Hi guys, I'm on XP SP3 and not using ZoneAlarm. When the problem has occurred, Firefox, IE and Thunderbird (which is using the WebMail plugin) are all affected. Disabling the Web Shield gets these working again, as well as going into my Network Connections and disabling then enabling my Local Area Connection. I tend to do the latter as sometimes Web Shield gets hung up and won't restart properly. https pages (port 443) don't seem to be affected as I can connect to my work web portal at the time the problem is happening.
As for the latest version - I did not experience the problem last night running Firefox, Ventrilo, Ventrilo server and Guild Wars for a couple of hours. I'm still hoping that this update might have solved things on XP but it's unfortunate to see that you folks on Vista still have the issue. The biggest test for me would be seeing what happens on Friday and Saturday nights.
Vlk, if a lockup occurs should we capture a dump of the ashWebSv.exe process?
