Set-DnsServerRecursion

Modifies recursion settings for a DNS server.

   [-AsJob]
   [-CimSession <CimSession[]>]
   [-ComputerName <String>]
   [-Enable <Boolean>]
   [-PassThru]

   [-ThrottleLimit <Int32>]
   [-Timeout <UInt32>]
   [-Confirm]
   [-WhatIf]

Description

The Set-DnsServerRecursion cmdlet modifies recursion settings for a 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.

Examples

Example 1: Set the retry interval

PS C:\> Set-DnsServerRecursion -RetryInterval 3 -PassThru
Enable               : False

AdditionalTimeout(s) : 4

RetryInterval(s)     : 15

Timeout(s)           : 8

SecureResponse       : True

This command sets the retry interval to 3 seconds.

Optional Parameters

-AdditionalTimeout

Specifies the time interval, in seconds, that a DNS server waits as it uses recursion to get resource records from a remote DNS server. We recommend that you limit the value to the range 0x00000000 to 0x0000000F (0 seconds to 15 seconds), inclusive. However, you can use any value. We recommend that you set the default value to 4.

Type:UInt32
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-AsJob

ps_cimcommon_asjob

Type:SwitchParameter
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-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ComputerName

Specifies a DNS server. The acceptable values for this parameter are: an IPv4 address; an IPv6 address; and any other value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
-Enable

Enables or disables recursion.

Type:Boolean
Position:Named
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
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-RetryInterval

Specifies elapsed seconds before a DNS server retries a recursive lookup. If the parameter is undefined or zero, the DNS server retries after three seconds. Valid values are in the range of 1 second to 15 seconds.

We recommend that in general, you do not change the value of this parameter. However, under a few circumstances you should consider changing the parameter 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, you can raise the retry interval to be slightly longer than the observed response time.

Type:UInt32
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-SecureResponse

Indicates whether a DNS server screens DNS records against the zone of authority for the remote server, to prevent cache pollution. If you set this to $True, the DNS server caches only those records that are in the zone of authority for the queried remote server. Otherwise, the server caches all records in the remote server cache.

Type:Boolean
Position:Named
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
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Timeout

Determines 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 0x1 to 0xFFFFFFFF (1 second to 15 seconds). The default setting is 0xF (15 seconds). We recommend that you increase this value when recursion occurs over a slow link.

Type:UInt32
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-WhatIf

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

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