A few days ago, i found a small problem, but the effect is so big. My company adviser have win 7 laptop, which could not browse to the internet, but it can ping to any website. I have check all of the security issued, but nothing is wrong.

I search this issue in google, and found something useful. It is the WINSOCK problem, a windows service which provide network communication.  The solution is :

  1. Open Command Prompt, on the Accessories tab, and right click, choose run as administrator
  2. Type “netsh winsock reset catalog“, press enter
  3. After that, the system will ask you to reboot the computer. Reboot it.

And after reboot, everything back to normal.
