Windows XP

To see multicast group memberships in Windows XP, you can use netsh :

U:>netsh interface ip show joins
Interface Addr   Multicast Group
---------------  ---------------
192.168.139.1    224.0.0.1
192.168.137.1    224.0.0.1
192.168.136.1    224.0.0.1

Solaris (and probably other Unixen as well)

In Solaris, the netstat command can be used :

$ netstat -g
Group Memberships: IPv4
Interface Group                RefCnt
--------- -------------------- ------
