We upgraded from ISA 2006 to ForeFront about 6 months ago. I upgraded the rules but we saw an error where people would not be able to browse when the would be using two browsers. The first one in use would work and the second would not. If you closed down the browsers it would work whichever were opened first. Our server was damaged by a lightning stike and I setup the rules cleanly without restoring a backup on the new server.

We are having the same kind of issue. Randomly. if you for example are using Internet Explorer the first tab open will work but any other tabs you open will not. Today I had someone using tab 1 on ie 9 and it worked perfect. They had two other tabs open and those would not browse. I looked in the log and I was getting:

Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied.

I closed down the browser reopened and all three tabs worked fine. Any ideas?
