It is likely that you already have dhcpd running:

ps -lef | grep dhcpd
/usr/sbin/lsof -p <pid_of_dhcpd>

The reference you see in /etc/services is outdated/misleading.

Read "man dhcpd.conf" and go with the flow.  The NCD entries even look correct,
according to my memories of setting up NCDs about six years ago...  I think the NCDs
will default to loading their kernel from the BOOTP/DHCPD machine, so you will
probably need to enable tftp or NFS services from the same machine.
