Can't download from ITunes

[slmiller243]

I just created the FreeNAS server. Everything went well. I moved my ITunes library to the server. I can create folders, files etc and play music with no problem. When I try to download something from ITunes, everything on the desktop freezes (older Windows XP desktop). I don't see any error messages and the only way I can recover is to reboot the desktop. My gut tells me this is some sort of security/file permission problem but I can't find what it is. Any help would be appreciated.
