LSP Fix is a utility which can repair a specific type of problem associated with certain Internet software. This type of software is known as a Layered Service Provider or LSP, a piece of software that can be inserted into the Windows TCP/IP handler like a link in a chain; however, due to bugs in the LSP software or accidental deletion of the software, this chain can get broken, rendering the user unable to access the Internet. LSP-Fix repairs the chain by removing the entries left behind when LSP software is removed by hand (or when errors in the software itself break the LSP chain), and removing any gaps in the chain.
