Microsoft DnsServer reference: Modifies recursion settings for a DNS server. The syntax and selected example below are adapted from the pinned Windows Server 2025 reference. Module availability, target configuration and delegated permissions determine whether it can run in your environment. Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.
Use an account with the target resource permissions documented for Set-DnsServerRecursion. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

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.
-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.
-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.
-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.
-Confirm
Prompts you for confirmation before running the cmdlet.
-Enable
Specifies whether the server enables recursion.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-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.
-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.
-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.
-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.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Prerequisites
Windows with the DnsServer module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
Security considerations
This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
