There are ways that are not illegal. If you know the static ip address for the computer you can log on it. Just go to search and type in remote. Then find ''Remote Desktop Connection'' right click and send to desktop. Then just click on the icon and type in the ip address here you will be able to access the other computer.

Hope this helps..
There are programs that do this, but you need to have admin access to do it. Even then, the admins of the net can track what is being done and you would not be in good shape afterwards. I would not suggest you do this. What you could do is send a msg to the IP using the net send command. Go to start, Run and type in cmd and when the cmd window pops up, put net send /? and that will give you the details you need to know to send it.
