Does all your workstations use the Novell client 4.83 sp3?
I know there have been issues with specific Novell clients. We use 4.83 sp2 and 4.90.0.0 SP1a without any problems.
Another possibility is that this station has something different in the Novell search paths and it is finding one of these files in some other directory. Adagio data files should never be found through a Novell (or DOS) search path.
