Thanks for the tip Jakesnake... I have always had the same problem when moving/deleting/renaming files in Windows 2003 server. Sometimes it would work, other times it refused and I had to close all explorer windows and do what I wanted from the command line. Deleting that registry key fixed everything.

Note: Deleting the key has the side effect that windows will no longer retrieve metadata for media files. This means things like duration, length, artist, etc will not show up in the "detailed view" or in property pages.
