I'm probably just overreacting, but I recently came across a LAN-scanner that showed me the option "remote shutdown", for all found computers on the scanned network.
Now, how exactly does this work? If I send such a message, will the shutdown happen no matter what, or is it required to have the password/user-name of the user of that other computer.
Mostly I'm wondering: can this be done to me and how do I prevent it?
EDIT: what's more, I had the scanner check for shares. The result being this: Double clicking the links opens them in explorer, basically meaning my entire C and F drive(only 2 HD's I have) are completely exposed to anyone in my LAN. Or can I open these because it's my own machine?
