DnsServerRecursion

DnsServerRecursion

Parameters

Parameter	Attribute	DataType	Description	Allowed Values
DnsServer	Key	System.String	The host name of the Domain Name System (DNS) server, or use 'localhost' for the current node.
Enable	Write	Nullable[System.Boolean]	Specifies whether the server enables recursion.
AdditionalTimeout	Write	Nullable[System.UInt32]	Specifies the time interval, in seconds, that a DNS server waits as it uses recursion to get resource records from a remote DNS server. Valid values are in the range of 1 second to 15 seconds. See recommendation in the documentation of Set-DnsServerRecursion.
RetryInterval	Write	Nullable[System.UInt32]	Specifies elapsed seconds before a DNS server retries a recursive lookup. Valid values are in the range of 1 second to 15 seconds. The recommendation is that in general this value should not be change. However, under a few circumstances it can be considered changing the value. For example, if a DNS server contacts a remote DNS server over a slow link and retries the lookup before it gets a response, it could help to raise the retry interval to be slightly longer than the observed response time. See recommendation in the documentation of Set-DnsServerRecursion.
Timeout	Write	Nullable[System.UInt32]	Specifies the number of seconds that a DNS server waits before it stops trying to contact a remote server. The valid value is in the range of 1 second to 15 seconds. Recommendation is to increase this value when recursion occurs over a slow link. See recommendation in the documentation of Set-DnsServerRecursion.
Reasons	Read	DnsServerReason[]	Returns the reason a property is not in desired state.

Description

The DnsServerRecursion DSC resource manages recursion settings on a Microsoft Domain Name System (DNS) server. Recursion occurs when a DNS server queries other DNS servers on behalf of a requesting client, and then sends the answer back to the client.

The property SecureResponse that can be set by the cmdlet Set-DnsServerRecursion changes the same value as EnablePollutionProtection in the resource DnsServerCache does. Use the property EnablePollutionProtection in the resource DnsServerCache to enforce pollution protection.
