I looked through the 3 pages of post and did not see anyone else with the same issue or any solution to my issue. My goal is to use the Itunes "service" on all systems on my network. Please respond after you read my whole post please. With that said I am open to any suggestions but would appreciate responses to my post actually on my issue.

Thanks for the read.
My issue/ Findings:
QNap TS-419P+ 4 drives installed Version 3.4.1 Build0315
Itunes service is on
Mac Desktop see's QNAPSERVER(itunes) and works perfect.
Mac Laptop see's QNAPSERVER(itunes) and works perfect.
Windows 7 x64 ultimate Laptop see's QNAPSERVER(itunes) shared service but once I click the share, the itunes client starts acting like it is scanning and then drops back to the default music folder.
Windows 7 x64 ultimate Desktop see's QNAPSERVER(itunes) shared service but once I click the share, the itunes client starts acting like it is scanning and then drops back to the default music folder.
Mac systems work fine, PC/s does not. I have reinstalled my desktop becasue of a recent raid issue and with nothing loaded but the OS/patches and Itunes I have the same issue. Things seem to point to some kind of incompatibility with the itunes service on the Qnap server and PC itunes client.
Can anyone validate that the Itunes service works on with the qnap server and their Windows 7 PC? I'd also be interested what model QNAP server you have as it could also be a model version issue.
Thanks again,
-Greg
I'd also like to add, I am using Round Robin for the network configuration on the Qnap Server with a Linksys 52 port switch. Nothing special is configured inside the switch. I don't feel its an issue there as the Mac systems work. But thought the Round robin configuration could have some bearing on the situation. Thanks again.
*Update*
Looks like I'm not the one one with this issue Link to the German QNAP site (Its a cached version and translated to English):

Well I was able to work though some of the issues, but Itunes service still does not work. FYI I resolved the itunes service not liking certain music files by just moving the files off the server and then back to the server again (I know nice right)... As described in the links above I was getting errors like the ones in both links above when executing the commands in the second link. Since deleting my music is not an option as he chose to do. I moved what ever it did not like off and ran it again until it completed. I deiced to put the music back and see what would happen if I ran it again. Worked fine... however the Itunes service still would not work with the PC...
*3rd Update* - Resolved
I had to format every drive and reinstall the firmware. Itunes is working from everything now. I am doing the file transfer from the ssh console in the hopes that this will correct whatever is making the system not happy... I have an external dual dock eSATA bay. I have a 250GB with my music on it formatted in NTFS from when I made a backup. I'm performing a copy command:
Copy Recursively(sub folders/files) /Source path/ /Destination path/
cp -r /share/eSATADisk1/Music /share/Multimedia/Music
Don't forget to change the owner and group if needed:
chown -R Username /share/Multimedia/Music
I reset the system, removed all the drives, formatted them in the NAS reapplied the firmware. Reapplied the old firmware. All same issue. During my quest I loaded a QPKG ( and my apache folder was made into a file base on what I saw in the SSH client, being new to Linux I could not figure out the command to make it a folder again. I worked a 'fix" that did not get everything back the way it was originally) to see if that would be a good alternative and it corrupted my web service and Itunes stopped working all together. I found a comment that someone formated the drives from another PC rather than the NAS. I figured that's the only thing I have not done yet and like new again. So far... everything is working on PC and Mac with Itunes.
I Hope this helps someone else... Apparently if you have an issue there is no real solution based on all the forums I have sifted though for the last week. Backup and format the f-er seems to be the path of least headache/ heartburn. I'd love to see some type of good logging so I could look at it to tell me what the ** is really wrong...
