I am not sure if this is the correct forum, but here goes.

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.

Thanks in advance
