Microsoft VpnClient reference: Changes DNS servers for an existing DNS suffix. 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.

Set-VpnConnectionTriggerDnsConfiguration [-ConnectionName] <String> [[-DnsSuffix] <String>]
 [[-DnsIPAddress] <String[]>] [[-DnsSuffixSearchList] <String[]>] [-PassThru] [-Force]
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf] [-Confirm] [<CommonParameters>]

Required permissions

Use an account with the target resource permissions documented for Set-VpnConnectionTriggerDnsConfiguration. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Supported environments

Windows / VpnClient · Windows Server 2025 documentation; feature/module prerequisites apply

Parameters

-AsJob

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

-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.

-Confirm

Prompts you for confirmation before running the cmdlet.

-ConnectionName (required)

Specifies the name of a VPN connection profile. To view existing VPN connection profiles, use the Get-VpnConnection cmdlet.

-DnsIPAddress

Specifies an array IP addresses of DNS servers for the DNS suffix. You can use both IPv4 and IPv6 addresses. If you specify an empty string, when the client accesses a resource in the DNS suffix, it does not trigger a VPN connection.

-DnsSuffix

Specifies a DNS suffix.

-DnsSuffixSearchList

Specifies an array of DNS suffixes. The client appends a suffix to a short name to create a fully qualified domain name (FQDN). The client tries the suffixes on this list to see if any of them, appended to a short name, identify a resource.

-Force

Indicates that the cmdlet makes changes to the VPN connection trigger DNS configuration without a confirmation message.

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output. If you specify this parameter, the cmdlet returns the VpnConnectionTriggerDnsConfiguration object that contains DNS suffixes and corresponding DNS servers, and the DNS suffix search list.

-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.

-WhatIf

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

Prerequisites

Windows with the VpnClient 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.

Examples

Set-VpnConnectionTriggerDnsConfiguration -ConnectionName "Contoso" -DnsSuffix "washington.contoso.com" -DnsIPAddress "172.16.12.3" -PassThru -Force
