LinuxQuestions.org - Major problems with DHCP

I've been reading many guide on setting up a DHCP server, and i'm still having problems.

I installed Webmin, and i'm setting up my DHCP with that.

I've tried to start the DHCP service, but I get an error message.....

Failed to start dhcpd :

Starting dhcpd: Internet Software Consortium DHCP Server V3.0pl1

For info, please visit http://www.isc.org/products/DHCP

** You must add a ddns-update-style statement to /etc/dhcpd.conf.
To get the same behaviour as in 3.0b2pl11 and previous
versions, add a line that says "ddns-update-style ad-hoc;"
Please read the dhcpd.conf manual page for more information. **

If you did not get this software from ftp.isc.org, please
get the latest from ftp.isc.org and install that before
requesting help.

I've added the line "ddns-update-style ad-hoc;" to my dhcpd.conf file, and saved it.
But it still gives me the error. I have also downloaded the new dhcp from their website (which i don't know if I installed right), but it tells me I have the lastest version.

Any idea's???
