All of our *.dxf files dated 2004 or older are gone from a particular
directory and I am trying to determine if a user deleted them or if
there is something wrong with NSS??

The server is fairly new <2yrs old PowerEdge with Raid-5, NW6.0SP5 and
post NSS patch. I have DSmeter monitoring the main directory, but I
didn't have it set up on this one. I will look in tapes, but I rotate
on a 5 week basis, so if they have been gone for a long time I won't
have them.
I will also look on retired tapes, but they aren't too reliable

any ideas/
