Hi all,
I'm back after a long break from backtrack.
Originally I used it to prove how insecure our WEP network was! but now I have a new problem that I hope Backtrack can help me with.

Our office consists of many PC's, using D-Link Switches to connect to our router using ethernet (we binned wireless).

recently out network has been sapped at seemingly random intervals during the day. With pings to bbc reaching 1500ms. My aim is is to pinpoint where the bandwidth is going! and to which PC.

Is there a way that backtrack can help me with this. A solution or a point in the right direction would be much appreciated and lesson my time on google.
