The WNetAddConnection2 function under pywin32 seems to work. I am able
to make connections to various SMB network resources hosted by
Windows, Mac, and Linux boxes. It has the annoying side effect of
opening a connection.

There is a Win32 function called NetShareCheck. It sounds perfect. It
just checks that the share exists (no connection left open) and does
not require username or password. Unfortunately it fails for Mac and
Linux SMB resources. Just FYI.

I understand Samba and Windows SMB are not the same thing. What I was
hoping for when I investigated pySamba was to find a python module/
extension that supported a simple SMB interface and would run from any
host platform.
