Fix Winsock


  Once a virus is stripped out of the system, I have incurred issues with networking where replacing network drivers does not work. The issue was that the network adaptor would not get a correct IP assigned to it. The DHCP request for an IP fails and the adaptor appears to be broke. On a couple of occasions Microsoft document KB299357 was used to restore internet access. It resets the WinSock , but be warned it could affect your software firewall, Proxy, and antivirus/spyware settings.

Use the Command Prompt:

netsh winsock reset

once done, restart the computer.
