Bzzttt!! Wrong.

If you try to read the directory of a network drive with a broken connection
you will (By default) get the infamous abort/retry/ignore message. Not very
helpful for letting you know.

A better way would be for a small program to 'ping' the netware server using
the netware diagnostics, and then alert you if it can't. The good thing about
this is that its easy., low overhead, and you can do it without the netware
shells, and just with the packet drivers (or similar) loaded. You could even do
it from a Unix workstation through the networkinterface. (A netware diagnostics
broadcast will elicit a response from all netware aware machines, and can be
used to map the network, and find which machines are up or down (Including even
what OS they are running).
