This is telling you that the machine doesn't know how to assign addresses for DHCP requests that come in on the dc0 interface. If that's correct (i.e., you want it to assign addresses on some other interface but not that one), then everything's fine so far. If it's not, then you need to modify your dhcpd.conf as it said. If everything is okay on that front, then you need to get some of the other machines (the ones to which this server should be assigning addresses) to ask for leases. How to do this depends on what OS they are running, but rebooting should do it in any case.
