Hi,

   Check the following 2 files:
/etc/resolv.conf   ---> need to have "nameserver <Your DNS IP>"
/etc/nsswitch.conf  --> need to have "hosts: files dns"

   If you still have problem, then please post your error messages of nslookup and the output of "ifconfog -a", "netstat -rn", as well as the content of
/etc/resolv.conf.

Do you mean the linux box (206.101.188.5) itself is a DNS server?
If yes, then you need to config Bind and run the named on it in order to make DNS server up and running first.

However, in the /etc/resolv.conf, it shows you use other DNS server, 204.70.127.127 and 204.70.127.128.

Did you check
/etc/nsswitch.conf  --> need to have "hosts: files dns"

and can you ping  204.70.127.127 ?

Please make your question clear: DNS client to query DNS or setup a DNS server.

DNS Server, it ran great for thgree years and blew up yesterday.  (206.101.188.5) is the DNS server.  Resolv.conf is point to the upstream resolving servers for domains not controlled by us.

Nsswitch.conf -> hosts: files dns

Can ping resolvers

Thanks

DNS is different issue.
Please check whether there is a process "named" running or not.
If not, then use "/etc/rc.d/init.d/named restart" to start it.
If you have problem to restart the named, then please post the error messages from /var/log/messages.
Also, please provide /etc/hosts content and roll-back the change you made recently.

You are welcome.
I think there may be something wrong on /etc/hosts, /etc/named.conf and some files under /var/named.
Those are DNS server related files.

Good luck,

Wesly
