Hi,

    Hi ,

    Configure forwarders or root hints for external name resolution in an Internet-connected environment.

    Root hints are present by default on Windows servers, but forwarders must be configured manually. DNS Server will contact Root Hints only when it no Forwarders available or when Forwarders cannot resolve the query.

    As Dave posted, you can set ISP or pubic DNS as forwarders. E.g. Google Public DNS: 8.8.8.8 and 8.8.4.4.

    For difference between DNS forwarder and root hints, you can refer to the following article. This can help you understand better:
