On server operating systems, TeamViewer operates without any special adaptation.
However, please make sure to activate the Enhanced multi-user support Option (activated by default for TeamViewer 9 and later) in the Options under Advanced.
This option generates an individual TeamViewer ID for every user who connects to the server using Remote Desktop (RDP) by Microsoft as well as for the physical console. Therefore, parallel and individual work of each session is possible.
The Info Dialog now displays two different IDs:
TeamViewer ID of the console of the server operating system (as if one were physically sitting in front of the server)
TeamViewer ID of the user logged into this server using RDP.
