The effect which Tracy mentioned (single network user is faster than

accomodate
datastreams as well as OppLocks. The common solution is to disable
that
caching, which effectively kills the OpLocks problem. For that you have
to
set three Registry Keys at the CLIENT, nothing to do at server side.
You
can/should check for correct settings in your app at startup, but you
(normally) can't change those settings on the fly, since you need Admin
Rights for that. (Thus you'd better package those into your installer)

Hi wOOdy,
See here: https://www.screencast.com/t/4tEaNq72
I don't see those 3 different settings (DirectoryCacheLifetime,
FileNotFoundCacheLifetime, and FileInfoCacheLifetime) at all. Plus, the
middle column in the M$ page--those values all look the same:

I'm confused?
