Two things to look for:
1. Is a copy of dhcpd already running and bound to the port? ISC dhcpd
doesn't automatically know how to disable other copies of itself, nor does
it currently know how to restart itself. Check for other copies of dhcpd
and kill them before starting up another copy.
2. If you are dynamically assigning addresses, you may need a range
statement in your dhcpd.conf. (This shouldn't be a problem for the
difficulty you're seeing, though.)
(Special bonus!)
3. There is a 1.0 release of ISC dhcpd which fixes some minor bugs.
