The IGMP protocol is implemented solely within the operating system, and is
used automatically when an application joins a multicast group. (It is not
used when multicast packets get *sent*; only when multicast groups get joined.)
>Anyway to enable IGMP with live.com ??
As I noted above, IGMP is implemented automatically by the OS; it's not
something that higher-level code knows about.
I think that IGMP is a red herring here. Nonetheless, if you're running an
old version of the Linux kernel (if you're running Linux; I forget), then
you should upgrade.
