Richard,

I don't have time to go through that config line by line but here is
mine that works. It is not perfect, has some unnecessary stuff in it,
the domain used is a private domain but like I said it works so it
must have at least as much as necessary to make it work.

------------------------------------------------------------------------------------

[bepstein@dellnikon ~]$ more /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;

subnet 192.168.65.0 netmask 255.255.255.128 {

# --- default gateway
	option routers			192.168.65.1;
	option subnet-mask		255.255.255.128;

	option nis-domain		"nrims";
	option domain-name		"nrims";
	option domain-name-servers	192.168.65.1,132.183.243.118,132.183.1.1
1;

	option time-offset		-18000;	# Eastern Standard Time
#	option ntp-servers		192.168.1.1;
#	option netbios-name-servers	192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
#	option netbios-node-type 2;

	default-lease-time 21600;
	max-lease-time 43200;
	range 192.168.65.50 192.168.65.125;

	# we want the nameserver to appear at a fixed address
	host ns {
		next-server marvin.redhat.com;
		hardware ethernet 12:34:56:78:AB:CD;
		fixed-address 207.175.42.254;
	}
}
[bepstein@dellnikon ~]$

Hope it helps.

Boris.
