Added IE as an application, took a lot of fiddling, but did work

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.

        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.
