[Samba] Share violation

[Oscar A. Valdez]

Ocassionally (not always), some (not all) of my Win 9x clients get a 
share violation when trying to open a shared file. I also have many more
DOSEMU/Linux clients that never encounter this problem. The log snippet
is as follows:

Tips and suggestions will be much appreciated.
