For more information, see Deployment and operation of Active Directory domains that are configured by using single-label DNS names. Don't use top-level Internet domain names on the intranet, such as.

If you use top-level Internet domain names on the intranet, computers on the intranet that are also connected to the Internet may experience resolution errors. A disjointed namespace occurs when a computer's primary DNS suffix doesn't match the DNS domain of which it is a member.

Microsoft DNS Server uses this information when name resolution queries must be resolved by getting information from name servers outside your LAN by contacting name servers on the Internet. You should not change this file unless the name-to-IP-address mappings of the Internet root servers change. If the computer on which you install Microsoft DNS Server does not connect to the Internet, you should delete all the entries in this file and replace them with NS and A records for your intranet root name servers.

The zone file has the same name as the zone. Resource records are added to this file when you configure zone properties and add new records by using DNS Manager.
