I have recently installed a NetWare 6.5 sp5 cluster. This is being used as
a file server for over 6000 users. The majority of users are not having
any problems, but some users (not always the same ones) are losing the
mappings to the server. They are getting the messgae "Invalid file
handle". We are currently using client 4.83 sp 2. The only fix is a reboot
of the workstation, a logon refresh does not remap the drive.

Has anyone got any ideas why these clients rae losing mappings, I also
have mappings to 5.1 servers on the workstations at the same time and
these do not drop.

I know an upgrade to the client will be suggested but can anyone confirm
that our current client is the cause of the problem, before I start an
upgrade of 3,500 workstations

Thanks in advance
