    hi,
    I am trying to configure DNS (BIND 9) for my local lan only. I want it for my apache/squirrelmail access from local lan pc's (dont have real IP ).My apache and postfix with squirrelmail running successfully.My problem is that i can not access my web server from other pc's in my lan by htt://host.localdomain but can access it by http://ipaddress_server.
    I have gone through many configurations but failed to get it running.pls help.
    Thanks

    which dns-server is set on the clients you try to access / lookup host.localdomain?
    What is the output of
    nslookup host.localdomain
    from such client?

    What happens if you run
    nslookup host.localdomain
    or
    dig host.localdomain
    (depending on Windows / Linux) as OS
    on the DNS-Server machine? Does this result in a lookup for the correct IP?

    i am having 3 PC's named as Boss (192.168.2.3), Home (192.168.2.4) , star (192.168.2.5) and my Mandrake 10.1 is acting as Web , Mail server (postfix,squirrelmail) i am able to see my index page/squirrelmail login page by IP address only (from boss,home,star), and from mandrake itself its fine i can see it by http://serv.lin.ald

    I am trying to configure DNS for the purpose so that i can access my web/mail by giving http://serv.lin.ald from boss,home and star.

    The message means, that the DNS-Server that is expected to run on 192.168.2.2 is not answering.
    So at first you have to check on that machine why this is working / or not.

    For a general Information look at this howto: http://www.howtoforge.com/traditional_dns_howto
    or check other howtos in the DNS-category

    Did you configure your zones on 192.168.2.2?
    Did you add your internal nameserver (192.168.2.2?) to /etc/resolv.conf (as the first nameserver entry) on the clients?
