Ive noticed that every now and then, my cable modem goes crazy for a few minutes. Ive no idea why, as Im not doing anything when it happens. Its just started doing it again, so I turned off every program that I could think of that could be legitimately using the connection (firefox, skype, xfire etc), but it persisted. I checked the network usage tab in task manager, and its definately doing something fairly significant.

Short of going through taskmanager closing things willy-nilly untill it stops, I cant think of any way of tracing the problem. Anyone got a more reliable solution?

some kind of port scanner or packet sniffer would probably be your best bet

try sysinternals (if they're still up) or download.com

it'll monitor all network activity and you can look through it


has quite a good definitions set too
