Dear, I am facing the problem of DNS error when i am trying to browse the page. its happening randomly, sometimes i am able to get the page and sometimes i am not and i get the error of Page Cannot be Displayed and DNS error. The same site if i try few times then i am suucessfull.
The browsing was fine, i never had this issue before but these days when i am browsing i am getting frequently the DNS error problem.
Structure is as follows
On 2003 Server Side.
DNS is IP of the server itself
in DNS under forwarder i placed three IP addresses as follows
x.x.x.x ---- ISP1 DNS IP
y.y.y.y ---- Local IP of the Firewall (Which act as gateway to the clients and also the DNS server)
z.z.z.z ---- ISP2 DNS IP
On the client side
DNS is IP of Windows 2003 server
Gateway is Local IP of firewall
