Description

The DnsServerSetting DSC resource manages the Domain Name System (DNS) server settings and properties.

If the parameter DnsServer is set to 'localhost' then the resource can normally use the default credentials (SYSTEM) to configure the DNS server settings. If using any other value for the parameter DnsServer make sure that the credential the resource is run as have the correct permissions at the target node and the necessary network traffic is permitted (WsMan protocol). It is possible to run the resource with specific credentials using the built-in parameter PsDscRunAsCredential.

The parameter MaximumUdpPacketSize can only be set when DnsServer is set to 'localhost', and after it is changed the DNS Server service will be restarted to make the setting effective - this may cause a short about of downtime.

Please see DnsServerSetting class for more information around the properties this resource supports.

Requirements

  • Target machine must be running Windows Server 2012 or later.
    • Properties RootTrustAnchorsURL and ZoneWritebackInterval is not supported by Windows Server 2012.
    • Properties IgnoreServerLevelPolicies, IgnoreAllPolicies, ScopeOptionValue, and VirtualizationInstanceOptionValue are not supported by Windows Server 2012 and Windows Server 2012 R2.
