Exactly how is IE configured?
Those log entries show successful connections.

ISA resolves names for browsers configured as web proxy clients, so if the browser is complaining about "DNS Failure", it's likely
that it can't resolve the proxy name.

This is what was in the log.  The error that comes up in web browser is the
Page Cannot Be Displayed, cannot find server or DNS Error.  I'm thinking it
must be a DNS error, but the DNS error probably has something to do with ISA
blocking a DNS request?
