Oplocks are really a bad idea, they say. With oplocks, Windows caches
the data locally to speed things up, but,if the network is bad and slow,
oplocks don't work either, because other clients can't access the data
because another client has that data cached locally. If the oplock
connection to the server is lost because of a bad network connection,
then data corruption is possible. (This is what I have heard said or
implied on this list.)
Try turning oplocks off.
