[Networker] ndmp errors

Hi,
I have been struggling with this ndmp error for over a month. I have a
netapp filer connected via
fiber to my spectralogic library 64000 (4 sony drives), and my networker
7.1.3 windows based 
server drives this. I also have scsi drives connect which are working
fine. I have replaced:
fiber cable, fiber nic card, tapes, library firmware, and nw upgrade.
still I get this message and the backup fails.
does anyone have any ideas? 
I get this on digest, so email direct if you have an idea, I am out of
ideas. thanks in advance,
sharon sampson
