Lab Traffic Generator ?

Hi,
it is nice to be able to generate traffic to test smth from time to
time. I used to use tfgen.exe, a small app that can send udp packets
to a destination with some easy control for BW. Sadly, it backfires
on w2k3 server.

I know of many ways to generate traffic, but most are involved.
Nice for detailed type of traffic, but cumbersome for the quick test.

Anybody has a quick and easy like tfgen ? Ideal app would be windows
based, select udp dest port, BW, fire! :)

TIA,
-Carlos
