Have a friend local internet also can not use, IIS can not start, but Ping, QQ can also on, this is what reason AH? Is it a virus?
If you are sure that the DNS settings are correct, it is a problem of the virus, many of our machines have experienced similar situation, our solution is to download a green IE repair software (such as Super rabbit IE repair), installation restart press F8 into safe mode of strong repair, Finally the reset after the restart option can also be resolved, the proposed repair with anti-virus software to scan the overall!
Thank you

Remove all your network assistants and try again.
And check your DNS again.
DNS set to your local DNS server address Ah, there are many can ping the Internet is not the problem of DNS. I am usually directly using Google to provide free DNS.
It is easy for ordinary users to use Google DNS because Google has chosen two very simple and easy to remember IP addresses for their DNS servers: "8.8.8.8" and "8.8.4.4". Users simply select these two addresses as DNS servers in the system's network settings. The use of the method is very simple, for broadband dial-up users, in the "Settings"-"network connection" to find a broadband connection, open the network connection properties, select the Interner protocol (TCP/IP) property page, do not choose to automatically obtain DNS, and to select "Use the following DNS server address", The preferred DNS server and alternate DNS server are set to 8.8.8.8 and 8.8.4.4 respectively
Re-install IE or fix it. With Chrome ...
