Yeah, there's been plenty of these network appliances that really foul up their implementation of permissions. MVFS and NetApp are a couple in the past that have had problems. If you have the csih package installed, run /usr/lib/csih/getVolInfo drive letter:/ and send the results here. And then wait for the groans. ;-) -- Larry Hall http://www.rfk.com RFK Partners, Inc.
