Does running "dhclient ed1" from the command line work?
Is the DHCP server providing the right answer?
Running "tcpdump -s 0 arp or port bootps" would give you insight into what the
network is seeing, at least. Doing this from your DHCP server or a laptop on
a hub with the interface in question would be useful vantages, or a "trunk" or
"span" port on a smart switch, depending on what you might have handy.
