The Error code 0x104 appears when trying to remotely connect to another PC using the Remote Desktop feature.
It usually arises due to misconfigured network or firewall settings but can also be a result of incorrect credentials.
To fix the issue, change the name of the exchange server, disable the active VPN, and run the critical services, amongst other solutions.

RDP or Remote Desktop Protocol, as the name suggests, allows users to access another computer remotely, i.e., without being physically present. But the connection is not as stable as many would imagine, with Error code 0x104 frequently encountered by some.

This poses a major problem, given that the feature to remotely gain access to the PC has gained prominence over the years. Though there are several third-party apps to establish remote access, let’s first try to fix the Error code 0x104 with Microsoft remote desktop.

What is error code 0x4 in Microsoft Remote Desktop?

As per the error message, Error code 0x104 arises when Windows can’t find the remote PC, and subsequently, the connection cannot be established. Here are a few reasons you might be getting the error:

The Remote Desktop feature is disabled: For the feature to work, you must first enable Remote Access in Windows. And if it’s disabled, the error will show up.
Misconfigured firewall settings: You may come across Error code 0x104 if the firewall settings are misconfigured.
Network Discovery is turned off: Enabling Network Discovery is critical for your PC to identify others on the network and remotely connect to them.
Incorrect DNS server: An incorrect DNS is just as likely to trigger the error, but this can easily be fixed.

How can I fix error code 0x104?

Before we head to the slightly complex solutions, here are a few quick ones to try:

Turn on the Airplane Mode on the device you are using to connect to the remote desktop, disable it in 15-30 seconds, and then try establishing a connection.
Change the name of the exchange server to something simple in case the current one is lengthy or intricate.
When remotely connecting to the desktop via a mobile phone, try switching the network type. Say, if you are one 4G, try 3G, 4G LTE, or 5G if available.
Try establishing a connection using the PC’s IP address (check in the desktop settings) instead of the PC name, and verify if Error code 0x104 is fixed.
Make sure Port Forwarding is enabled on your router, and contact the ISP (Internet Service Provider) to help configure a port forwarding rule for mapping an external port using TCP 3389.
If you are using a VPN while trying to remotely access the PC, disable it.

If these don’t work, move to the ones listed next.

1. Make sure Remote Desktop is enabled

Press Windows + I to open Settings, and in the System tab, click on Remote Desktop on the right.
Now, enable the toggle for Remote Desktop.

Causes Of Microsoft Remote Desktop 0x104

DNS Settings

This is the case especially if you’re using custom DNS servers, or you’ve altered DNS settings in a way they’re not favoring Windows Remote Desktop. Removing custom DNS or any settings that are causing the problem will help you establish the connection successfully.

Port blocked By Firewall

The Remote Desktop is utilizing port 3389 when using the RDP connection and if this port is blocked by a Firewall or any Antivirus software, you cannot connect to the systems you’re trying to.

Network Discovery is switched OFF

Remote Desktop Protocol is a built-in Windows utility that you can use to access computers over the same or different networks without having physical access. This is useful as you are allowed to control the target system using a few clicks from your office or home. There are tons of third-party RDP utilities out there. The built-in RDP might not “really” be the best off of them; most users still prefer to use it. Of course, there are some issues with it as well, like any other software. The one we are going to discuss in this article is the error code 0x104.

Remote Desktop Error 0x104

This error message pops up when you are trying to connect to the target system on the same or a different network. The error message states “We couldn’t connect to the remote PC because the PC can’t be found. Please provide the fully-qualified name or the IP address of the remote PC, and then try again”. This can be due to your DNS settings, network discovery options or occasionally, the Windows defender firewall privacy settings.

What causes the Remote Desktop Error Code 0x104?

The cause of the error message can vary depending on different scenarios. Nonetheless, it is often due to the following reasons —

Network Discovery Turned Off: If the network discovery option is turned off in your Sharing options then that can be the reason for the appearance of the error message.
Port Blocked by Windows Firewall: Remote Desktop uses the 3389 port by default for RDP connections. In case it is being blocked by Windows Firewall, you will not be able to establish a connection.
DNS Settings: If you are using any custom DNS servers, the issue might be rising because of that. In such a case, you will have to remove them and then try establishing a connection.

With that said, you can follow the solutions given down below to fix your issue. Please make sure you follow them in the same order as provided.

Solution 1: Turn on Network Discovery

Network Discovery is an option using which you can determine whether your system can see/scan other systems on the network or not. You have to make sure this option is turned on to establish an RDP connection. Here’s how to do it:

Open up the Control Panel.
Go to Network and Internet > Network and Sharing Center.
Then, on the left-hand side, click on ‘Change advanced sharing settings’.
Expand the network profile that you are currently using and select ‘Turn on network discovery’.
Turning on Network Discovery
Click Save Changes.

Solution 2: Allow Port 3389 Port through Firewall

Like we mentioned earlier, the 3389 port is the default port that is used by Remote Desktop for connections. If in case, it is blocked by the Windows Firewall, you won’t be able to make a connection. Also, you must choose a strong password and username for the connection to secure yourself from malicious attackers. Here’s how to allow the port through the firewall:

Press the Windows Key to open up the Start Menu.
Type in Remote Settings and hit Enter. This will open up the System window.
On the left-hand side, click on Remote settings.
Under Remote Desktop in the Remote tab, make sure Allow remote connections to this computer is selected.
Allowing Remote Connections
Now, open up the Control Panel.
Go to System and Security > Windows Defender Firewall.
On the left-hand side, click on ‘Advanced settings’.
Now, select Inbound Rules and then search for Remote Assistance (RA Server TCP-In).
Make sure it is enabled.
Now look for Remote Desktop – User Mode (TCP-In and UDP-In). Make sure they are enabled and 3389 is the port. You can check the port by expanding the window so that the Local Port column is visible.
Remote Desktop Firewall Rules
Try establishing a connection again.

Solution 3: Clear Custom DNS Servers

If you are using a custom DNS server(s) on your system, you will have to clear it before establishing a remote connection. This applies to both the host and target system. Here’s how to do it:

Right-click on the Network icon in the taskbar and select Open Network and Internet settings.
Click on ‘Change adapter options’.
Network Settings
Right-click on your adapter and select Properties.
Highlight Internet Protocol Version 4 and select Properties.
Make sure ‘Obtain DNS server address automatically’ is selected.
Click OK.
Try connecting again.

Код ошибки удаленного рабочего стола 0x104 в Windows 10 возникает, когда вы пытаетесь предоставить доступ к системе, которая доступна в той же или в другой сети. Но когда это не удается, вы можете увидеть сообщение об ошибке, в котором говорится:

Не удалось подключиться к удаленному ПК, потому что компьютер не может быть найден. Укажите полное имя или IP-адрес удаленного ПК, а затем повторите попытку. Код ошибки 0x104

Этот вопрос может быть очень сложным. У некоторых пользователей, которые пытаются подключиться к своим удаленным серверам, также возникают проблемы с подключением к Интернету. Однако вот несколько простых методов, которые могут помочь вам избавиться от этого беспорядка.

Чтобы исправить код ошибки удаленного рабочего стола 0x104 на вашем компьютере, выполните следующие действия:

Включите обнаружение сети
Очистить настраиваемые DNS-серверы
Разрешите порт 3389 в брандмауэре Windows.

Давайте посмотрим на них подробнее.

1]Включите обнаружение сети

Обнаружение сети — это функция, которая позволяет вашему компьютеру определять дополнительные устройства, доступные в той же сети. Это упрощает обмен файлами и принтерами между нужными вам сетями. Чтобы установить соединение RDP, вы должны убедиться, что эта опция включена или нет. Итак, давайте посмотрим, как включить Network Discovery:

Откройте панель управления и в поле поиска введите Сеть и Интернет. Нажмите Enter и на следующей странице выберите Центр коммуникаций и передачи данных вариант.

На левой боковой панели выберите Изменить расширенные настройки общего доступа связь.

Разверните сетевой профиль, который в настоящее время используется для вашего сетевого подключения. После этого выберите переключатель рядом с Включите обнаружение сети.

Наконец, нажмите Сохранить изменения кнопка.

2]Разрешить порт 3389 в брандмауэре Windows

TCP-порт 3389 — это порт по умолчанию, который используется для протокола удаленного рабочего стола Windows. Этот порт также используется в брандмауэре Windows для подключения других устройств, доступных либо в той же сети, либо в разных сетях. Однако, если брандмауэр Windows заблокирует это, вы не сможете предоставить им доступ.

Чтобы установить соединение, вам необходимо разрешить порт 3389 в брандмауэре Windows. Вот как это сделать:

Откройте окно Панели управления, выберите Система элемент.

На левой панели следующего экрана выберите Удаленные настройки связь. Это откроет Свойства системы мастер, где убедитесь, что вы на Удаленный таб.

Под Удаленный рабочий стол раздел, установите флажок рядом с Разрешить удаленные подключения к этому компьютеру.

Нажать на Подать заявление > Ok кнопку, чтобы сохранить изменения.

Теперь снова откройте окно панели управления и выберите Брандмауэр Защитника Windows элемент.

На левой панели выберите Расширенные настройки связь. На следующем экране выберите Входящие правила.

Перейдите на правую панель и найдите Удаленный помощник (входящий TCP-сервер RA) под Имя столбец.

Как только вы его найдете, убедитесь, что он включено.

Теперь узнай Удаленный рабочий стол — режим пользователя (TCP-входящий) и Удаленный рабочий стол — режим пользователя (UDP-вход).

Убедитесь, что оба параметра включены и 3389 это локальный порт. Чтобы сделать локальный порт видимым, перетащите горизонтальную полосу прокрутки к правому краю.

После этого попробуйте снова установить соединение и проверьте, устранен ли код ошибки 0x104.

3]Очистите настраиваемые DNS-серверы, чтобы исправить код ошибки 0x104

Если включение сетевого обнаружения не решает проблему, вы можете попытаться решить ее, очистив настраиваемый DNS-сервер перед настройкой удаленного подключения. Он легко применим как к основной, так и к целевой системам. Попробуем очистить кастомные DNS-серверы. Сделать это —

Откройте меню WinX, используя Windows + X Сочетание клавиш.

В списке меню выберите Настройки > Сеть и Интернет.

Переместитесь в правую панель и нажмите Изменить параметры адаптера.

На странице «Сетевые подключения» найдите свой адаптер.

Как только вы найдете, щелкните его правой кнопкой мыши и выберите Характеристики вариант.

В соответствующем мастере свойств убедитесь, что вы находитесь на Сети таб.

После этого установите флажок рядом с Интернет-протокол версии 4 а затем выберите Характеристики кнопка.

Также убедитесь, что Получить адрес DNS-сервера автоматически выбрано.

Нажмите кнопку ОК, чтобы сохранить изменения, а затем попробуйте подключить его снова.
