External DNS Record Management

Our external DNS record is currently being managed by our ISP. We are going through the process of moving this management to a hosted service.

I obtained a copy of our DNS records and recreated them on the new service.

I also added the new nameservers to the service that we have registered our domain name with.

I logged into our master domain controller and launched DNS Manager, opened the properties of the DNS Server object. Under the Forwarders tab I added the two new nameservers, however, under "Validated", I see "An unknown error occurred". Can anyone tell me how to remedy this error? Is there another configuration change I need to make to our master domain controller?

We have Cisco switching, routers, wireless controllers, and our DMZ is a Cisco ASA5510. Will we need to configure these new nameservers on any of this equipment?

THANKS!

Thanks for the explanations - it helps to understand how this all comes together, but what if the forwarders that are currently configured will no longer be available? It was a backup ISP service that we will soon be disconnecting. Do we add the nameservers of our current ISP to the forwarders list? I really appreciate the quick responses!

Yes, the best forwarders to use are the most reliable DNS servers that are available and near to you (by latency), so your ISP should be the best option for you.
