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.
