To resolve a network Path from a Mapped resource use the following:
WNetGetUniversalName()
And look at the MSDN section "Windows Networking (WNet) Overview" topic.
Related items would be:
WNetGetResourceInformation()
WNetGetResourceParent()
etc.
Header: Declared in Winnetwk.h.
Library: Use Mpr.lib.
Hopefully this will help
