To be able to access your host PC from a remote client computer, you need to ensure that your host PC meets the three following conditions:
The host PC is turned on.
The host PC is connected to the Internet with a live connection.
The GoToMyPC service is running.
Note: To help ensure security, you may want to lock your PC before you leave it unattended.
Note: Since GoToMyPC does not require the display monitor on your host PC, you may want to turn it off before you leave to conserve energy. You can also set your monitor to automatically power down after a specified time in the Display Properties control panel.
