Can't see PC files after connecting NAS

Well, I kind of figured it should be possible, I mean, it’s only two seperate network connections after all.  But, I can’t make the WD see the PC.  When I open up Wondow shares, all I see is the TS412.  Very frustrating, I’ve tried to reset everything I could think of.  I need a hand here.
