I want to control my wife's computer at home from any other location where I may have access to a computer. This might be at work, or from my laptop if I am out of town. The host computer (my wife's I guess) does not have a fixed IP address. Can I have the administrative program on a flash drive, so that I can access and control the home host computer from wherever I am?
What service should I purchase to accomplish this?
Many thanks.
John
