Access Running RDP Sessions

[MitchMiller]

I installed Team Viewer on a Windows 2012 R2 Server. I know there is a session ID for each RDP connection and an ID that let's me get to the server where I can actually login with an account. Is there a way to remotely control an active RDP session? Meaning if one of my end users is on the server doing some work do I have to ask them for their ID or is it view-able somewhere so I can just hop right on with them?

I find that there is ONE id for all RDP sessions

If the user in the session activates teamviewer, then you can connect to that session

(Or you can connect to the 'client' hosting the RDP session)
