Pelo que encontrei:
The easiest solution I have found to
getting your files to show in the
Windows 7 Media Player library is a
trick I used before in Vista.
Start a command prompt as
administrator
In your C:\Users\XXX\Music directory,
use the mklink command to create a
directory symbolic link e.g.
C:\Users\Alan\Music>mklink /d Alan
\ANP-CUBE\music\Music\Alan symbolic
link created for Alan <<===>>
\ANP-CUBE\music\Music\Alan
After that I simply navigated through
the link in explorer to a music file
and chose Play.
Windows Media Player started up,
played the file and also started
populating the library with all my
music files
I have done the same with the Public
directory for files I share with my
wife:-
C:\Users\Public\Music>mklink /d Public
\ANP-CUBE\music\Music\Public symbolic
link created for Public <<===>>
\ANP-CUBE\music\Music\Public
Acho que a solução seria adicione seu NAS a um Grupo Doméstico .
De acordo com este post , ele deve funcionar, mas depois novamente é da própria Microsoft; -)
