If suspect if you restart your dhcp server on the LTSP server by hand:

	sudo /etc/init.d/dhcp3-server restart

and then look in /var/log/daemon.log, you'll see a warning message like this:

Nov  2 14:36:03 brooks dhcpd: No subnet declaration for eth1 (192.168.1.49).
Nov  2 14:36:03 brooks dhcpd: ** Ignoring requests on eth1.  If this is not what
Nov  2 14:36:03 brooks dhcpd:    you want, please write a subnet declaration
Nov  2 14:36:03 brooks dhcpd:    in your dhcpd.conf file for the network segment
Nov  2 14:36:03 brooks dhcpd:    to which interface eth1 is attached. **
