Hello Nimi,

Thank you for your question and for reaching out with your question today.

Event ID 1012 in the System log on a Windows Server indicates that the Remote Desktop Services session has been disconnected due to a licensing issue. This event is logged when the Remote Desktop Session Host (RDSH) server cannot contact the Remote Desktop Licensing (RDL) server or encounters a problem with licensing.

The licensing issue can prevent users from successfully logging in and result in a black screen with no desktop, taskbar, or cursor visible. The server is unable to validate the user's Remote Desktop Services license, which leads to the session being disconnected.

To resolve this issue, you can try the following steps:

1. Ensure that the Remote Desktop Licensing server is reachable and properly configured. Check the RDSH server's licensing settings to ensure it is pointing to the correct licensing server.
2. Restart the Remote Desktop Licensing service on the licensing server. This can help refresh the licensing configuration and resolve any temporary issues.
3. Verify network connectivity between the RDSH server and the licensing server. Ensure that there are no firewall or network configuration issues preventing communication between the two servers.
4. Ensure that you have sufficient Remote Desktop Services licenses available on the licensing server for the number of concurrent connections you require. Check the license usage and available permits to confirm that you are not exceeding the license limit.
5. Check if the Remote Desktop Services licensing certificate on the licensing server has expired. If it has, renew the certificate and update the licensing configuration on the RDSH server.

It's also recommended to review the Event Viewer logs on both the RDSH server and the licensing server for any related events or errors that could provide further insights into the licensing issue.

I guess, the events you found in security logs and the blank login screen issue are different. The first issue mostly can be solved by a restart.

There are some situations where you miss the UI after changing/uninstalling/installing some of the features of windows. The following command can fix that issue

Dism /online /enable-feature /all /featurename:Server-Gui-Mgmt /featurename:Server-Gui-Shell /featurename:ServerCore-FullServer
