I recently upgraded a NetWare 6.5 server to Support Pack 6. I also applied
the post SP6 NDPS patches since we were seeing the issues outlined in the
TIDs. I'm currently running NDPSM.NLM 3.02 dated 11/30/2006 and NDPSGW.NLM
4.00.05 dated 11/16/2006. I have approximately 100 printers attached,
mostly Jet Directs and Dell (Lexmark) using LPR. We are seeing frequently
LPR communication failures with these printers now requiring a
shutdown/restart of the printer. It seems to happen mostly with the
standalone Jet Direct boxes that have dot matrix (Okidata) printers attached
to them. I tried switching one of hem to the RAW (9100) mode, but I am
still getting reports of the problem.

Has anyone else seen this? Any other ideas on how to work around it? I'm
starting to regret loading SP6! ugh!
