Are you running the ISA SP 2 Compression? -Wayne _____ From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of Ball, Dan Sent: Monday, October 02, 2006 8:21 AM To: isalist@xxxxxxxxxxxxx Subject: [isalist] Re: IE Problems? 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. _____ From: isalist-bounce@xxxxxxxxxxxxx [mailto:isalist-bounce@xxxxxxxxxxxxx] On Behalf Of James May Sent: Monday, October 02, 2006 10:24 AM To: isalist@xxxxxxxxxxxxx Subject: [isalist] Re: IE Problems? 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.

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.
