So, this week I got upgraded to a new PC at work, and switched from Windows XP to Windows 8. For the past couple of days I've been having a problem with Internet access. The computer will lose Internet connectivity for like half a minute or so, and when it comes back, everything will be back to normal except that I'll be unable to access Gmail, and instead will get a "server not found" error. (Occasionally Facebook is also affected.) This happens regardless of which browser I'm using - Firefox, Chrome, IE all the same. All other sites work as normal. Outlook accesses our Exchange server normally. Rebooting my system fixes the problem temporarily, but nothing else I've tried (releasing and renewing my IP address, clearing cookies or browser cache, turning off the Norton firewall, etc.) works. I updated my drivers but this does not solve the problem. Anyone have any idea what the issue here might be?
