Using Itunes in a network

Im having a problem with Itunes which may effect whether I can use it or not, Id really like to so if anyone is able to help out with the following Id appreciate it.

I have a Windows server with a 200gb partition of MP3 files (I backed up my cd collection) which I want Itunes to use. I dont want to import anything to my Mac (impractical, not enough space),and want Itunes to look to my network share for the music it plays as its default directory.

I have pointed the ITunes music folder location to my Network share, but nothing appears in the Library, and assuming I can get them to, I guess Id lose everything when the share drops off when I put the Mac into sleep mode.

Thanks for the reply, sorry, I just reedited my post before I saw your reply.

So from what you say I would need to manually drag things from my network share into Itunes each time something is copied there? I was hoping it would simply display whatever is in that location. Also, I have a structure of -

Artist/Albums/Album Name/*.mp3

and

Artist/Tracks/Track Name/*.mp3

Im thinking that ITunes might want everything in the one directory, is that likely?
