Windows Server with TV Host deployment - unattended remote support

Helo,

I'm confused. I deployed a TV host on a Windows Server. Device is assigned and I can see this device on my devices list with the name set during the assignment process. If I connect to this device I see Windows login screen. To login in I need to provide a username and password - it is understandable - this works like a RDP connection in this case. On the server I have a user logged in and active. TV Host shows ID for server and also ID for this active user session. How to connect to this user session with unattended remote support? I can even find anywhere user TV ID except TV host on this Windows maschine. TV knows user ID and password, if a copy this data to my TV I can connect successfully but why I can find how to connect to this session unattended?

Best regards,
Radek
