Description

The Set-DnsServerZoneAging cmdlet configures aging settings for a Domain Name System (DNS) server zone.

A resource record can remain on a DNS server after the resource is no longer part of the network. Aging settings determine when a record can be removed, or scavenged, as a stale record.

Examples

Example 1: Set a scavenging server

PS C:\> Set-DnsServerZoneAging west01.contoso.com -Aging $True -ScavengeServers 172.18.1.1 -PassThru -Verbose

This command enables aging for a domain named west01.contoso.com and specifies a scavenging server.

Parameters

-Aging

Indicates whether to enable aging and scavenging for a zone. Aging and scavenging are not enabled by default.

For a value of $True, a DNS server refreshes time stamps for resource records when the server receives a dynamic update request. This enables DNS servers to scavenge resource records.

For a value of $False, DNS servers do not refresh time stamps for resource records and do not scavenge resource records.

Type:	Boolean
Aliases:	AgingEnabled
Position:	2
Default value:	None
Required:	False
Accept pipeline input:	True
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
Position:	Named
Default value:	None
Required:	False
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[]
Aliases:	Session
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ComputerName

Specifies a DNS server. If you do not specify this parameter, the command runs on the local system. 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
Aliases:	Cn
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Name

Specifies the name of a zone. This cmdlet is relevant only for primary zones.

Type:	String
Aliases:	ZoneName
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-NoRefreshInterval

Specifies the length of time as a TimeSpan object. 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.

Type:	TimeSpan
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
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
Position:	Named
Default value:	None
Required:	False
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.

If a resource record that has a non-zero time stamp is not refreshed for a period of the sum the values defined in the NoRefreshInterval parameter and the RefreshInterval parameter, a 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. The default value is the same as the DefaultRefreshInterval property of the zone DNS server.

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

-ScavengeServers

Specifies an array of IP addresses for DNS servers. These servers can scavenge records in this zone. If you do not specify any scavenge servers, any primary DNS server that is authoritative for the zone can scavenge.

Type:	IPAddress[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
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
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WhatIf

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

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
