I am having a problem with getting on to the internet after my computer has been on a while.
I have a Dell Dimension 3000, pentium 4, HT, Windows XP Home (legitimate), 160G hard drive, Comcast cable modem, ZoneAlarm Security Suite.
I do fine when I start my computer up, and as long as I am working, everything is fine, but if I leave the computer running afterwards for any length of time, it loses its ability to go online, and I get "Cannot Find Server", and "Page Cannot Be Displayed" notices, after timing out trying to reach sites. I can only work offline.
I have to turn the computer off, and then back on and everything is fine again, until I leave it running without working it for a while, maybe and hour or so. Has anyone run into this problem? Any ideas on how to fix? I suspect ZoneAlarm, but I don't know that for sure.
Any help would be greatly appreciated.
