How can you control a computer on your home network from another computer on your home network?

If you download the free version of VNC it will not be compatible with windows 7. I would reccomend TeamViewer. It's a well known software application and is dead easy to setup. Will work over a home network or the internet from anywhere or any computer. You will need to install Teamviewer on both PC's and also sign up for a free account. Then add both pc's to your account. When ever you open teamviewer you will see a list of all computers on you're account and clicking on them will give you control of that pc. And it works both ways whichever PC you're at. Also if for some reason you happen to find yourself at an internet cafe for example, and you're computers are on at home but not logged in, you can go to the teamviewer website and log into your account. You will see the same list of pc's in the browser window and clicking on them will give you access just like before.

VNC software. I use RealVNC. It's probably still free for small networks. Been using it for years. You don't need any online services either. I can control any PC on my network from any internet connection also. You don't need team viewer or logmein bullshit.
