DNS not resolving

I have 2 DCs in our environment, Win 2008 R2, both of them DNS servers, all of the work stations point to them for DNS. I have tried to brows to a website from one of the desktops but was not able to, was not even able to ping it by name. I have connected to the DNS server and was able to get to the website and ping it, I have copied the IP of the site and was able to get to the site on the desktop using the IP address. What could be the problem, why is the name is not resolving even though all desktops are pointing to correct DNS servers?

Thank you,

Sergey

Does this experience happen on all desktops? Have you tried to do ipconfig /flushdns? Do you have a firewall (dmz) that is blocking your DNS traffic from your desktops and an exception for your DC's? Make sure that your forwarders and root hints are set correctly

Thank you for all of your responses, I have cleared cache on both DNS servers, then ran ipconfig /flushdns on desktops and that solved the problem.
