Authoritative nameservers are like the phone book company that publishes multiple phone books , one per region. Recursive DNS servers are like someone who uses a phone book to look up the number to contact a person or company. Humans access information online through domain names, like nytimes.

Web browsers interact through Internet Protocol IP addresses. Iterative queries are also called non-recursive queries. A non-recursive query is a query in which the DNS Resolver already knows the answer. It either immediately returns a DNS record because it already stores it in local cache, or queries a DNS Name Server which is authoritative for the record, meaning it definitely holds the correct IP for that hostname.

An example might be if you are using conditional forwarding to resolve queries against a business partner's internal zone, and if a query fails, you would not want DNS to continue the process of name resolution. Microsoft simplified the wording starting on Windows consoles. If you do not want to use the root hints if the forwarders are not available, you have to uncheck this setting.

It will not query any additional servers if the DNS server is unable to resolve the query. To continue this discussion, please ask a new question.
