Problem with DHCP on 3.7

All

I've been experiencing a problem on my OBSD 3.7 machines since I move
from a cable to a DSL connection for my broadband access

My setup is this

DSL modem->Linksys router->Multiple machine

When I try and run dhclient on any OBSD interface, I receive th
following error

Bogus Host Name option 15: domain_not_set.invali
(domain_not_set.invalid

following tha

Invalid lease option - ignoring offe

I note on my Windows machines, an ipconfig reports
domain_not_set.invalid as well, but it apparently accepts the DHC
offer from the Linksys router

My question is
1) Can I change OBSD so it ignores the Bogus host name

Any insight will be greatly appreciated

Thank
