and download the LSP-Fix
from it's download location.
LSP-Fix is a utility designed to remove and repair problems associated with a a type of software called a Layered Service Provider, or LSP. LSPs are designed to integrate directly into your TCP/IP layer, the protocol you use to communicate on the Internet, in order to manipulate data that is sent across it. The LSPs are installed in such a way that each LSP in the TCP/IP handler are chained together. If one of these LSPs is removed incorrectly, that chain could become broken, possibly removing your ability to connect to the Internet or a network.
Because you just want to fix a broken chain, click the Finish button, (designated by the green box in Figure 1. of the Tutorial).
LSP-Fix will automatically fix the LSP chain and hopefully restore connectivity back to the network.
Or you can try Winsock2Fix
, if that fix didn't work .http://www.bleepingcomputer.com/files/winsock2fix.php
When you run it, click on ReG-Backup button first to backup the registry, and then click on the Fix button.
