DnsServerScavenging .SYNOPSIS The DnsServerScavenging DSC resource manages scavenging on a Microsoft Domain Name System (DNS) server. .DESCRIPTION The DnsServerScavenging DSC resource manages scavenging on a Microsoft Domain Name System (DNS) server. .PARAMETER DnsServer Key - System.String The host name of the Domain Name System (DNS) server, or use 'localhost' for the current node. .PARAMETER ScavengingState Write - Nullable[System.Boolean] Specifies whether to Enable automatic scavenging of stale records. ScavengingState determines whether the DNS scavenging feature is enabled by default on newly created zones. .PARAMETER ScavengingInterval Write - System.String Specifies a length of time as a value that can be converted to a [TimeSpan] object. ScavengingInterval determines whether the scavenging feature for the DNS server is enabled and sets the number of hours between scavenging cycles. The value 0 disables scavenging for the DNS server. A setting greater than 0 enables scavenging for the server and sets the number of days, hours, minutes, and seconds (formatted as dd.hh:mm:ss) between scavenging cycles. The minimum value is 0. The maximum value is 365.00:00:00 (1 year). .PARAMETER RefreshInterval Write - System.String Specifies the refresh interval as a value that can be converted to a [TimeSpan] object (formatted as dd.hh:mm:ss). During this interval, a DNS server can refresh a resource record that has a non-zero time stamp. Zones on the server inherit this value automatically. If a DNS server does not refresh a resource record that has a non-zero time stamp, the DNS server can remove that record during the next scavenging. Do not select a value smaller than the longest refresh period of a resource record registered in the zone. The minimum value is 0. The maximum value is 365.00:00:00 (1 year). .PARAMETER NoRefreshInterval Write - System.String Specifies a length of time as a value that can be converted to a [TimeSpan] object (formatted as dd.hh:mm:ss). NoRefreshInterval sets a period of time in which no refreshes are accepted for dynamically updated records. Zones on the server inherit this value automatically. This value is the interval between the last update of a timestamp for a record and the earliest time when the timestamp can be refreshed. The minimum value is 0. The maximum value is 365.00:00:00 (1 year). .PARAMETER LastScavengeTime Read - Nullable[System.DateTime] The time when the last scavenging cycle was executed. .EXAMPLE 1 This configuration will enable scavenging and change the scavenging intervals on the DNS server. Configuration EnableAndChangeScavengingIntervals_Config { Import-DscResource -ModuleName 'xDnsServer' Node localhost { DnsServerScavenging 'EnableScavengingAndChangeIntervals' { DnsServer = 'localhost' ScavengingState = $true ScavengingInterval = '7.00:00:00' RefreshInterval = '7.00:00:00' NoRefreshInterval = '7.00:00:00' } } } .EXAMPLE 2 This configuration will enable scavenging on the DNS server, using the default interval values. Configuration EnableScavenging_Config { Import-DscResource -ModuleName 'xDnsServer' Node localhost { DnsServerScavenging 'EnableScavenging' { DnsServer = 'localhost' ScavengingState = $true } } } .EXAMPLE 3 This configuration will change scavenging intervals on the DNS server, but does not enforce that scavenging is enabled. Configuration ChangeScavengingIntervals_Config { Import-DscResource -ModuleName 'xDnsServer' Node localhost { DnsServerScavenging 'ChangeScavengingIntervals' { DnsServer = 'localhost' ScavengingInterval = '7.00:00:00' RefreshInterval = '7.00:00:00' NoRefreshInterval = '7.00:00:00' } } } .EXAMPLE 4 This configuration will disable scavenging on the DNS server. Configuration DisableScavenging_Config { Import-DscResource -ModuleName 'xDnsServer' Node localhost { DnsServerScavenging 'DisableScavenging' { DnsServer = 'localhost' ScavengingState = $false } } } |
