Suppose another person is running a network scan on the network and my computer belongs to this network.

Are there ways to find who is performing the network scan or know that a network scan is being perform on my network?

This is an exact duplicate of this question: serverfault.com/questions/157785/… . Cannot close as dupe directly, thus voting to move (then close later :-) ). –  sleske Jan 11 '12 at 9:57
And even if it's not an exact dupe (debatable), this question is better suited to serverfault. –  sleske Jan 11 '12 at 9:59
I can't see why it would be better suited for SF. Just connecting your computer with a network is not unique to desktop support and professional networking. This is something a home user can ask themselves as well. –  slhck Jan 11 '12 at 11:17
