dhcp e dns internos

boa tarde,

estou com um servidor rodando unix e as máquinas na rede não estão achando o
servidor pelo nome.

as pessoas tentam acessar nas estações digitando \\b180 (nome do servidor)
e da erro. não sei configurar um dns, só fiz alguns testes.
um problema eh que rodo um dhcp interno.
gostaria de saber como configurar certinho o meu arquivo named.conf abaixo.
vai também o meud dhcpd.conf.
OBS: o dhcp está rodando perfeitamente.

valeu.
