I have to run a dhcp server on CentOS release 5.5 (Final).
# yum list| grep -i dhcp dhcp.x86_64 12:3.0.5-23.el5 installed dhcp-devel.x86_64 12:3.0.5-23.el5 installed dhcpv6-client.x86_64 1.0.10-18.el5 installed
after starting the dhcpd daemon, the windows Clients on the subnet (192.168.100.0/24) tells me, that there is no dhcp server available.
# /etc/init.d/dhcpd configtest Syntax: OK

How about firewalling ... does your firewall allow for a DHCP server?
