Thank you, Patrick.  I tried all the steps you were kind enough to list.  To
resolve I changed the two HPs with the NAT addresses back to their old IPs,
rebooted network services, and DSLINE and DSCOPY worked!

HP thought it was odd, but it works!

Thank you everybody.

Sorry to get in so late on this thread (and that's why I didn't post it to
the list), but I wanted to clarify something.

Try (in this order, but you may not need to do both):

1) :NETCONTROL UPDATE=NETDIR;NET=<niname>  {whatever your LAN card is named}
   This will load the new addresses into the NS Directory

2) :nettool.net.sys
   [1]>>>nameaddr
   [2]NAMEADDR>>>mappings
   [3]NAMEADDR.MAPPINGS>>>mapping
This will give you a list of all IP addresses mapped to the corresponding
machine addresses. Then if you do:

   [4]NAMEADDR.MAPPINGS>>>delmapping
it will prompt for the IP address you want to delete, and clear it and its
mac address from memory. This will force the system to go back and look up
the updated IP address in NSDIR. I have had to do this numerous times when a
printer gets moved and is assigned a new IP address, but retains its name.

Please note that IP to mac address mapping only applies to your local
subnet, so just about any address Bob sees in his situation (like your 939
and 997) is likely an "old" one and should probably be deleted. The beauty
of it is, even if you delete one you "shouldn't," no harm will be done
AFAIK, since the next packet to come from a particular mac address will
cause the entry to be repopulated.
