Winsock Settings Repair/Reset (Windows XP SP2 Only)

An LSP is a type of software 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 deletion of the software, this chain can get broken, rendering the user unable to access the Internet.

Unfortunately, this type of software is sometimes quietly installed by unrelated software such as file‐sharing programs sneaking into a system unannounced.

In fact, in many cases, the user does not know of its existence until something goes wrong, and they can no longer access Web sites. ( Frustrating )

Common offenders include New.net, and WebHancer, which are often bundled with file‐sharing utilities, DVD player software, and other free downloads.

The command detailed below repairs the Winsock LSP 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.

Winsock now has the ability to self‐heal after a user uninstalls such an LSP.

This new command is available in Windows XP Service Pack 2.

netsh winsock reset catalog

This command resets the Winsock catalogue to the default configuration.

This can be useful if a malformed LSP is installed that results in loss of network connectivity.

While use of this command can restore network connectivity, it should be used with care because any previously installed LSPs will need to be re‐installed.
