Use These Fixes to Troubleshoot The RDP Internal Error
The internal error of RDP requires manual troubleshooting and will stick to your screen until the cause has been addressed. Mentioned below, we have included the best and most effective troubleshooting methods for this error.
Allow Access From Public Network
If the error comes on your screen when you are creating the remote connection from a public wi-fi, then there is a good chance that RDP has been denied permission for the public network. If this is the cause, then you can fix it by following the mentioned below steps.
- Open the Control Panel on your system.
- Go to the System and Security then Windows Defender Firewall.
- Click on “Allow an application or feature through Windows Defender Firewall” from the left side sidebar.
- Locate your remote desktop client and allow for public networks.
The Windows Defender Firewall of your system will not allow you to create a remote connection on a public network if the client is not authorized to use it. However, by following the steps, you can allow access. Do note that if the public network is slow, then you will not be able to run the remote session.
Restart The Application
By restarting the application, we don’t mean for you to just close the application and start it again, as it is not going to solve the RDP internal error. Closing and opening the application back again is not enough to shut the servers down and get them back up and running again.
Follow the mentioned below steps to restart the remote desktop service the correct way.
- Press the Windows Key + R to open the Run dialogue box.
- Type the command compmgmt.msc and press Enter.
- In the Computer Management console, go to the Service and Application tab.
- Locate the Remote Desktop Service option and restart it.
By restarting the application through this way, you will restart all its programs along with the servers. If the error has happened because of server exhaustion or overload, then this shall fix it.
Check For Windows and Drivers Update
If you are trying to run a remote connection on a system with outdated windows or drivers, then the process is likely to fail and showing you the RDP internal error message. You can start by checking whether there are any pending windows updates or not by going to Settings > Update & Security > Windows Update.
After updating the windows, you should also check whether there are any updates for the driver or not. Go to the Device Manager and update the drivers of the remote desktop client.
Outdated windows and drivers can raise a number of alarms, including RDP internal error, when creating a remote connection. However, after updating them, the error will be addressed and you will be able to create a new remote session.
Look For Clashing Software
If you are running Anti-Virus or other security tools in the background, then there is a possibility that they might have flagged the remote session as suspicious. If this happens, then the application’s access to resources will be blocked, thus showing you the RDP internal error.
To check whether the software is clashing with the remote connection or not, you can start by pausing or stopping the task of the application. After this, you can check to see if the servers are able to start the connection. If they are able to create the connection, then you will need to configure the tool’s settings to allow for remote desktop connection.
Disable Network Level Authentication
Network Level Authentication plays a crucial role when it comes to network security. Although it is an essential feature, it is a known cause for the RDP internal error. In order to disable Network Level Authentication, you will need to do the following:
- Open the Control Panel on your system.
- Go to the System & Security > System and locate Advanced System Settings.

- Once on this panel, go to the Remote tab at the end.
- Uncheck the box right next to the message, “Allow connections only from computers running Remote Desktop with Network Level Authentication”.

By unchecking this box, the RDP internal error message will be fixed. However, make sure that you revert this setting back to enable once you are done with your remote session.
