408
MessageId=408

Severity=Error

SymbolicName=DNS_EVENT_OPEN_SOCKET_FOR_ADDRESS

The DNS server could not open socket for address %1. Verify that this is a valid IP address for the server computer. If it is not valid use the Interfaces dialog under Server Properties in the DNS Manager to remove it from the list of IP interfaces. Then stop and restart the DNS server. (If this was the only IP interface on this computer and the DNS server may not have started as a result of this error. In that case remove the DNS\Parameters\ListenAddress value in the services section of the registry and restart.) If this is a valid IP address for this computer, make sure that no other program (e.g. another DNS server) is running that would attempt to use the DNS port. For more information, see &quot;DNS server log reference&quot; in the online Help.

409
MessageId=409

Severity=Warning

SymbolicName=DNS_EVENT_UPDATE_LISTEN_ADDRESSES

The DNS server list of restricted interfaces contains IP addresses that are not configured for use at the server computer. Use the DNS manager server properties, interfaces dialog, to verify and reset the IP addresses the DNS server should listen on. For more information, see &quot;To restrict a DNS server to listen only on selected addresses&quot; in the online Help.

410
MessageId=410

Severity=Error

SymbolicName=DNS_EVENT_INVALID_LISTEN_ADDRESSES

The DNS server list of restricted interfaces does not contain a valid IP address for the server computer. The DNS server will use all IP interfaces on the computer. Use the DNS manager server properties, interfaces dialog, to verify and reset the IP addresses the DNS server should listen on. For more information, see &quot;To restrict a DNS server to listen only on selected addresses&quot; in the online Help.

411
MessageId=411

Severity=Error

SymbolicName=DNS_EVENT_HOSTENT_MAX_IPS

The DNS server did not bind to all IP addresses available on this server. Please use the DnsManger server properties interfaces tab to edit the list of IP addresses on which DNS is running. Add any missing IP addresses to the list. After adding any additional IP addresses to the interfaces list, you MUST stop and restart the DNS service for the new interfaces to receive DNS service. For more information, see &quot;To restrict a DNS server to listen only on selected addresses&quot; in the online Help. Note that each additional IP interface does consume system resources and adds a small performance overhead to query reception. There is no benefit in DNS to additional addresses beyond those necessary to support the available network cards. Even if the DNS server is handling multiple zones registered with the Internic, it is not necessary to have different IPs registered for each zone. Hence, although the individual effect is small, since a very large number of IP interfaces may degrade performance, you are encouraged to remove from the computer any IP addresses that are unnecessary.

412
MessageId=412

Severity=Warning

SymbolicName=DNS_EVENT_MANY_IP_INTERFACES

The DNS server is bound to a large number of IP addresses. Each of these server IP addresses consumes additional system resources and can add a slight increase in performance overhead for DNS query reception. In most cases, you can remove secondary IP addresses that are not required to support server networking hardware. For more information, see &quot;Configuring multihomed servers&quot; in the online Help.

413
MessageId=413

Severity=Warning

SymbolicName=DNS_EVENT_NON_DNS_PORT

The DNS server will send requests to other DNS servers on a port other than its default port (TCP port 53). This is done to accommodate configuration changes you have made at the DNS server and prevent it from failing to receive DNS queries it makes to other servers. You might want to change this behavior. For more information, see &quot;DNS server log reference&quot; in the online Help.

This DNS server is multi-homed (running on multiple IP addresses), but has been configured not to run on ALL IP addresses available on the computer. Under these conditions it is impossible to guarantee that a DNS query to a remote DNS server will be sent with one the IP addresses the DNS server is using, and hence, whether the response to that IP address, will be received on the DNS port. To avoid this problem, sends to other DNS servers will be done on a arbitrary (non-DNS) port, and the response will be received regardless of the IP address used.

If you want to use the DNS port for sends to other DNS servers, then you must change your configuration to either:

Use all IP addresses on the computer for DNS (eliminate the listen address list)

-or-

Limit the DNS server to use a single IP address

414
MessageId=414

Severity=Warning

SymbolicName=DNS_EVENT_SINGLE_LABEL_HOSTNAME

The DNS server computer currently has no DNS domain name. Its DNS name is a single label hostname with no domain (example: &quot;host&quot; rather than &quot;host.microsoft.com&quot;).

You might have forgotten to configure a primary DNS domain for the server computer. For more information, see either &quot;DNS server log reference&quot; or &quot;To configure the primary DNS suffix for a client computer&quot; in the online Help.

While the DNS server has only a single label name, all zones created will have default records (SOA and NS) created using only this single label name for the server's hostname. This can lead to incorrect and failed referrals when clients and other DNS servers use these records to locate this server by name.

To correct this problem:


 * 1) Open Control Panel.
 * 2) Start the System tool.
 * 3) Click the Network Identification tab.
 * 4) Click Properties.
 * 5) Type a domain name or work group name. This is used as your DNS domain name.
 * 6) Reboot the computer to initialize with new domain name.

After the reboot, the DNS server will attempt to fix up default records, substituting new DNS name of this server, for old single label name. However, you should review to make sure zone's SOA and NS records now properly use correct domain name of this server.
