Set-DnsServerScavenging

Last Updated: 3/28/2017

SYNOPSIS

Changes DNS server scavenging settings.

SYNTAX

Set-DnsServerScavenging [-ApplyOnAllZones] [-ComputerName <String>] [[-ScavengingState] <Boolean>]
 [[-RefreshInterval] <TimeSpan>] [[-ScavengingInterval] <TimeSpan>] [[-NoRefreshInterval] <TimeSpan>]
 [-PassThru] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm]
 [<CommonParameters>]

DESCRIPTION

The Set-DnsServerScavenging cmdlet changes scavenging settings on a Domain Name System (DNS) server. If any of the set operations fail, the cmdlet continues to configure other settings. The cmdlet displays the settings that it changed and the settings that it did not change.

EXAMPLES

Example 1: Change the refresh interval for a resource record

PS C:\> Set-DnsServerScavenging -RefreshInterval 1.00:00:00 -Verbose -PassThru

This command changes the refresh interval to 1 day for scavenging on a local DNS server.

PARAMETERS

-ApplyOnAllZones

Indicates that the server settings apply on all zones.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ComputerName

Specifies a remote DNS server. You can specify an IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.

Type: String
Parameter Sets: (All)
Aliases: Cn

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-NoRefreshInterval

Specifies a length of time as a TimeSpan object. 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 8760 hours (seven days).

Type: TimeSpan
Parameter Sets: (All)
Aliases: 

Required: False
Position: 3
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-RefreshInterval

Specifies the refresh interval as a TimeSpan object. 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 8760 hours (seven days). The default value is the same as the DefaultRefreshInterval property of the zone DNS server.

Type: TimeSpan
Parameter Sets: (All)
Aliases: 

Required: False
Position: 2
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-ScavengingInterval

Specifies a length of time as 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 default setting is 0, which 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).

Type: TimeSpan
Parameter Sets: (All)
Aliases: 

Required: False
Position: 4
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-ScavengingState

Specifies whether to Enable automatic scavenging of stale records. ScavengingState determines whether the DNS scavenging feature is enabled by default on newly created zones. The acceptable values for this parameter are:

  • $False. Disables scavenging. This is the default setting.
  • $True. Enables scavenging
Type: Boolean
Parameter Sets: (All)
Aliases: 

Required: False
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type: Int32
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: wi

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

CommonParameters

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.
