Hi, I m providing internet access to 25 PCs using ISA. The problem is many internet applications like Napster, Audio Glaxy, MOrphieus etc are not connecting to the their respective servers. Also web embedded chat zones are also not working (like that of desichat.com). please can any one help me in configuring these applications. I need to know port settings for their outbound request (i.e. how can i create packet filters for these applications). And please do tell me that whether i need to set proxy in these applications installed at my clients PCs or not if i create packet filters for them. Thanks, Arsalan. __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo! Personals. http://personals.yahoo.com
