю VM, когда экран встанет на этапе нажатия сочетания клавиш: Ctrl + Alt + Del нужно нажать вот сюда (см. скриншот ниже), если не проделывалась процедура подмены исполняемого файла Utilman.exe, то ранее здесь бы запустилась утилита «Центра специальных возможностей», но т. к. я ее подменил, то запуститься консоль командной строки с правами СИСТЕМЫ, а это много больше чем административные права:

Когда такая консоль, системная консоль запущена в этот момент с системой можно делать все что угодно, создавать административного пользователя:

C:Windowssystem32net user ekzorchik 712mbddr@ /add

C:Windowssystem32net localgroup Administrators ekzorchik /add

Сбросил пароль на дефолтную административную учетную запись с логином Administrator:

C:Windowssystem32net user Administrator 712mbddr@

По такому же принципу, но с использованием консольных команд можно делать с системой все что необходимо.

После того, как нужно еще раз загрузиться с установочного диск и произвести возврат utilman.exe на свое законное место, т. к. если попытаться проделать эту процедуру авторизовавшись в системе под административной учетной записью сделать этого не получиться. В доступе на такое посягательство исполняемых файлов администратору системы будет отказано от системы.

C:Windowssystem32copy Utilman.exe.backup Utilman.exe

Overwrite Utilman.exe? (Yes/No/All): y

Access is denied.

К чему я писал данную заметку, просто у меня несколько дней назад была история. На домен контроллере поехало время, остановилась репликация, не работала авторизация ни под какой учетной записью на домен контроллере под управлением Windows Server 2012 R2 Standard, а вот с помощью шагов выше я попал в систему через восстановление контроллера домена и восстановил контроль на инфраструктурой. На этом у меня все, с уважением автор блога Олло Александр aka ekzorchik.

You forgot the domain admin password? This article explains how you can reset the administrator password in a Windows Server 2008 (R2) and Windows Server 2012 (R2) domain.

First of all, you should never work with the “Administrator” account. Each admin should have his own account, for two reasons. First, it makes troubleshooting easier if an admin messes up. Second, if one admin forgets his password, another admin can reset it through Active Directory Users and Computers (ADUC). Whenever you reset a password, however, note that the corresponding account will no longer be able to access passwords stored in Internet Explorer or files that have been encrypted with EFS.

If you forgot the domain admin password, and no other administrator exists in this Windows domain, you can use the procedure below to reset the password. Note that the screenshots are for Windows Server 2012 R2 with Update. However, this guide also works for Windows Server 2012 and Windows Server 2008 R2.

With this password reset method, you have to boot from a second Windows installation. You then have to replace utilman.exe (the Utility Manager with ease-of-use functions such as the Narrator and Magnifier) on a domain controller with the command prompt (cmd.exe). Next, you’ll boot up the machine where you forgot the password, click the Utility Manager icon on the logon screen to launch a command prompt, and then reset the password. Here is the step-by-step guide:

Subscribe to 4sysops newsletter!

Boot from a Windows Server 2012 R2 DVD (or ISO file in a virtual environment) and click Next when Windows Setup loads.
Press SHIFT + F10 to open a command prompt.
At the command prompt, enter:
```
move d:windowssystem32utilman.exe d:windowssystem32utilman.exe.bak
```
Note: On Windows Server 2008 R2, you will most likely have to replace the drive letter d: with c:. If you are unsure about the drive letter, search for the drive that contains the Windows folder. The driver letter for the instance of Windows PE that started Windows Setup is x:. (Update: As mentioned by Chidi, you can run the diskpart command and then on the displart prompt, you can enter the list vol command to get an overview of the available drives. The system drive should be labeled accordingly.)
Replace utilman.exe with cmd.exe:
```
copy d:windowssystem32cmd.exe d:windowssystem32utilman.exe
```
Remove the boot media from the server and tell Windows PE to reboot:
```
wpeutil reboot
```
Once your domain controller is running again, click the Utility Manager icon.
At the command prompt that (I hope) opened, reset the domain admin password with this command:
```
net user administrator *
```
You can now close the command prompt and log on with the new password. However, mainly for security reasons, I highly recommend restoring the original utilman.exe. For this, you have to again boot Windows Server setup, follow steps 1-2, and then enter:
```
move /y d:windowssystem32utilman.exe.bak d:windowssystem32utilman.exe
```
(Replace the drive letter if Windows isn’t installed on the d:)
After you removed the boot media, you can reboot the server again with
```
wpeutil reboot
```

Obviously, this procedure can be used by anyone who has physical access to your servers. In my next post I will give you a few tips how you can prevent the Utilman.exe password reset trick.

It comes the time that for some reason you may forget Windows Server 2012 administrator password and locked yourself out of computer. Before going further, if your Server 2012 (R2) machine is a DC in the domain, the first thing you should do is check if there is any other user that has admin privileges. If so, you can use that user to reset Windows server 2012 admin password.

If you have no other administrator account, there is no need to worry, a lot of Windows Server 2012 password reset or recovery tools out there have made it easy for you to recover or reset password in Windows Server 2012 R2 and get you back in to system again.
