Microsoft RemoteAccess reference: Edits the properties associated with an external RADIUS server being used for VPN authentication, accounting for DirectAccess (DA) and VPN, and one-time password (OTP) authentication for DA. 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-RemoteAccessRadius. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-AccountingOnOffMsg
Specifies the enabled state for sending of accounting on and off messages. The acceptable values for this parameter are: -- Enabled. -- Disabled. This parameter is applicable only when the RADIUS server is being added for RA accounting.
-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.
-ComputerName
Specifies the IPv4 or IPv6 address, or host name, of the computer on which the RA server computer specific tasks should be run.
-Confirm
Prompts you for confirmation before running the cmdlet.
-EntrypointName
Specifies a site in a multi-site deployment. This parameter is applicable only to RADIUS server configuration for VPN authentication. This parameter is not applicable to RADIUS accounting and OTP. If this parameter is specified when editing, then it indicates that the properties of the RADIUS server for VPN authentication should be modified for that site. If an entry point is not specified in a multi-site deployment, then the entry point to which the server on which the cmdlet is run belongs is used. The server could also be represented by using the ComputerName parameter. If this parameter and the ComputerName parameter are specified and the ComputerName parameter does not belong to the site represented by this parameter, then this parameter takes precedence and the RADIUS server is added to it.
-MsgAuthenticator
Specifies the enabled state for the usage of message authenticator. The acceptable values for this parameter are: -- Enabled. -- Disabled. This parameter is applicable only when the RADIUS server is being added for VPN authentication.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-Port
Specifies the port number on which the RADIUS server is accepting authentication requests.
-Purpose (required)
Specifies the purpose of the RADIUS server for which the settings are being modified. The acceptable values for this parameter are: -- Authentication. -- Accounting. -- Otp.
-Score
Specifies the initial score.
-ServerName (required)
Specifies the IPv4 or IPv6 address, or host name, of the external RADIUS server for which the properties are being modified for the specified purpose.
-SharedSecret
Specifies the shared secret between the VPN server and the specified external RADIUS server. Note: The secret is specified in plain text.
-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 time-out value, in seconds.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Prerequisites
Windows with the RemoteAccess 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.
This example configures time out and shared secret properties of the RADIUS server named 10.1.2.1 that is being used for the purpose of VPN authentication. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
