Hi All,

i have DNS configured on my centos 5.2 server.

it's all working fine, right now i want to change the main public dns 
from one IP to another to do some testing (the new public dns ip has 
records which the old one doesnt have and it's done as such for testing)

so i got into /etc/resolv.conf and changed the first nameserver to the 
NEW public DNS.
/etc/init.d/network restart
/etc/init.d/named restart

when i issue an nslookup example.com ON the dns server, i get the exact 
IP i want to do testing on.
but when i do nslookup example.com on the clients machine. the website 
resolves to another IP ( the one set in the initial public dns records)


is there any other changes i need to do for the DNS server redirects its 
requests to the new public dns ?
