ISA 2004 http errors?

Recently we've been fighting some new converted ISA 2004 clients with some miscellaneous browser errors that users are getting from http. Here's something that helped us to diagnose the problems and might help you as well.

One thing that is just downright powerful now in ISA 2004 is the monitoring aspect. The monitoring agent is just plain stupid good. It works excellent. However you might not see everything that you can by default and that could limit you in your troubleshooting if you didn't know everything was there.

On the monitoring piece and then the logging tab of course you can select from many different queries to really deduce what a problem could be. However make sure you see what will help you in the results. Right click on the display results bar and you'll see an option to add/remove columns as many Microsoft programs now have. Now choose for instance the HTTP status code option and right away you'll see when users are getting nasty http errors and what they are. This might help you get a quicker fix in place.
