How to clear "Internal error occurred" (Windows)

Client receives the following error “Internal Error occurred, trying to RDP.”

Solution 1: Restarting Remote Desktop Service

In some cases, restarting the Remote Desktop Service does the trick, therefore, in this step, we will be manually restarting it. For that:

 
 
 
 

 

  1. Press “Windows” + “R” to open Run prompt.

  2. Type in “services.msc” and press “Enter“.Running Services.msc

  3. Double click on “Remote Desktop Service” and click on “Stop”.

  4. Click on “Start” after waiting for at least 5 seconds.

  5. Check to see if the issue persists.

 

Solution 2: Changing Security of RDP in Group Policy Editor

In some cases, the error message pops up due to your RDP security layer in the Windows group policies. In such scenarios, you will have to force it to use the RDP Security layer. Here’s how to do it:

 
 

 

  1. Go to the Start Menu, search for Local Group Policy and open up ‘Edit group policy’.

  2. Navigate to the following directory:

  3. Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security

  4. On the right-hand side, locate the ‘Require use of specific security layer for remote (RDP) connections’ and double-click it to edit it.

  5. If it is set to ‘Not configured’, select Enabled and then in front of Security Layer, choose RDP.Editing RDP Security Policy

  6. Click Apply and then hit OK.

  7. Restart your system so that the changes take effect.

  8. Try connecting again.
