[Samba] Rename problem with Explorer & Mediaplayer

[root]

	There seems to be a problem with Samba and Explorer.  With some 
files Explorer opens up a associated viewer app (e.g. Mediaplayer) inside 
the Explorer window.  This prevents the user from renaming the file.  
Samba complains about a sharing violation.  Renaming a media file that is 
served up via a Windows 2000 server does not generate this error.
	Any ideas on how I can get around this problem?
