Applies To: Windows 8.1, Windows PowerShell 4.0, Windows Server 2012 R2

Remove-RemoteAccessRadius

Removes an external RADIUS server from being used for VPN authentication, accounting for both DirectAccess (DA) and VPN, or one-time password (OTP) authentication for DA.

Syntax

Parameter Set: Remove2
Remove-RemoteAccessRadius [-ServerName] <String> [-Purpose] <String> [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-EntrypointName <String> ] [-PassThru] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Remove-RemoteAccessRadius cmdlet removes an external RADIUS server from being used for VPN authentication, Accounting for both DirectAccess (DA) and VPN, or one-time password (OTP) authentication for DA as follows.
-- Accounting RADIUS configuration applies to both DA and VPN.
-- OTP RADIUS configuration applies only to DA.
-- Authentication RADIUS configuration applies only to VPN.

A RADIUS server configuration for Accounting and OTP are global in nature, such that the configurations apply to the entire Remote Access deployment. RADIUS server configuration for VPN applies only to a specific VPN server, and all servers in a load balancing cluster, or if multi-site is deployed, to all VPN servers at a site.

The following behaviors describe aspects of this cmdlet.
-- If a RADIUS server is currently being used for multiple purposes, then it can be removed for one or more of the purposes. However, the cmdlet would have to be run separately for each purpose.
-- If the last RADIUS server being used for accounting is removed, then the accounting type automatically switches to Windows accounting.
-- The User is not allowed to delete the last RADIUS server being used for VPN authentication if Radius authentication is configured.
-- When RADIUS accounting or RADIUS authentication is disabled, using the Set-RemoteAccessAccounting and Set-VpnAuthType cmdlets, then the RADIUS servers is use do not show up in the configuration and therefore cannot be explicitly removed.

Parameters

-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<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<String>

Specifies the IPv4 or IPv6 address, or host name, of the computer on which the Remote Access server computer specific tasks should be run. If this parameter is specified when removing a RADIUS server for authentication, then it is removed for the VPN server represented by this parameter.

-EntrypointName<String>

Specifies a site in a multi-site deployment. It is applicable only to RADIUS server configuration for VPN authentication. It is not applicable to RADIUS accounting and OTP.
When the parameter is specified it indicates that the Radius server for VPN authentication should be removed for that site.
If this parameter is not specified in a multi-site deployment, then this parameter value on which the cmdlet is run is used. The server could also be represented by using the ComputerName parameter.
If this parameter and ComputerName are specified and the ComputerName does not belong to the site represented by this parameter, then this parameter takes precedence and the RADIUS server is removed from it.

-ThrottleLimit<Int32>

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.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • None

Outputs

The output type is the type of the objects that the cmdlet emits.

  • Microsoft.Management.Infrastructure.CimInstance#RemoteAccessRadiusServerPurpose[]

    The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

    -- The IPv4 or IPv6 address of the RADIUS server that was removed.
    -- The purpose for which the server was removed.


Examples

EXAMPLE 1

This example removes a RADIUS server from being used for authentication. The RADIUS server named 10.1.1.1 is being used for both authentication and accounting. This cmdlet removes the server from being used for authentication.
