Contains notes and information on the installation and configuration of the VNC server on the host PC.


Btn_Top10x10 Topics:


The Remote Desktop Protocol (RDP) is a Microsoft network protocol for the display and control of desktops (PCs) on remote computers (Thin Client). The protocol controls how the terminal services are addressed and used under Microsoft Windows.


With RDP, the PC to be controlled functions as a terminal server. This terminal server generates screen output on the Thin Client. In addition, mouse and keyboard input can be received by the Thin Client. Depending on what it is used for, Thin Client users can monitor or remotely control the workstation of their terminal server (Host PC). RDP manages the transfer of screen content and mouse and keyboard input via the network.




For a connection to the PC to be established in the first place, the connection type RDP with the associated, correct IP address of the PC must be defined in the (Address book ) of the Thin Client.


Click on the relevant button for a detailed description.
