I've got a Mac Pro running Mac OS X 10.6.4 Snow Leopard Server and it's recently started getting numerous 'kNetworkError's in Server Admin.app when viewing services. It's acting as a gateway w/NAT and has been so for quite some time.

There is one glaring issue, bootpd crashes all the time with the following errors in `/var/log/system.log/:

It is correctly configured to serve DHCP through en1 (not en0), the "LAN" port. This happens even with no hardware (even switches) connected to the "LAN" port. There are no DHCP clients listed. Oddly, the "Overview" shows 1 static map, but nothing is listed under "Static Maps" and there are no "Computers" in Open Directory. /var/db/dhcp_leases is empty.
