DnsServer Module

Modifies recursion settings for a DNS server.

Syntax

Default (Default) 

Set-DnsServerRecursion
    [-ComputerName <String>]
    [-AdditionalTimeout <UInt32>]
    [-RetryInterval <UInt32>]
    [-Timeout <UInt32>]
    [-Enable <Boolean>]
    [-PassThru]
    [-SecureResponse <Boolean>]

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 15 -PassThru

Enable               : False
AdditionalTimeout(s) : 4
RetryInterval(s)     : 15
Timeout(s)           : 8
SecureResponse       : True

This command sets the retry interval to 15 seconds.

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.

Parameter properties

Type:UInt32
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments: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.

Parameter properties

Type:SwitchParameter
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments: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.

Parameter properties

Value from remaining arguments: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.

Parameter properties

Type:String

-Confirm

Prompts you for confirmation before running the cmdlet.

Parameter properties

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False

-Enable

Specifies whether the server enables recursion.

Parameter properties

Type:Boolean
Default value:None
Supports wildcards:False
DontShow:False
Aliases:EnableRecursion

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments:False

-PassThru

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

Parameter properties

Type:SwitchParameter
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments: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.

Parameter properties

Type:UInt32
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments: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.

Parameter properties

Type:Boolean
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:True
Value from remaining arguments: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.

Parameter properties

Type:Int32
Default value:None
Supports wildcards:False
DontShow:False

Parameter sets

(All)
Position:Named
Mandatory:False
Value from pipeline:False
Value from pipeline by property name:False
Value from remaining arguments:False

-Timeout

Specifies 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 0x8 (8 seconds). We recommend that you increase this value when recursion occurs over a slow link.

Parameter properties

Type:UInt32
Default value:None
Supports wildcards:False
DontShow:False
