You should configure S4 to use the default root hints to ensure that network users can access Internet Web sites by using their FQDNs while ensuring that user access to internal resources is not disrupted.
Key Takeaway: Root hints are DNS data stored in a DNS server. A DNS server contains a list of preliminary resource records or root hints that can be used by the DNS service to locate other DNS servers that are authoritative for the root of the DNS domain namespace tree.
Root hints are used to prepare servers authoritative for non-root zones so that they can learn and discover authoritative servers that manage domains located at a higher level or in other subtrees of the DNS domain namespace.
These hints are essential for servers authoritative at lower levels of the namespace when locating and finding servers under these conditions. The root hints are stored in the file CACHE.DNS, located in the systemrootSystem32Dns folder.
