Common Windows RDP Server Errors and How to Fix Them

Remote Desktop Protocol (RDP) is a vital tool for businesses and individuals who need remote access to Windows servers. It allows users to manage their systems from anywhere, enhancing productivity and flexibility. However, users often encounter various RDP errors that can disrupt their workflow. These issues can arise due to network problems, misconfigurations, or security restrictions.

If you frequently face RDP connection issues, understanding the causes and their solutions can help you resolve them quickly. Below, we will discuss some of the most common Windows RDP server errors and the steps to fix them efficiently.

1. Remote Desktop Can’t Connect to the Remote Computer

One of the most frustrating errors occurs when you try to establish a connection, but your device fails to connect to the remote server. This issue may stem from multiple factors such as network connectivity problems, disabled RDP settings, or firewall restrictions.

Solution:

Ensure that the remote server is powered on and connected to the internet.

Verify that the RDP feature is enabled on the remote computer by navigating to Settings > System > Remote Desktop and ensuring that Remote Desktop is turned on.

Check the firewall settings to ensure that port 3389 is open, as this is required for RDP connections.

Restart the Remote Desktop Services by running services.msc and finding Remote Desktop Services, then restarting it.

2. CredSSP Encryption Oracle Remediation Error

This error occurs due to security updates that prevent insecure RDP connections. It happens when the client and server have different security configurations.

Solution:

On the client system, open the Local Group Policy Editor by typing gpedit.msc in the Run command.

Navigate to Computer Configuration > Administrative Templates > System > Credentials Delegation.

Locate Encryption Oracle Remediation, enable it, and set it to Vulnerable.

If using the registry editor, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters and modify the AllowEncryptionOracle value to 2.

3. The Remote Computer Requires Network Level Authentication (NLA)

Network Level Authentication (NLA) adds an extra layer of security by requiring authentication before an RDP session is established. If your client does not support NLA or if it is incorrectly configured, you may face connectivity issues.

Solution:

Open the Run dialog (Win + R), type sysdm.cpl, and press Enter.

Go to the Remote tab and uncheck "Allow connections only from computers running Remote Desktop with Network Level Authentication" if necessary.

Alternatively, update your RDP client to support NLA.

4. “An Internal Error Has Occurred”

This generic error can be caused by incorrect RDP settings, system updates, or DNS issues.

Solution:

Restart both the local and remote systems.

Open Local Group Policy Editor and navigate to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security.

Locate Require use of specific security layer for remote (RDP) connections, set it to Enabled, and choose RDP as the security layer.

Check your DNS settings and flush the DNS cache using the command: ipconfig /flushdns.

5. Remote Desktop License Errors

License errors usually occur when the RDP session limit is exceeded or when there are issues with the Remote Desktop Licensing configuration.

Solution:

Restart the Remote Desktop Licensing service by running services.msc.

Check the licensing mode under Local Group Policy Editor > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Licensing.

If necessary, remove the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing registry key and restart the system.

6. The RDP Session Ended Due to Protocol Error

This error typically happens due to compatibility issues between the client and server.

Solution:

Ensure that both the client and server are updated with the latest Windows updates.

Try connecting using a different RDP client.

Adjust the RDP session settings in Group Policy Editor under Remote Desktop Session Host by setting the Limit Maximum Color Depth to 16-bit.

7. Black Screen After Login

Sometimes, after successfully logging into an RDP session, users may see a black screen instead of the desktop. This can be caused by display settings, outdated graphics drivers, or a slow network connection.

Solution:

Press Ctrl + Alt + End and open Task Manager. Restart the Windows Explorer process.

Update the graphics drivers on both the client and server machines.

Check your internet connection and ensure it is stable.

Modify the RDP Display settings to Disable Persistent Bitmap Caching before connecting.
