One of  the peer  servers for this  list seems to  be trashing  the ACK/NOACK
option fields.  I am  aware of  the problem  and will  investigate it  when the
installation of  our new  system is complete.  The 4381 is  up and  running and
I've  just finished  reconfiguring  the  UCW, but  the  3720  will arrive  only
tomorrow.
