Dns not updating from other dns

The IP address originally used in testing its responsiveness is not included in this list.

Solution: If the server was previously configured to restrict the IP addresses for which it responds to queries, it is possible that the IP address that are being used by clients to contact it is not in the list of restricted IP addresses that are permitted to provide service to clients.

Try testing the server for a response again, but specify a different IP address that is known to be in the restricted interfaces list for the server.

If the DNS server responds for that address, add the missing server IP address to the list.

Cause: The DNS server has been configured to disable the use of its automatically created default reverse lookup zones.

Solution: Verify that automatically created reverse lookup zones have been created for the server or that advanced configuration changes have not been previously made to the server.

By default, DNS servers automatically create the following three standard reverse lookup zones based on Request for Comments (RFC) recommendations.

These zones are created with common IP addresses covered by these zones that are not useful in a reverse lookup search (0.0.0.0, 127.0.0.1, and 255.255.255.255).

Cause: The DNS server has been configured to limit service to a specific list of its configured IP addresses.

Solution: Verify that the server computer has a valid functioning network connection.

First, check that related client hardware (cables and network adapters) are working properly at the client by using basic network and hardware troubleshooting steps.

These features can cause some differences for DNS server defaults—when the DNS database is directory-integrated—that differ from the DNS server defaults that are used with traditional file-based storage.

Many DNS server problems start with failed queries at a client.

This is because disabling the creation of these zones involves advanced manual configuration of the server registry by a user.
