How do I power on the host computer from the viewer computer? From the viewer computer, we tried using the power control function but could not get the “Authentication My remote PC” window to pop up nor the “Power Control window” pop up-the viewer computer just kept trying to connect to the host computer. Normally the host computer is powered on and we can just go to full control mode, but the host computer was powered off and we need to know how to turn on the computer remotely, please.
