Hi,
I´ve been using ISA Server 2006 for several years. Since some weeks ago, I´ve had some problems with my service. The problem is with the computers that are configure as a Web Proxy Clients. Can't browse. The Http protocol stop working. Others protocols like SMTP keep working. This happened only with the Web Proxy Clients. The SecureNat Clients keep browsing without any problem. The only solution to this that I found, is restart the Isa Microsoft Firewall Service. It keeps working and this happened again at least every two days.
Any idea of this issue?
Thank You
