My resolv.conf looks like this, where search NAME points to the 
nameserver IP:

nameserver #.#.#.#

I double-checked my settings... Your box uses "domain" whereas mine has 
"search". I don't think that makes a difference. When using the full 
hostname I still cannot ping the DNS server from Linux.  I can ping 
using Win XP using both hostname and ip.
