You can try to edit "/var/chroot-dhcps/var/state/dhcp/dhcpd.leases" and restart the DHCP server by "/var/mdw/scripts/dhcpd restart".
But I'm not sure if the dhcpd (we use ISC dhcpd) keeps the lease table in memory and writes it to disk after a restart, so maybe you have to replace "restart" by "stop", edit the file and "start" it again...
