This command also modifies the configuration of the specified server. Accepts server-level and zone-level settings.

The registry editor bypasses standard safeguards, allowing settings that can degrade performance, damage your system, or even require you to reinstall Windows. You can safely alter most registry settings by using the programs in Control Panel or Microsoft Management Console mmc.

If you must edit the registry directly, back it up first. Read the registry editor help for more information. Modifies the configuration of the specified zone. The zone name must be specified only for zone-level parameters. Creates a DNS application directory partition. When DNS is installed, an application directory partition for the service is created at the forest and domain levels.

Use this command to create DNS application directory partitions that were deleted or never created. With no parameter, this command creates a built-in DNS directory partition for the domain. This operation creates additional DNS application directory partitions. Lists the zones that exist on the specified DNS server.

The enumzones parameters act as filters on the list of zones. If no filters are specified, a complete list of zones is returned. Example 2: Display a complete list of zones on a DNS server. Example 3: Display a list of autocreated zones on a DNS server. Creates a text file that lists the configuration details of a DNS server. The text file is named DnsSettings. To display zone-level registry settings, use the dnscmd zoneinfo command.

Tests whether an IP address identifies a functioning DNS server or whether the DNS server can act as a forwarder, a root hint server, or a primary server for a specific zone. Example 6: Delete the records from a node. NOTE] After you add a record, make sure that you use the correct data type and data format.

For a list of resource record types and the appropriate data types, see Dnscmd Examples. This means that the DNS server forwards unresolved queries only to the DNS servers in the list, and it does not attempt iterative queries if the forwarders do not resolve them.

You can use the resetforwarders command for internal servers in a network to forward their unresolved queries to one DNS server that has an external connection.

Successful completion of this command starts a scavenge immediately. If the scavenge fails, no warning message appears. Although the command to start the scavenge appears to complete successfully, the scavenge does not start unless the following preconditions are met:. For information about how to restart a paused zone, see the zoneresume parameter in this article.

For information about how to check resource records for a time stamp, see the ageallrecords parameter in this article. Example Checks the DNS server memory for changes, and writes them to persistent storage. The writebackfiles command updates all dirty zones or a specified zone.

This is a server-level operation that checks all zones. You can specify one zone in this operation or you can use the zonewriteback operation.

Creates a text file that lists the resource records of a specified zone. The zoneexport operation creates a file of resource records for an active directory integrated zone for troubleshooting purposes. Example Display RefreshInterval setting from the registry.

Example Display Aging setting from the registry. The zonerefresh command forces a check of the version number in the primary server s start of authority SOA resource record.

If the version number is the same, no zone transfer occurs. The forced check occurs by default every 15 minutes. To change the default, use the dnscmd config refreshinterval command.

Resets the IP addresses of the primary server that provides zone transfer information to a secondary zone. If a zone is hosted on more than one DNS server, you can use this command to reduce the number of times a zone is scavenged. Specifies a list of IP addresses of secondary servers to which a primary server responds when it is asked for a zone transfer. Checks DNS server memory for changes that are relevant to a specified zone, and writes them to persistent storage. About xCyclopedia Github Toggle search Toggle menu.

In future versions of Windows , Microsoft might remove dnscmd. If you currently use dnscmd. Enter your search term Name : Dnscmd. If this parameter is omitted, the local server is used. Specify a setting and, as an option, a value. Parameter values use this syntax: parameter [ value ].

Each event type is represented by a hexadecimal number. If you want more than one event in the log, use hexadecimal addition to add the values, and then enter the sum. If the 0x0 setting is used, the DNS server does not cache records. The default setting is 0x 86, seconds or 1 day. The default setting is 0x seconds. The default setting is 0x3 three seconds.

This value should be increased when recursion occurs over a slow wide area network WAN link. The default setting is 0xF 15 seconds. This value should be increased when recursion occurs over a slow WAN link. Instead, it returns the first record to every query. The default setting is 0x0 , which disables scavenging for the DNS server.

A setting greater than 0x0 enables scavenging for the server and sets the number of hours between scavenging cycles. The default setting is 0x0 , which means that the port number is selected randomly.

When DllPath specifies the fully qualified path name of a valid DNS server plug-in, the DNS server calls functions in the plug-in to resolve name queries that are outside the scope of all locally hosted zones. If a queried name is out of the scope of the plug-in, the DNS server performs name resolution using forwarding or recursion, as configured.

If DllPath is not specified, the DNS server ceases to use a custom plug-in if a custom plug-in was previously configured. The error is recorded in the DNS log. If you want more than one record type to be prohibited in the log, use hexadecimal addition to add the values, and then enter the sum.

During secure dynamic update, excludes root name server NS resource records and start of authority SOA resource records. Allows delegations and server host updates. The default value is 0x1E 30 seconds. After the time-out value expires, the connection is terminated. Parameter values use this syntax: ZoneName Parameter [ Value ]. Name server NS resource records that were previously registered for this zone are not affected.

Therefore, you must remove them manually if you do not want them. This value overrides the value that is set at the server level. Creates a DNS application directory partition. When DNS is installed, an application directory partition for the service is created at the forest and domain levels. Use this command to create DNS application directory partitions that were deleted or never created. With no parameter, this command creates a built-in DNS directory partition for the domain. This operation creates additional DNS application directory partitions.

Creates a text file that lists the configuration details of a DNS server. The text file is named DnsSettings. If a setting is not specified, a report of common settings is returned. Tests whether an IP address identifies a functioning DNS server or whether the DNS server can act as a forwarder, a root hint server, or a master server for a specific zone.

You can specify any of the following tests:. See Example 6: Delete the records from a node. When you add a record, make sure that you use the correct data type and data format. For a list of resource record types and the appropriate data types, see Resource records reference. Because nodes can have more than one resource record, this command requires you to be very specific about the type of resource record that you want to delete.

If you specify a data type and you do not specify a type of resource record data, all records with that specific data type for the specified node are deleted.
