You guys sound like you're having problems similar to mine. I've got a LS-XHL, not a LS-WXL, but I'm going to assume the nuts and bolts are similar.
I've set up my media server, and it (eventually) successfully sees all 67,000+ music files, they play well in iTunes (I'm using a Mac), and everything's right with the world. Then I turn off the NAS (I cycle it off at night to conserve its life), back on the next day, and poof - no NAS media server share shown in iTunes. I try getting the OS to load the music share separately (through Finder), I try restarting the media server, then opening the modify dialogue to make sure everything is still set correctly, then making it refresh - all no go. The NAS share never comes back up in iTunes.
This isn't a NAS media server share comes up, but comes up empty problem - I fixed that by updating to iTunes 10.0.1. This is a no share appears at all problem.
The only way I've found around this is to reset the NAS back to factory defaults, then reprogram the media server. Of course, this means reprogramming all my user folders, permissions, etc, etc, and is a serious pain. Oh - and I can't ever turn the NAS off again, lest I do all this over again.
Does this have to do with the current firmware (1.34), or am I doing something wrong?
Thanks!
