2026.3.x - Terminal Services console no longer works

Hi all

I use the "Terminal Services console" tool under the "System administration" category very frequently to manage and, if necessary, log off users logged into a server.
Since upgrading to version 2026.3.x (currently 2026.3.9.0), I receive the following error message when launching the tool:
"Unable to retrieve Terminal sessions; verify your credentials."
In the properties of the host object, under Management tools -> Tools -> Credentials, I have enabled "Use session credentials". I have also tried using "Username and password" with the credentials of a Domain Administrator. Unfortunately, without success.
A simple RDP connection works without any issues.

I am running the application with a user who also has administrator privileges on the target host.

What can I do to fix this?
