Kevin,
If you have the full version of VS there is a utility called Depends.Exe. You can use it to open the DLL and determine what files are needed to support that DLL. With the version I have (4.0.1381.201), other than the core OS files, it seems WSOCK32.DLL needs WS2_32.DLL and WS2HELP.DLL. I don't know how deep the connection goes but you might want to take note.

Good luck!
