Windows: AFS Redirector Network Provider

Browse Source 
In Windows a network file system must have a matching network
provider dll that interfaces with the Multiple Provider Router
(MPR) to support the WNet APIs called by the Windows Explorer
Shell and other applications.  The WNet APIs are primarily
used to support driver letter mapping but they also have a
number of other functions including universal name mapping,
path formatting, and path parsing.

Jeffrey Altman <jaltman@your-file-system.com> contributed to
the development of the AFSRDFSProvider.dll interface.
