Help: "Unable to play...access to //NAS denied"

[superuser]

I just had all my CDs ripped to a NAS. I can access my NAS from my main PC (WinXP laptop) and Sonos has indexed the music on the NAS. However, I can't seem to play the songs on Sonos b/c of the error msg: "Unable to play [song name]...access to //NAS/[folder name] denied" (my NAS is called "NAS" and the names in brackets are illustrative).

Any thoughts?

Is the NAS share password protected ?

Can you set a password for this share ? If so :

1 Reboot the NAS
2 Setup a password (e.g.SonosShare)
3 Delete the reference to the existing share in the Sonos Desktop Controller
4 Restart Sonos Desktop Controller and input the share again - this time with the password (e.g. SonosShare)
5. Wait till the re-index has been done
