net send

Heh, Yeah I host myself and I see a few morons scanning my site now and then looking for volnerbilities (they just end up getting auto banned no biggie) But yeah I know you can NET SEND to other computers on you're network, but how would you go about NET SENDing to other computer not on you're network, don't you need to know their computer name or something.
or would it just be ..
net send [iphere] [message here]

I'd like to message those morons and laugh =( - Sounds stupid eh?

its done by the ip address of the computer

So you don;t need to know their ComputerName aswell?

nope, but if they are running a firewall, they will not get the message...
