If I want all users not to see the default netdisk F: (SYS) and Z:(PUBLIC)
from
"my computer" of XP, what should I do ?

I found if I add login script of mapping netdisk Y: (mapping to share
folder) to certain user account from Novell client's red "N", F: & Z: will
automactically disappear.
Only Y: was left --- That is what I want, but seems not a good way....

But if I add login script of mapping netdisk Y: (mapping to share folder)
to user group from iManager, F: & Z: still be there, of course, Y: also show
between them.

how to get out of F: (SYS) and Z:(PUBLIC)
