I have a problem with ZoneAlarm configuration. My computer runs a rebranded version of ZoneAlarm behind a router. My computer is configured to go into sleep mode after a period of inactivity. When it comes out of sleep mode, programs on the computer will generally be unable to access the Internet. However, I would still be able visit recently-visited websites from my browser. That, and other symptoms, points to DNS lookup failure as the immediate cause of the problem.
I've had this problem before with some versions of ZoneAlarm, but through upgrading/reinstalling/tweaking somehow the problem went away. I don't know what config options cause the problem to appear/disappear. One thing, the automatic lock feature is off.
Can someone help?
