I've been meaning to post this one for awhile but am just now getting around to it. I plug my laptop into the network at work so I can monitor the various forums, check my personal e-mail through the day and download any virus definition updates (they come in pretty much daily). I use the freeware version of ZoneAlarm and, when I first start connecting to the Internet on my laptop, all is well. I periodically do other things (like work) and inevitably, at some point during the day, I'll try to open my browser (IEv6) and get a blank page then the typical can't find server error. I don't get a message from ZoneAlarm saying it's blocked anything...nothing. I turn off ZoneAlarm and abruptly am able to connect to the web again. I suspect some sort of conflict between the network firewall (Cisco PIX) and my little machine but why does it work at first and then die later on? Just thought I'd mine the experience here on the board. Thanks.
