The error notice “An internal error has occurred” for Remote Desktop Connection is quite ambiguous. It usually happens when a user attempts to connect to a remote computer. This could be due to a faulty network connection, an incorrect remote connection configuration, and more.

RDP error – An internal error has occurred

The following are some of the known working methods for resolving the RDC problem in Windows 11/10:

1. Make the necessary adjustments.

2. Disconnect from any VPN connections.

3. Rejoin a domain after leaving it.

4. Make use of the Local Security Policy tool.

5. Disable Network Level Authentication by changing the MTU value

To carry out these recommendations, you’ll need an administrator account.

1] Configure the settings

Search for the Remote Desktop Connection client in the Windows Search box to launch it.

From the bottom left corner of the screen, select the Show Options button. To get started, go to the Experience tab.

Uncheck the box labeled Reconnect if the connection is lost.

2] Turn off any VPN Connections

Open the Settings app on Windows 10. Go down the following path: Network & Internet > VPN

Select Disconnect from the VPN network to which your computer is connected.

If you’re using any third-party VPN software, make sure it’s turned off.

3] Leave and re-join a domain

Use the steps below to remove a system from the domain:

1. Open the Settings app by pressing the Start button.

2. Go to System > Accounts > Access work or school.

3. Choose the organization from which you want to disconnect your computer.

4. To disconnect from the organization, select Disconnect.

5. Restart your computer.

The system would be disconnected from the domain as a result of this.

4] Use the Local Security Policy utility

Select the suitable result after searching for Local Security Policy. In the left-hand navigation panel, go to Local Policies > Security Options.

On the right-side panel, double click on System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing.

The configuration dialog will appear.

Select Enabled. Select OK after selecting Apply.

Restart your computer to see if the problem has been resolved.

5] Change MTU Value

The maximum transmission unit, or MTU, is a measurement of the largest data packet that a network device can accept. If the data amount is raised, the chances of a connection drop are reduced. While Windows does not provide a direct solution, you can utilize the TCP optimizer tool to adjust the MTU value, which is available here.

To enable the MTU box, select custom mode and then increase the size. It’s possible that you’ll have to explore a little to find the proper value to fix the problem.

6] Disable Network Level Authentication

1. Go to the Windows Settings menu by pressing Window + I.

2. Select System > Remote Desktop from the drop-down menu.

3. Uncheck the option that says “Allow connections only from computers running Remote Desktop with Network Level Authentication.”

4. Close the configuration windows.

Now try connecting to a remote desktop to see if that fixes the problem.

Is higher or lower MTU better?

While a larger MTUY can transport more data, the data can get fragmented if it is too large. To figure out what works between your router and your computer, you’ll have to experiment with different values.

Why is the Remote Desktop connection not working?

Even if your password is accurate, there could be a variety of reasons. Network difficulties, server-side authentication issues, Firewall concerns, and the ability to connect to a computer through remote are just a few of them.

Remote Desktop Connection stops all of a sudden

If this happens frequently, you might want to minimize the number of connected devices that use the connection. Printers, audio playback settings, and other items are included. The simplest approach to figure this out is to start with the most basic option and gradually increase it.

I hope you found the article easy to follow and that you were able to figure out why you were getting an internal error when using Remote Desktop.
