The Microsoft Terminal Services Client ActiveX control (also known as Microsoft RDP Client Control) Is ActiveX is component offered by the server This is a downloadable ActiveX control provides nearly the same functionality as the full Terminal Services Client, but is designed to deliver this functionality over the Web. The ActiveX control does not come installed as part of any Windows client system. Instead, clients obtain the control from web servers that offer terminal services. The configuration process that enables an IIS server to provide terminal services involves installing on the server a file containing the control. The server then delivers this file to any client system that needs it, and the client installs the control
