Locate lots of iTunes track file locations

Recent switch to new computer orphaned several hundred MP3 files. Moves were between network and local drives. And some were from one media directory to another on the same drive.

Ran turingtest2’s excellent findtracks.vbs script and grabbed a bunch of them. But a few hundred are not being recognized by the script. Even when I point it at the directories where the files are located, the script can’t find them.

I checked the directory permissions, confirmed none are blocked, and no media files or directories are read-only. I am the administrator on this machine, locally and on my local domain, so permissions should not be a problem. Not sure where to go from here, since I can’t sync my library without wiping a lot of media from my devices.

Would anyone have any thoughts on how to find the source of this problem?
