I have windows 2003 and ISA server 2006 for sharing internet in an office with 200 pcs and for shaping the bandwidth I'm using bandwidth control management (the very old version) and I have a client which I know who is he, when I shaped his bandwidth to 32kbps he still able to download with the whole bandwidth's speed but when I shape his bandwidth to 1bit he is not able to do anything thus it shows he is trying to bypass the shaping rule and he is successful.
first of I want to know what kind of software or trick does he uses?(because he is one the top manager of out organization I can't access to his computer directly) second I want to how can I defend this kind of trick?
regards.
