Add "deny known-hosts;" to the pool like this :

shared-nerwork Desktops {
   subnet netmask {
     pool {
       deny known-clients;
   subnet160.1.2.0 netmask {

host { hardware ethernet 00:11:22:33:44:55; fixed-address }
host { hardware ethernet 00:11:22:33:44:5a; fixed-address }
host { hardware ethernet 00:11:22:33:44:5b; fixed-address }
host { hardware ethernet 00:11:22:33:44:5c; fixed-address }
