Microsoft is giving their Winsock LSP sample back from 1995 when Winsock LSP was first used with Windows 95, up until 2005 or so the quality of their default sample was lacking and much work needed to be done to make it work without any issues.

At our web site you can download Winsock sample lsp which is basically a repacked MS sample, we took the XP sample and put it inside a VS6 project which makes it easier to learn Winsock LSP, but we didn’t include all the modifications for our LSP which is so far ahead from the default sample in terms of features.
