We have recently encountered an issue where we have noticed that certain
PCs can not access recently added files to a particular file server. We
have determined that the rights are applied correctly to allow all users
in our environment to see the files. We have also logged in using the
accounts of the users who can not see the files on test machines and
confirmed the files can be seen. These users are physically at a
different location.

Has anyone seen anything like this before full well knowning the files do
exist the directory, and the users do have permissions to see them?

I can provide more specifics if needed, but I am fishing for general
places to look for potential problems (possibly configuration settings in
the Novell Client).
