I have just implemented ISA server over W2K on my network, but Kazza is not connecting...(MSN can connect) I don´t know how configure it? Also some webpages like the section Games on www.yahoo.com have conection problems... I think can I fix the problem if I define protocols Socks5 or Socks4 on ISA Server, but I don´t know how can I do it...! Thanks in advance. Rubén Dusso
