Hi all, can anyone recommend a good 'network monitoring' tool? Its for a faily small network of 60 machines split over 2 sites via a wireless bridge. Sometimes the network is hammered and we have no real visability of what is causing the problem other than Holmes style guesswork. Last time it was due to some heaving image transfers between sites but as our phone system also runs over the connection we need to have better visability of such areas. Ideally, it would provide a graphic picture of bottlenecks and even better, provide visability of large file transfers to help pin point problems etc.
Thanks in advance
