I would try browsing to the network location rather than inserting it. If it shows up in "my computer" then you should be able to browse to it. If it doesn't show up in "my computer" you need to figure out how to get it there. Perhaps you need to give it an alias which makes it look like any other drive?
Once iTunes sees it it still won't play the files until you add them. Naming a music folder in iTunes advanced preferences only tells it where to put files it adds in the future, not where they are now. To add them you can either use the iTunes menus or just drag and drop the file folders into the iTunes library.
