Use a sniffer and watch which ports are being used. I cannot tell you which ports, because the corporate firewall that I manage is not SuSEs Firewall2, but I have only defined which ports to accept outbound (SMTP, HTTP(S), etc) and Kazaa does not work here.
The problem is that these programs can change ports. Even well known ports like 80 443 25 etc may be used. I don't know if Kazaa can do this but I have seen programs speaking perfect http over port 80 that are in no other way related to the www.
Not very useful maybe, but talking with users to have them stop using Kazaa is i think more complicated.
It may be the only effective way.
