I have ran into something I find strange and I can't figure out what can
be the cause.

Users experience from time to time that when the look into a netware
drive (most often via ftp, but also when they are logged into the
system) that they can see the directories but only a few files. The next
day the have no problems and can see all files, then two days later 90%
is invisble again.

Can anybody give a clue about what is ging on?
