Windows XP Service Pack 2 - New Winsock NETSH commands

Two new Netsh commands are available in Windows XP Service Pack 2.

netsh winsock reset catalog

This command resets the Winsock catalog 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.

netsh winsock show catalog

This command displays the list of Winsock LSPs that are installed on the computer.

To output the results to a file type this in Command Prompt (CMD.EXE)

netsh winsock show catalog >C:\lsp.txt
