DNS Server Configuration

Applies To: Windows Server 2008

The DNS server configuration consists of the settings that determine how the DNS server will function on a network and how those settings are stored and retrieved when they are needed.

 

Events

Event ID Source Message

150

Microsoft-Windows-DNS-Server-Service

The DNS server could not load or initialize the plug-in DLL %1. The event data is the error code returned by the plug-in DLL load or initialization attempt. Please correct the plug-in error that is causing this condition or remove the plug-in from the DNS server configuration.

408

Microsoft-Windows-DNS-Server-Service

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 machine 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 machine, make sure that no other application (e.g. another DNS server) is running that would attempt to use the DNS port.

For more information, see "DNS server log reference" in the online Help.

409

Microsoft-Windows-DNS-Server-Service

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 "To restrict a DNS server to listen only on selected addresses" in the online Help.

410

Microsoft-Windows-DNS-Server-Service

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 machine.

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 "To restrict a DNS server to listen only on selected addresses" in the online Help.

414

Microsoft-Windows-DNS-Server-Service

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

You might have forgotten to configure a primary DNS domain for the server computer. For more information, see either "DNS server log reference" or "To configure the primary DNS suffix for a client computer" 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) open System applet
3) select Computer Name tab
4) click the "Change" button and join the computer to a domain or workgroup; this name will be used as your DNS domain name
5) reboot to initialize with new domain name

After 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.

6702

Microsoft-Windows-DNS-Server-Service

DNS server has updated its own host (A) records. In order to ensure that its DS-integrated peer DNS servers are able to replicate with this server, an attempt was made to update them with the new records through dynamic update. An error was encountered during this update, the record data is the error code.

If this DNS server does not have any DS-integrated peers, then this error
should be ignored.

If this DNS server's Active Directory replication partners do not have the correct IP address(es) for this server, they will be unable to replicate with it.

To ensure proper replication:
1) Find this server's Active Directory replication partners that run the DNS server.
2) Open DnsManager and connect in turn to each of the replication partners.
3) On each server, check the host (A record) registration for THIS server.
4) Delete any A records that do NOT correspond to IP addresses of this server.
5) If there are no A records for this server, add at least one A record corresponding to an address on this server, that the replication partner can contact. (In other words, if there multiple IP addresses for this DNS server, add at least one that is on the same network as the Active Directory DNS server you are updating.)
6) Note, that is not necessary to update EVERY replication partner. It is only necessary that the records are fixed up on enough replication partners so that every server that replicates with this server will receive (through replication) the new data.

The global query block list is a feature that prevents attacks on your network by blocking DNS queries for specific host names. This feature has caused the DNS server to fail a query with error code NAME ERROR for %1 even though data for this DNS name exists in the DNS database. Other queries in all locally authoritative zones for other names that begin with labels in the block list will also fail, but no event will be logged when further queries are blocked until the DNS server service on this computer is restarted. See product documentation for information about this feature and instructions on how to configure it.

Below is the current global query block list (this list may be truncated in this event if it is too long):
