I was pretty sad about not getting that network usage icon in the bottom right corner of my task bar when my OS changed from XP to Windows 7. However, I just now found something even better, Resource Monitor. I'm still not clear on how I got it to start up, but it not only shows memory and network usage, but what task is accessing the network and where they are trying to access!
I began checking some of the addresses being accessed. One of them was a suspicious-looking 239.255.255.250. It turns out that this is a M$ kludge for discovering plug-and-play services on the network? Who would do such a terrible thing?!!
