	   the booting sun sends out a tftp broadcast packet, trying to 
    find its server.  instead, the ti sends it something that makes it
    quite ill.

I would argue that Sun is in error in sending a TFTP packet as a
broadcast.  If you don't boot over the network, beat on Sun to provide a
boot sequence that doesn't do the broadcast.
    
					    (... udp appears related to 
    tftp).

TFTP is an application protocol running on UDP (similarly, FTP runs over
TCP).  TCP and UDP are transport protocols running over IP.
    
    any ideas?

(IP:RESET-TFTP-SERVICE NIL) will shut off TFTP service and prevent the
Explorer from responding to the Suns' TFTP requests (or anybody else's).
(IP:RESET-TFTP-SERVICE T) will start it up again (as will (NET:RESET T)
and (IP:RESET T), which call it).  You could put the form in the
boot-init file for the machines if you want to shut it off more-or-less
permanently.
