Network drive connected to router

[dhsmith77]

I've added a big standalone drive to my network, connected to my Linksys router and made it the repository for my music and media library. ITunes is happy with that drive but subsonic seems unable to recognize it... the address of the drive looks like this

\\LINKSYS01859\My Book\FreeAgent Drive\My Documents\My Music\iTunes\Music

What do I have to do to get subsonic to recognize this source... when I add it to the media folder list I get a "folder not found" error message.

Thanks
