We have two NetWare 6 SP5 networks w/2 separate trees. Up until recently
file copying to and from both networks has worked fine NOW.... Copying to
and from Tree2 to Tree1 works fine. Copying to Tree1 works fine. Copying
FROM Tree1 results in an error

"Cannot copy <filename>: The specified network name is no longer available.

We can copy TO and FROM both networks on the Microsoft Side. I have
enabled packet fragmentation and black hole detection. Any ideas?
