I have a Windows 7 machine that can't access the internet through a browser (IE or Firefox) and other applications (Thunderbird, AVG Update) can't access the internet. However, I can open a command prompt and ping yahoo.com.
I have flushed the DNS and registered the DNS and it has not helped. Browser error messages refer to DNS. I can't get to the gateway in the browser either (192.168.1.254).
I can access the computer remotely.
Can somebody give me other things to check. The user can't tell me what they did to break it. It was working a week ago and now it isn't.
There is no third party firewall, just the Windows firewall.
