hey bassam, you didn't fix this problem yet ?
that's what we gain from admins testing the network nodes and saying that they are not working just because the laptop they are testing with is closed :P
alaa: yes, they are running bind.

Your question is not clear. Is the machines has only your local DNS server only ? i.e in Fedora:

cat /etc/resolv.conf

You should see "nameserver x.x.x.x". What is there, is it your local DNS ? if not make it pointing to the local DNS. If yes and still your DNS server is the one always go outside to resolve, you misconfigured your DNS then.

You need to configure BIND so it is master to your local domain, and you need to run DNS Caching to enhance performance of DNS.

I would say it is your DNS Server configuration.
