Hi all,

this is my first post on this list, hope someone can help me.

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

this is my /etc/dhcpd.conf

# cat /etc/dhcpd.conf
authoritative;
ddns-update-style interim;
subnet 192.168.100.0 netmask 255.255.255.0 {
         option routers                  192.168.100.11;
         option subnet-mask              255.255.255.0;

         option domain-name              "<mydomain>.local";
         option domain-name-servers       192.168.100.2;

         option time-offset              -18000;     # Eastern Standard Time

	range 192.168.100.150 192.168.100.199;
}

what do I'm missing? or is there a config mismatch?

many thanks
Richard
