Does anyone know of a good network analyzer for windows?

 

I find when I hit a bottleneck either in downloading/uploading I tend to use some pretty rudimentary techniques for trying to figure out the source - cap something else and see if it boots the speed of the problem connection by a comparable amount.

 

This is pretty ineffective, and I also would really like to know what the through-put is on the various apps I have running on my computer. I use the free ZoneAlarm for my firewall which at least sort of knows what's accessing the net, but I'd really like something more robust.

 

 

Anyone have any suggestions?

Wireshark is good, although it's a bit lower-level than you want.

Nmap's a good Linux tool that's been ported to windoze....

I already use that for packet sniffing, but I am thinking of something more like the Task Manager process view with networking in/out statistics, so I can see if any given app is hogging the bandwidth, and if a slow transfer is due to my bandwidth maxing out, or the remote host being slow.
