Hey Gary,
Since you only inquired about a traffic *generator*, the command prompt
(ping 2nn.x.y.z) is your most basic in windows. ;-)
I know that you're far too intelligent to have "upgraded" to Vista, but if
you bought something new recently that came preloaded with the junk, I have
found that you have to disable the firewall in order to be able to observe
any incoming unicast echo replies to the outbound mcast echo requests
(they're visible in protocol analyzer trace files no matter what, but if you
want to see the "reply" on the command prompt, you have to disable or figure
out how to tweak the firewall). You may also have to specify your source
interface/IP in the ping command, depending on your lab topology. This
would be useful if you had issued the 'ip igmp join-group 2nn.x.y.z' command
on some interface and you're trying to ping across the network to test your
mcast configuration. Of course, most folks just do that from another router
or switch in the topology.
As far as the other recommendations, I have found VLC to be fun to play with
and a reasonably good way to actually test mcast capability in production
networks. It's been several years back so I'm a little fuzzy at this point,
but I once needed to build out mcast for an upcoming satellite feed that was
to be distributed throughout the enterprise at a scheduled time. As I
recall, I set up VLC to actually put some video across what I had configured
so that I could observe not only connectivity, but also perceived quality
(had some MLPPP load sharing and stuff that was a concern).

To test out PIM scenarios configured on the homerack Im looking for a simple
windows based multicast traffic generator.
Can anyone recommend a good one?
Thanks
