ISA 2004 Windows 2003 Server XP client running firewall client or web proxy Should I be getting 88% dropped packets on my external nic. This is a test server and only has one user attached. I am also still having problem with a few websites. (Dell, Wal-Mart, Yahoo inbox) Sometimes they work sometimes they do not. NsLookup works on all these sites. Could this dropped packets issue be the cause or does this just show that the firewall is working correctly.
