hmm.. i thought you could do an index like that, but it seems you can't anymore, that's
too bad.
found this in the help menu:
"Mounted servers, CD-ROM discs, and read-only disks...do not appear in the Index
Volumes window." it goes on to say that you can index it "directly on the shared
volume", which i assume means only if it's a mac, and directly from it's console. you
can get the contextual menu to give you the option (hold down the "ctrl" and click on
the volume from the finder) to index, but it doesn't work. sorry about that.

i'd still check his system & make sure he's running 9.0.4. turn off samba if you
aren't using it, or at least turn it off for now, to eliminate it from the equation.
is the problem intermitant? i tried to do a sherlock search here (i did 2 @ the same
time from different machines) and found it slow, but it worked, and my users telnet,
ftp, samba, etc. do your users open files directly from the server, or do they use
local copies and update the server (or is there a version control software running)?
i'm wondering if a file could be getting locked or updated as you said. one of the
most insidious problems i've had to deal w/ is users trying to include fonts off the
server in adobe type manager rather than copying them to the local drive, resulting in
weird startup problems, but that's a whole 'nother issue...

other than that, all i can think of is to make sure nfs isn't somehow on. i know it
can lock files that are in use.

will keep looking into it.
