I have a Win7 64bit SP1 pc. It has a strange problem. The browsers (IE8, IE9 and Chrome) report that the DNS is not responding, however I can do to a CMD Prompt and ping web addresses no problem, the DNS correctly resolving the IP address.
I have already reset the Winsock, the TCP IP stack and flushed the DNS cache. I have uninstalled IE9 and still have the same problem in IE8. I have uninstalled my antivirus and made sure windows firewall is off, still no go.
