Hello Dev, welcome to this journal article where we will be discussing the common error faced by administrators while trying to configure the Remote Desktop Session Host (RD Session Host) server. The error message displays “Unable to configure RD Session Host Server Invalid Operation.” We understand this error can be frustrating and time-consuming. Hence, we have come up with this comprehensive guide that will help you fix this issue in no time.
Understanding the Error
Before we dive into the potential solutions, let’s understand the error in detail. This error is often observed when configuring the RD Session Host server to allow multiple users to connect remotely. The configuration process involves adding the RD Session Host server to the Remote Desktop Session Broker (RD Connection Broker).
The error message “Unable to configure RD Session Host Server Invalid Operation” typically occurs due to invalid configuration settings or incorrect permissions or registry settings. The error message, along with the event ID, makes it easier to debug and resolve the issue.
Event ID
Event ID 1359: An error occurred while configuring Remote Desktop Services. The RD Session Host Server Certificate specified is invalid.
Event ID 1357: The Terminal Server Configuration WMI provider has encountered an unexpected error in TerSrvConfig.SaveSettings. Error code 0x8004100e
Event ID 1012: Remote Desktop Session Host server has failed to register the SPN. Error: “The specified domain either does not exist or could not be contacted.”
Potential Solutions
Validate Certificates and SSL Settings
The Remote Desktop Services rely on certificates for secure communication between the server and clients. Therefore, the first step in resolving the error is to verify the validity and configuration of these certificates. To do so, follow the below steps:
- Open the Server Manager and navigate to Remote Desktop Services.
- Click on the RD Session Host Configuration and select the RDP-Tcp connection.
- Click on the General tab and locate the certificate assigned to the connection.
- Verify that the certificate is valid and issued by a trusted certification authority.
- Check whether the Certificate Revocation List (CRL) is accessible and not expired.
- Verify that the SSL settings match the certificate configurations.
If the certificates or SSL settings are invalid, update them with valid configurations and restart the RD Session Host server. Ensure that the RD Session Host server is registered in the Active Directory Domain Services (AD DS) and is assigned appropriate permissions to read and update certificate configurations.
Verify Permissions and Registry Settings
Incorrect permissions and registry settings can cause the error message “Unable to configure RD Session Host Server Invalid Operation.” Therefore, verify that the RD Session Host server is assigned appropriate permissions to write the registry settings, as shown below:
Registry Setting |
Path |
Security Key |
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\SecurityLayer |
Certificate Key |
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\Triple DES 168 |
Additionally, ensure that the RD Session Host server is configured to use the correct RDP-Tcp listener settings. Follow the below steps to verify the listener settings:
- Open the Server Manager and navigate to Remote Desktop Services.
- Click on the RD Session Host Configuration and select the RDP-Tcp connection.
- Click on the General tab and ensure the Network Adapter drop-down box displays the correct network adapter.
If the permissions and registry settings are incorrect, modify them with the appropriate values and restart the RD Session Host server. It is also important to ensure that the Remote Desktop Services are running with the correct startup type and dependencies.
