Fix: The Specified Domain Either Does Not Exist or Not Contact
When you try to connect to join a domain on any Windows operating system or after entering a username and correct password, you may receive an error with the message “the specified domain either does not exist or could not be contacted”. Well, this article from MiniTool Partition Wizard shows you several ways to fix it.
This “the specified domain does not exist or could not be contacted” error is usually due to invalid DNS settings on the workstation, as Active Directory requires domain DNS (not the router’s address) to function properly. The error can also occur because IPv6 does not work.
Well, how to fix the “the specified domain either does not exist or could not be contacted” error? Please keep reading.
Before trying the solutions below, if you have IPv6 configured, you can disable the protocol and then release TCP/IP, and flush DNS, which may resolve DNS issues on Windows 11/10.
Way 1: Change the DNS Server Address
To resolve the ” the specified domain either does not exist or could not be contacted ” error, you should set the preferred DNS IP to point to the IP address of the primary domain controller on each client workstation that is joining the domain. To do so, here is the guide.
Step 1: Press the Win + R key to open the Run box. Then type ncpa.cpl in it and press Enter to open the Network Connections control panel.
Step 2: Right-click the local area connection and click Properties.
Step 3: Double-click Intel Protocol TCP/IPv4.
Step 4: See the exact IP for your computer. Then change the Preferred DNS server address to match the Primary Domain Controller’s IP address.
Step 5: Then click OK to close all windows.
Way 2: Specify the WINS Server’s IP Address on the Client
If your Active Directory domain controller is also acting as a WINS server, you can set the WINS IP address to point to the WINS server (the IP address of the primary domain controller) on the client computer you want to join the domain. The steps are as follows:
Step 1: Open the Network Connections control panel. Then right-click the local area connection and click Properties.
Step 2: Double-click Intel Protocol TCP/IPv4. Then navigate to Advanced > WINS > Add.
Step 3: In the WINS server filed, type in the IP address and click Add. Then click OK to apply changes.
After that, you should now be able to join the workstation to the domain without the “the specified domain either does not exist or could not be contacted” problem recurring.
Way 3: Change a Certain Registry Key
Modifying the value of the SysVolReady registry entry on the domain controller may resolve this issue. Since this is a registry operation, it is recommended that you back up the registry or create a system restore point as a necessary precaution. Once done, you can do the following:
Step 1: Press the Win + R key to open the Run box. Then type regedit in it and press Enter.
Step 2: Navigate to the following path:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesNetlogonParameters
Step 3: On the right panel of the window, right-click the SysVolReaady entry and select the Modify option.
Step 4: Under the Value data section, change the value to 1. Then click OK to save the change.
Once done, restart your computer and see if the problem is gone.
Bonus: How to Fix the Domain Specified Is Not Available
When working remotely through an Active Directory Domain Services (AD DS) environment, you try to log on with a smart card, but the message ‘The system cannot log you on. The domain specified is not available. Please try again later. ‘
Typically, this happens when you disconnect your PC from the AD DS environment and log back in. So, what should you do now if you get an error message? There are two methods to fix it.
Method 1: Verify Your Credentials
The problem might actually be with the credential authentication system. You can use Certificate Manager to access credentials stored in client certificates. Once there, go to the Details tab and check that your username is under the User Principal Name list.
Method 2: Use Microsoft’s Hotfix
Patches can be an alternative system to fix domain-specific issues. Microsoft has a fix specifically for this situation that you can download and apply to resolve the issue.

Every Windows computer can be protected by a password, a pin, or a combination of both – there are also additional security measures that users can employ if required. The login lockscreen is extremely important when it comes to privacy and computer safety, especially when it comes to public or corporate computers. Likewise, home users can also use the feature to prevent curious household members from accessing their accounts.
Unfortunately, some users might forget their passwords, or errors when logging in might occur. While usually, the incorrect password would simply result in an error message that would say so, some users have encountered something completely different – “The specified domain either does not exist or could not be contacted” error.
While the error can also be encountered when trying to join a domain network, it can usually be resolved by changing the DNS settings. However, this instance is completely different, as it seems like Windows is attempting to contact a domain upon when a login attempt to the system is made.
In most cases, the “The specified domain either does not exist or could not be contacted” error occurs when the computer was connected to a domain previously. When users try to reset the operating system for one reason or another – that’s when the issue shows up, preventing users from logging in at all.
It goes without saying that such an error might cause significant issues, as users are essentially locked out of their PCs and are not able to connect. In order to fix the “The specified domain either does not exist or could not be contacted” error, you will have to access the Windows Recovery environment and perform actions there.

Причиной ошибки “The specified domain either does not exist or could not be contacted/ Указанный домен не существует, или к нему невозможно подключиться” в Windows чаще всего являются некорректные сетевые настройки (IP адрес, DNS сервера, шлюз по умолчанию) на клиентском компьютере, в результате чего компьютер не может подключиться к контроллеру домена Active Directory и выполнить аутентификацию.
Ошибка: “Указанный домен не существует” при добавлении компьютера в Active Directory
The following error occurred attempting to join the domain WINITPRO. The specified domain either does not exist or could not be contacted.
Это означает, что с этого компьютера не доступен указанный домен AD. Причина может быть в некорректном IP адресе компьютера или неверных настройках DNS, в результате чего Windows не может отрезвить IP адрес контроллера домена по его DNS имени.
- Проверить корректность работы сети на компьютере и его сетевые настройки
- Проверьте корректность работы DNS
Проверьте, что ваш компьютер получил корректные сетевые настройки IP от DHCP сервера. Выведите сетевые настройки вашего подключения с помощью команды:
Get-NetAdapter -Physical | ? | Get-NetIPConfiguration
Проверьте, что на вашем компьютере задан корректный IP адрес из вашего сегмента сети.
Попробуйте обновить IP адрес:
Проверьте доступность DNS сервера:
Test-NetConnection 192.168.13.10
Test-NetConnection 192.168.13.10 -Port 53
В этом примере DNS сервер доступен по ICMP ( PingSucceeded:true ) и на нем открыт DNS порт ( TcpTestSucceeded:True ).
Проверьте, что данный DNS сервер может разрешить имя домена в IP адрес:
Проверьте, что в вашем локальном файле hosts отсутствует ручные записи для вашего домена:
Get-Content -Path «C:\Windows\System32\drivers\etc\hosts»
Если в настройках сетевого интерфейса указан неверный IP адрес вашего DNS сервера или он не доступен, вы можете задать его вручную через панель управления сетевыми подключениями. Откройте панель ncpa.cpl -> свойства сетевого адапретера -> свойства TCP/IPv4 -> Preffered DNS server. Задайте здесь IP адрес вашего ближайшего контроллера домена AD.
Очистите DNS кэш:
ipconfig /flushdns
net stop dnscache
net start dnscache
Если этого не сработало, нужно дополнительно нажать на кнопку Advanced:
- На вкладке DNS включите опцию Use this connection’s DNS suffix in DNS registration и вручную укажите имя домена в DNS suffix for this connection;
- Затем на вкладке WINS вручную добавьте IP адрес вашего DC.
В некоторых случаях помогает отключение протокола IPv6 на сетевом интерфейсе.
Попробуйте теперь выполнить обнаружение контроллеров домена в DNS:
И возможность подключения к контроллеру домена в вашем сайте:
Попробуйте еще раз добавить компьютер в домен AD.
«Указанный домен не существует» при входе в Windows
Ошибка “Указанный домен не существует, или к нему невозможно подключиться” может появится при попытке входа в Windows под доменной учетной записью.
Эта ошибка может указывать на то:
- Недоступность контроллера домена с компьютера (неверные сетевые настройки в Windows);
- Если проблема проявляется на нескольких компьютерах, возможно это указывает на ошибки в работе контролера домена.
Если проблема возникла на одном компьютер, попробуйте войти под локальной учетной записью (укажите имя .\administrator на экране входа в Windows). Если вы не знаете пароль локального администратора, можно сбросить его. Проверьте корректность сетевых настроек компьютера, доступность DNS сервера и контроллера домена. Исправьте настройки IP вручную, если нужно.
При недоступности DC вы можете войти в Windows под любой доменной учетной запись, которая входила на него ранее. Это обеспечивается функцией Cached Credentials, позволяющей войти в Windows под сохраненными учетными данными при недоступности домена. Если кэширование отключено, при попытке входа появится ошибка:
Если проблема возникает на нескольких компьютерах, проверьте что на вашем контроллере домена (Logon сервере) запушена служба NetLogon:
Проверьте что на DC опубликованы сетевые папки SYSVOL и NETLOGON. Если они отсуствууют, измените значение параметра реестра SysvolReady с 0 на 1 в ветке HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters и перезапустите службу NetLogon.
Выполните диагностику контроллеров домена и репликации с помощью команд dcdiag и repadmin .

FIX: The Specified Domain Either Does Not Exist or Could Not Be Contacted (Solved)
This tutorial contains instructions to resolve the following problem, when you try to join a Windows based computer to an existing domain: «The Specified Domain Either Does Not Exist or Could Not Be Contacted».
The error «The Specified Domain Either Does Not Exist or Could Not Be Contacted» commonly occurs due to invalid DNS settings on the workstation’s side, because Active directory requires you to use domain DNS to work properly (and not router’s address).
How to fix: Specified Domain Does Not Exist or Could Not Be Contacted.
Let’s suppose that your Active Directory Domain Controller (and DNS Server) is a Windows Server 2016 machine and is responsible for the domain «wintips.local» and has the IP Address «192.168.1.10».
At this example, the IP and the Preferred DNS address on the Primary Domain Controller (Server 2016) must be the same, e.g.
| Primary Domain Controller (Server 2016) | |
| Computer Name: | Server2k16 |
| Domain Name: | WINTIPS.LOCAL |
| IP Address (Static): | 192.168.1.10 |
| Subnet Mask: | 255.255.255.0 |
| Default Gateway: | 192.168.1.1 |
| Preferred DNS Server: | 192.168.1.10 |
Method 1. Set the Preferred DNS Server Address to match the Domain Controller’s IP Address (on Client Workstation)
To resolve the «Specified Domain Does Not Exist or Could Not Be Contacted» error, you have to set the Preferred DNS IP to point to Primary Domain Controller’s IP address, on each client workstation that you want to join in the domain. To do that:
1. Open Network and Sharing Center.
2. Right click on Local Area Connection and click Properties.
3. Double click on Internet Protocol TCP/IPv4.
4. Change the Preferred DNS server address to match the Primary Domain Controller’s IP Address (e.g. «192.168.1.10» in this example).
6. Click OK twice and close all windows.
7. Try to join the workstation in the Domain.
Method 2. Specify the WINS Server’s IP Address on Client.
If your Active Directory Domain Controller acts also as a WINS server, then set the WINS IP address to point to WINS Server’s (Primary Domain Controller’s IP address),* on the client machine that you want to join to the Domain. To do that:
* Note: This method works even when the Primary Domain Controller does not act as a WINS Server.
1. Open Network and Sharing Center.
2. Right click on Local Area Connection and click Properties.
3. Double click on Internet Protocol TCP/IPv4.
4. Click the Advanced button.
5. At WINS tab, click Add.
6. Type at WINS Server’s IP Address filed, the IP address of the WINS server (e.g. «192.168.1.10» in this example) and click Add.
7. Press OK three (3) times to apply changes and close all windows.
8. Try to join the machine in the Domain.
