Easily Fix “An Internal Error has occurred” Error in Remote Desktop Connection

When you see the error “An internal error has occurred” during a remote desktop session, it’s probably caused by the settings of the RDP. Tweaking the settings of the RDP, or re-establishing the connection with the domain are some of the steps that ensure the solution to this error.

Methods to Fix “An internal error has occurred” Error in Remote Desktop

Fix # 01: Remote Desktop’s Settings

  • Open start menu and type ‘remote desktop connection’ and then open it.
  • Click the ‘Show Options’ button at the bottom. Then head over to the ‘Experience’ tab.
  • At the bottom of this tab, there is an option ‘Reconnect if the connection is dropped’. Make sure it is ticked.

Fix # 02: Re-establishing the Connection with the Domain

We can reconnect to the domain after having disconnected to fix this problem. To do this:

  1. Open start menu and go to ‘Settings’.
  2. Proceed to ‘Accounts’ tab and then select the ‘Access work or school’ tab.
  3. Select the domain that you have connected to and then disconnect from it.
