I am trying to allow my client to use Mac OS X 10.2.8 on a Microsoft Small Business Server 2000 network. I am using ISA Server 2000 as their Firewall. I can get onto the Internet from the internal network if I constantly enter a username and password in a browser, but automatic updates and other features through the firewall are not available--being blocked by ISA. How do I make the Mac a true firewall client? Thanks. Shane Hicks
