Is there any protection mechanism for a spamming dhcpclient?

   I've had printers go nuts as well, driving the server CPU to 100%.
They are making requests faster than the server responds.  There are in
effect more requests than responses.  Adding something to try any tell a
misbehaving client to change its behaviour, when the behaviour is that
it appears not to be respecting what the server is supplying would have
little effect.

 

   The one thing I found effective with the printers in our org is to
terminate the packet stream for about 2 seconds.  It seems to reset the
printer.
