In the past months I had similar locking problems: outlook running on a 
client PC, outlook.pst file stored on a (private) network share. The 
client PC would sometimes hang, and the user would then reboot the PC.
After the reboot, Outlook complained that the outlook.pst file could not 
be opened because it was already locked by someone else (in fact it was 
the "old" smbd process of that same user that didn't notice the client 
did reboot).
The solution was always to manually kill (-TERM) the "hanging" smbd process.
The situation got a bit better when I disabled oplocks entirely, but I 
still get that error sometimes (yes, we *almost* fixed the PC hardware 
issues :-).

Thanks to your post, I'm considering putting this configuration option 
in place.

Did you have some PC-freeze problems that the "reset on zero vc" config 
parameter solved ?

Did the use of this parameter have some drawbacks ?

Thank you.
