Just wanted to post a heads-up. There is a conflict between Microsoft's update KB951748 and ZoneAlarm. Something about that update will cause ZoneAlarm to block your browsers from internet access and ultimately shut your connection down. ZoneAlarm is recommending that you uninstall this update as a fix for right now. Turning your ZoneAlarm setting down to "medium" will also fix this problem, but obviously will reduce the level of security provided by the program.
I have a couple of devices at work that require a serial connection in order to properly configure, and, while I do have a couple computers with COM1 ports, they're not exactly accessible to the equipment I need to configure.
