DNS on LAN

Hi all.
I am trying to use BIND9 as DNS server. All goes well, except that i can't lookup my relative LAN hostnames instead of full domain names.
F.e. i can lookup
host hostname.subdomain.domain
but can't
host hostname

This is my master zone file
---------------------
$TTL 3h
stub.saburovo.com. IN SOA solaravm.stub.saburovo.com. root.localhost. (
5
3h
1h
1w
1h )

stub.saburovo.com. IN NS solaravm.stub.saburovo.com.

localhost IN A 127.0.0.1
solaravm IN A 192.168.1.4
rhelvm IN A 192.168.1.5
bsdvm IN A 192.168.1.6
-------------------

so
host solaravm.stub.saburovo.com
work well
but
host solaravm
didn't

if i add CNAME statement like that
solaravm IN CNAME soalaravm.stub.saburovo.com.

i have error
zone stub.saburovo.com/IN: loading master file db.stub.saburovo.com: CNAME and other data

This is a client configuration thing. Set up the clients to supply the default domain name on unqualified queries. In /etc/resolv.conf the search directive specifies the default domain(s) to search in. In Windoze, it's a box in the same tab where you specify whether to use DHCP or static IP addresses somewhere in the network settings. (Sorry, don't have a Windoze box. Actually not sorry at all.)

Yea. I added domain to resolv.conf with this line
domain stub.saburovo.com

and all goes well

Thanks, era.
