> Sorry, never saw source code for IGMP. It is very similar to ICMP. As MS doesn't offer IGMP functionality packed as a DLL (as it does for the ICMP), I think my only option (besides dropping to the WinPcap level) is to use SetSockOpt - similar to the way you already hadle MultiCast = true. My next problem is this - MCAST_JOIN_GROUP requires me to pass a GROUP_REQ structure which contains the following member: gr_interface The interface index of the local interface on which the multicast group should be joined or dropped. Is this something I can retrieve using ICS or do I have to call GetAdaptersAddresses, parse the output and find the appropriate network interface?
