i was on my friends pc and something weird happen i lost control of everything.......the notepad program poped up and say "hi mike"
later on my friend was telling me how he is was using his other pc downstairs and somehow he can gain access to other pcs because of the router

can someone show me how to do this?

i have two pcs using the same router but one has windows 98 and the other windows xp

was it 'notepad', wordpad, or windows messenger?
and what would you do IF I tell you how?
I don't want to assist anyone in causing serious trouble, but a harmless prank would be ok.
And why didn't/don't you ask your friend to show you? Hands on is always easier to explain.

1. it was notepad
2. im only going to use it on my own pcs
3. im just going to use it on my bro and his friends
4. im deaf and he was working on a engine swap, he tried to explain it but i couldnt read his lips very well
