I'm trying to setup a dhcp server on ubuntu 12.04 server, but I keep getting this error and dhcp can't start:

Nov  4 18:24:45 localhost kernel: [ 1277.497785] init: isc-dhcp-server respawning too fast, stopped

I installed it with apt-get install dhcp3-server; when I run the

service isc-dhcp-server start                                                                                                                  

I get the following output in my log file(/var/log/syslog)

I thought I configured my dhcp properly??

Here is my /etc/dhcp/dhcpd.conf :

ddns-update-style ad-hoc;

subnet 10.0.0.0 netmask 255.255.255.0 {
        option routers 10.0.0.1;
        range 10.0.0.50 10.0.0.70;
        option subnet-mask 255.255.255.0;
        option broadcast-address 10.0.0.254;
        option domain-name-servers 10.0.0.1;

        option netbios-name-servers 10.0.0.1;
        option netbios-node-type 8; 
}
allow booting;
allow bootp;

        next-server 10.0.0.1;
        filename "/tftpboot/ploplinux-netboot/pxelinux.0";

        # You need an entry like this for every host
        # unless you're using dynamic addresses
