My guess is that the other system you're talking to hasn't flushed it's arp 
cache.  When DECnet-ULTRIX starts up it changes the physical address of the
Ethernet Card to aa-00-04-00-XX-YY (where XX-YY is of the relation XX *
256 + YY
= a * 1024 + n (a.n)).  If the remote system doesn't flush it's arp cache,
it will recognize the system.  Since DECnet-ULTRIX is started before IP, you
should only experience this one (the first time DECnet-ULTRIX is installed).

If the remote system BSD-based, try doing a '/etc/arp -d yourname' on
the remote
system.  This will delete the arp entry from the arp cache.

Why not just the C partition?
