dhcpd on Solaris 10

[Glenn Satchell]

Hi Jason

With multiple interfaces the server-identifier changes depending upon
the interface. I would remove the two server-identifier statements,
typically they are not required, and the dhcp server fills in a
suitable value anyway. The only time the server-identifier is used is
if you have a virtual IP address on an interface (bge0:1 for example)
and you want requests to come back to that interface. The rest looks
pretty standard.

You can try running dhcp only using 1 nic by specifying the nic name on
the commandline, eg:

 dhcpd bge0

Might be worth trying to see if that makes any difference.
