Re: DHCPD events - Linux or Win Problem ??

Excerpt from my dhcpd.conf file modified for your network. Should work apples.

ddns-update-style ad-hoc;
subnet 10.0.0.0 netmask 255.255.255.0 {
	# default gateway
	option routers 10.0.0.1;
	option subnet-mask 255.255.255.0;
	option netbios-name-servers 10.0.0.1;
	option domain-name "internal.foo.com.au";
	option domain-name-servers 10.0.0.1;
	option netbios-node-type 0x8;

	range dynamic-bootp 10.0.0.10 10.0.0.20;
	default-lease-time 14400;
	max-lease-time 14400;

	# Some computers require special addresses
	host mycomputer {
	hardware ethernet 00:0E:47:39:7A:F7;
	fixed-address 10.0.0.10;
	}
