This error indicates a problem within the Remote Desktop Protocol (RDP) service, often due to misconfigurations or conflicting settings. The most common cause of this issue is a discrepancy in the Security layer settings between the client and the server. Other potential causes include issues with the Remote Desktop service itself or network-related problems such as VPN conflicts or firewall restrictions. Now that we know the details and causes of this particular issue, let’s proceed with resolving this error.
1. Change RDP Security Settings
Restrictive and incompatible group policy configurations can sometimes interfere with Remote Desktop connections. Specifically, setting the “Require use of specific security layer for remote (RDP) connections” policy to Enabled and selecting RDP as the security layer mitigates conflicts that can arise from the default or improperly configured settings.
2. Allow Remote Connections
If the ‘Allow Remote connection’ option is not enabled, Windows will block external connections as a security precaution. Enabling this option ensures that the system can accept remote desktop requests, which is often a necessary change to resolve related errors.
3. Enable “Reconnect If Connection Drops” Option
The Remote Desktop Connection client includes an option that allows users to automatically reconnect upon an unexpected disconnection. When this option is activated, the RDP client automatically attempts to re-establish a session without user intervention should the connection momentarily drop. This could potentially bypass temporary network glitches that could otherwise result in an internal error notification.
4. Delete MachineKeys
MachineKeys are important for creating secure communication channels between systems, such as when utilizing Remote Desktop. If these keys become corrupted, the secure channel may fail to establish, prompting the internal error. Removing the corrupt MachineKeys and forces the system to regenerate new, better ones, that may resolve the problem.
5. Restart Remote Desktop Service
The Remote Desktop Service is essential for all RDP related processes. If it’s not functioning correctly, it could cause the error. Sometimes, this service might encounter issues or bugs that prevent it from operating correctly. Restarting the service can re-establish RDP connections that may resolve the problem.
6. Disable VPN
VPN(s) modify your network routing, which can create conflicts or restrictions in connecting to remote systems. Therefore, you must disable your VPN if you want to connect to another computer through RDP succesfully.
