How do you allow "the firewall client to channel port 80 and 443 stuff"?
I don't know how to do that.

        I've had the same problem, at a couple of sites, one of them use
IE on some machines, and FireFox on others. It's interesting to note,
that I have not had a single complaint from a firefox user about this
'Internet unreachable' issue, only from IE users. Installing the ISA
firewall client, and allowing the firewall client to channel port 80 and
443 stuff has made it virtually disappear on all but a couple of
machines.
         
        The couple of machines where this has not worked is driving me
crazy.

        Looking at the logs some more, there are more differences than I
thought...

         

        Here are two of the entries...  The first one is when trying to
go to cnn.com; the second is going to cnn.com after restarting IE.

        Just ran into the problem again on my computer.  Checked the
logs, and it is properly authenticating, resolving the DNS name,
everything looks good except it is trying to use the normal Port 80
instead of using the proxy.  Next time it happens I'll try the
autoconfig URL and see if that clears it up.

        Nope, that is disabled.

        Are you running the ISA SP 2 Compression?

        Yes, that does look like what is happening.  I had one a few
minutes ago that I started diagnosing, it kept coming up as host not
found, then all of a sudden it started working again (before I could
finish trouble-shooting).  Maybe not an IE-specific problem?  Maybe we
just notice it more because IE makes more DNS calls than anything
else...

         Yes,I have see this exact thing, IE acted to me like DNS lookup
was failing? I also had php errors on some site which is probably a
different issue.

        Anyone else experiencing this lately?  Browsing the Internet is
working fine, then all of a sudden nothing loads at all...  You hit
refresh and it sits there for awhile then finally comes up with an
ISA-generated error page saying the site is unavailable.   You exit IE,
re-open it, everything works again...

         

        I don't think it is the ISA2004 server, as restarting IE fixes
the problem temporarily.  I thought it was just an issue with my
computer, as I'm running IE7 RC1, but many other people are reporting
the same problem now.  I've been using my laptop (with all the same
software) at home with no problems, so I'm wondering if there is some
patch for IE that came out recently that doesn't like proxy servers...

         

        Just wondering if anyone else has seen this symptom...  Next
time I run into it I'll do some more diagnostics.
