Method 1: Allow RDP in Windows Firewall

In most cases, the disconnected issue of Remote Desktop can be put down to Windows Firewall, which blocks some incoming and outgoing connections by default. Therefore, let’s check if the firewall enables remote connection first:

Method 2: Verify RDP is Enabled

Enabling Remote Desktop on the computer is another must to do for remote connections. Confirm whether RDP is allowed or not as follows:

Step 2: Click on Remote settings in the left panel of System window, and a dialog box named System Properties pops up. Check Allow Remote Assistance connections to this computer and Allow remote connections to this computer and then click on OK.

Method 3: Reset Credentials of RDP

When you connect to a remote computer with Remote Desktop Connection client, the credentials for that computer will be stored by Windows if you checked Remember me box. And next time you apply the saved credentials to log on the remote computer, which may cause an error for the two computers have different credentials. For this case, you need to reset credentials of RDP.

Step 1: Type Remote Desktop Connection in Start Search bar, and pick the best match result as the screenshot below shown.

Step 2: The Remote Desktop Connection client dialog box is open, and the credentials saved before is shown. Click edit or delete below the drop-down list to reset the credentials. Then retry the remote connection to see if the error is fixed or not.

Method 4: Make Changes to Registry

Steps: Press Windows key + R to open Run app -> Type regedit in the Run app and tap Enter -> Navigate to the following path in registry editor: HKEY_CURRENT_USER/SoftwareMicrosoft/Terminal Server Client -> Right click on the right side of the pane and click on New -> select DWORD(32-bit Value) -> Name it RDGClientTransport -> Double-click the new key and set its value data as 1 -> Click OK.

Port 3389 is set as a default port for Windows Remote Desktop. Sometimes it is occupied by other application, causing the problem remote desktop cannot connect to the remote computer. Thus, we can change the default port of Remote Desktop to fix the problem, which also can improve server security.
