I have the same problems all have described here regarding using the DNS iTunes server feature. So I went a different route and tried connecting it as a share drive. If I go to files and add to library from any music files on the DNS. I am welcomed with the spinning beach ball of death every time. After a while it eventually finishes locating the file and it plays the song. then if I quit iTunes and reload again to play the file, it does the same thing all over again. But just yesterday I tried ejecting the DNS323 drive from shared drive on my Mac first, then started iTunes, selected a song file from music library and no spinning beach ball of death, everything works fine. iTunes is working fine recognizing the DNS323 as a share drive without any loading problems only if I have the drive disconnected from shared, then starting up iTunes. Has anyone else gotten this?
