Vnc forcing login screen instead of logged-in user desktop

[lakes97]

Hello,

I have an issue with VNC on Windows Server (never had that issue on Windows 7/10). I installed VNC server and to allow UAC screens input from vnc sessions I wanted to register vnc as service. Everything is fine but while loggin in via vnc viewer, I am forced to use login screen instead of looking at logged-in user desktop. In application mode it works correctly (when any user logged-in, then I can watch its desktop without disturbing), but when I switch to service mode, it automatically chooses to log in from login screen and as a results kicking the other person. Any suggestions, ideas?

The user is using an rdp support session.

Running as application, vnc clone the user desktop.
Running as service, vnc clone the console.

While reading forums, I noticed the explanation that while using running as service, you will see either the desktop of currently logged in user or else the login screen.

When I use running as service on desktops to avoid loosing connection after restart, vnc is showing me the desktop of currently logged-in user.
Here on virtual machine with Windows Server I always get the login screen. Is that because of the fact that more than one person can be logged-in and it will always behave in that way?

If I lack some kind of basic understanding of this whole system, please kindly explain that widerly.

On a rdp server system: console + rdp
On a standard PC: console OR rdp

VNC always clone the console in service mode.
VNC always clone the user session appliaction mode ( this can be the console or rdp session)

BUT:
There is an experimental option (server)
[v]RDPmode
If you connect you first get a speical preconnect screen, showing the active sessions.
Then you can choose what you want ( console, rdp1, rdp2, rdp3..)
