Unfortunately - I didn't know I had sent anything! I had a inadvertent
key sequence while typing, and closed the window, and ultimately had to
kill the mail program.  So what I sent was incomplete....

This sounds like the CLIENTS are caching the data, rather than the
server.

I would try an initial test of disapling OPLOCKS on the share in
question:

[sharename]
  oplocks = no

This may impact overall performance, but will at least tell you if
oplocks by the clients are the issue.  If you determine oplocks to be
the issue, you can disable them on specific files or filename patterns.

You don't say what application is involved here, or what OS the clients
are running. File locking options and share modes can also be a factor,
but in any case, it all depends on what type of application you are
using, and you have not provided that critical detail. Is this a
database application, using shared files? If so, what database is used?
Access? dBASE (.DBF files), etc....

You could try (globally or on the share):

  locking = yes
  strict locking = yes
  share modes = yes
  dos filetime resolution = yes


Good luck!
