Novell queues and VMWare...

I've built both Netware 6 and 6.5 servers in VMWare and retired two standalone servers.  These are using NDS queues.  Printing now is erratic; works for awhile and stops.  However the server console shows the print server is still attached.  I reboot the printer and it starts working again.  Anyone know anything in VMWare that could be related?  Always worked fine with two standalone servers; nothing else has changed.

The only thing I can think of is the fact that with VMWare's hardware virtualization, NetWare doesn't "know" that it is virtualized. The result tends to be discrepancies between the hardware clock and the OS timekeeping.

eDirectory, on which NetWare v6.X relies for authentication and access control, is *very* sensitive to time slippage like can result in a VMWare environment.

The fact the everything worked fine in a non-VMWare environment really does suggest that this function is not one that does well with hardware virtualization. Have you considered a para-virtualized solution like Xen? NetWare VX is essentially NetWare virtualized using Xen.

Problem was resolved and not related to VMWare.  When the new servers were built the print object names were changed to nine or ten character names.  A network trace showed them being intermittently truncated.  When I shortened them to six character names everything appears to be fine.  As for the second solution, I have seen time sync issues as described here but that is not related to this problem.
