Disable-PSSessionConfiguration

Updated: April 21, 2010

Applies To: Windows PowerShell 2.0

Denies access to the session configurations on the local computer.

Syntax

Disable-PSSessionConfiguration [[-Name] <string[]>] [-Force] [-Confirm] [-WhatIf] [<CommonParameters>]

Description

The Disable-PSSessionConfiguration cmdlet prevents all users of the computer from using the session configuration in a session. This is an advanced cmdlet that is designed to be used by system administrators to manage customized session configurations for their users.

The Disable-PSSessionConfiguration cmdlet adds a "deny all" setting to the security descriptor of one or more registered session configurations. As a result, you can unregister, view, and change the configurations, but you cannot use them in a session.

Without parameters, Disable-PSSessionConfiguration disables the Microsoft.PowerShell configuration, which is the default configuration that is used for sessions. Unless the user specifies a different configuration, both local and remote users are effectively prevented from creating any sessions that connect to the computer.

To disable all session configurations on the computer, use Disable-PSRemoting.

Description
-----------
This example shows the effect of disabling a session configuration.

The first command uses the Get-SessionConfiguration and Format-Table cmdlets to display only the Name and Permission properties of the session configuration objects. This table format makes it easier to see the values of the objects. The results show that members of the Administrators group are permitted to use the session configurations.

The second command uses the Disable-PSSessionConfiguration cmdlet to disable the MaintenanceShell session configuration. The command uses the Force parameter to suppress all user prompts.

The third command repeats the first command. The results show that you can still get the object that represents the MaintenanceShell session configuration even though everyone is denied access to it. The "AccessDenied" entry takes precedence over all other entries in the security descriptor.

The fourth command uses the Set-PSSessionConfiguration cmdlet to increase the MaximumDataSizePerCommandMB setting on the MaintenanceShell session configuration to 60. The results show that the command was successful even though everyone is denied access to the configuration.

The fifth command attempts to use the MaintenanceShell session configuration in a session. It uses the New-PSSession cmdlet to create a new session and the ConfigurationName parameter to specify the MaintenanceShell configuration. The results show that the  New-PSSession command fails because the user is denied access to the configuration.
