On our Windows 2003 DNS server, we have the two DNS server addresses of our
ISP in the Forwarders box. Is this the recommended configuration or should
I add other forwarders...such as google's public dns address?

Thanks!

Best practice is to use your ISP's DNS servers or use root hints.
Putting google's public DNS address in as a forwarder will not work because
google's public DNS address points to a website not a DNS server.

Two is enough, actually. Based on the client resolver service query TTL (time out), it may never reach the third. And I agree with Danny. Google's DNS addresses are useless.
