Start Remote Desktop Services

The 0x104 error might occur when some services required for RDP connections aren’t enabled and running. For example, users can connect to remote PCs using Remote Desktop Services. But first, verify that it is enabled and running as shown.

1 – Open Windows Search.

2 – Enter Services in the Type here to search box.

Choose Remote Desktop Developer Settings

To connect remotely, Windows may need you to have developer rights. Here’s how to activate them.

1 – Launch the Windows Settings app.

2 – Click Privacy & Security in Windows 11’s Settings app. Users of Windows 10 must select Update & Security.

3 – Choose For developers to access those settings.

4 – Check the boxes next to the Remote Desktop developer settings.

5 – To save the updated developer options, click Apply.

Unblock 3389 Port

Remote Desktop provides a default 3389 port for connections. Therefore, error 0x104 might be triggered by the Windows firewall blocking port 3389. If Windows Defender Firewall is blocking the 3389 port, follow these instructions to unblock it.

1 – Verify that Remote Desktop is enabled as described in Resolution One.

2 – Use the taskbar shortcut to launch the search tool in Windows.

3 – Enter Windows Defender Firewall with Advanced Security in the search text box. 

4 – To open the Windows Defender Firewall with the Advanced Security feature, click on it.

5 – On the left side of the firewall utility’s display, click Inbound Rules.

6 – Scroll down the list of incoming rules to discover Remote Desktop – User Mode (TCP-In) with a 3389 local port number.

7 – Right-click Remote Desktop – User Mode (TCP-In) and select the Enable Rule.

8 – Repeat the previous two steps for the Remote Desktop – User Mode (UDP-In) and Remote Assistance (RA Server TCP-In) rules by choosing their Enable options.

9 – Exit Windows Defender Firewall with Advanced Security and try to connect to your remote PC once more.

Set Automatic DNS Server

Have you set up a custom DNS server on your PC? If so, try using the automatic DNS server option instead. These are the steps for selecting the Get DNS server automatically option.

1 – Select the Settings shortcut by right-clicking the symbol for the Start button.

2 – Click network & internet to display the navigation options for that tab.

3 – To bring up more navigation options, choose Advanced network settings.

4 – Click the More network adapter options box to examine connections in the Control Panel. 

5 – Right-click your PC’s internet network adapter and select the Properties option.

6 – Choose Internet Protocol Version 4 and press the Properties button.

7 – Select the Get DNS server address automatically radio button if a custom DNS is set.

8 – Click the OK button on the IPV 4 properties window to close it.


Those probable error code 0x104 solutions will likely resolve the issue and allow you to connect to your remote computer again. But note that using the RDC app, you don’t have to employ Microsoft’s Remote Desktop Protocol. Instead, if the error 0x104 remedies in this post don’t work for you, try another third-party app, such as Team Viewer or AnyDesk.
