Dhcp failed to start

[perfectpol7]

On my server Linux Redhat Enterprise 5.0 i want to configure dhcp server but when i check the dhcp status the dhcpd was stopped and i try to invoked or to start it failed. Even when open the graphical mode service configuration, check the box and click start the output error message is dhcp failed. the error: Starting dhcpd:Failed.
How would i start the dhcpd service to run

There is probably an error somewhere in the configuration file. If you need help to find it post the contents here so we can check it. I think it will be located in /etc/dhcpd/ and will be called something like dhcpd.conf

Your /var/log/messages file has the message:

** You must add a global ddns-update-style statement to /etc/dhcpd.conf

But you say that you have showed us the output from dhcp.conf. Is this a typo or is this causing the error?

[perfectpol7]

that is the output of the dhcp.conf which is causing the error. The dhcp.conf on the above post, I have added the ddns-update-style otherwise not on the right position. I will try to change it to different position maybe might work.
