Then it should work if you can do this things:
1. Do a nslookup of a ip.
2. Ping the ip
then the ping domain name will work too, because it does just these steps.

Check the contents of /etc/resolv.conf and make sure that it specifies valid "nameserver"s. Also check /etc/nsswitch.conf to be sure that "hosts" includes at least "files dns".

here is an example of /etc/resolv.conf


[pablo@omega Mail]$ cat /etc/resolv.conf
search antel.com
nameserver 200.199.40.12


and is nsswitch,.conf you need to have this

#hosts:     db files nisplus nis dns
hosts:      files dns
