Netware 6.0 sp4, latest CIFS patches, no file caching...

A UNC path to a CIFS volume doesn't refresh properly when files or
folders are created. You can create a file but it doesn't show up until
you manually refresh the windows.

A mapped drive to the same CIFS location does not exhibit this issue

I've tried to reproduce this issue with SuSE linux and Samba 3.0.x and
Windows 2000 & 2003 servers...they all work fine!

Any clues?
