Enable-PSRemoting

Updated: May 8, 2014

Applies To: Windows PowerShell 4.0

Enable-PSRemoting

Configures the computer to receive remote commands.

Syntax

Parameter Set: Default
Enable-PSRemoting [-Force] [-SkipNetworkProfileCheck] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Enable-PSRemoting cmdlet configures the computer to receive Windows PowerShell remote commands that are sent by using the WS-Management technology.

On Windows Server® 2012, Windows PowerShell remoting is enabled by default. You can use Enable-PSRemoting to enable Windows PowerShell remoting on other supported versions of Windows and to re-enable remoting on Windows Server 2012 if it becomes disabled.

You need to run this command only once on each computer that will receive commands. You do not need to run it on computers that only send commands. Because the configuration activates listeners, it is prudent to run it only where it is needed.

Beginning in Windows PowerShell 3.0, the Enable-PSRemoting cmdlet can enable Windows PowerShell remoting on client versions of Windows when the computer is on a public network. For more information, see the description of the SkipNetworkProfileCheck parameter.

The Enable-PSRemoting cmdlet performs the following operations:

-- Runs the Set-WSManQuickConfig cmdlet, which performs the following tasks:

----- Starts the WinRM service.

----- Sets the startup type on the WinRM service to Automatic.

----- Creates a listener to accept requests on any IP address.

----- Enables a firewall exception for WS-Management communications.

----- Registers the Microsoft.PowerShell and Microsoft.PowerShell.Workflow session configurations, if it they are not already registered.

----- Registers the Microsoft.PowerShell32 session configuration on 64-bit computers, if it is not already registered.

----- Enables all session configurations.

----- Changes the security descriptor of all session configurations to allow remote access.

----- Restarts the WinRM service to make the preceding changes effective.

To run this cmdlet, start Windows PowerShell with the "Run as administrator" option.

CAUTION: On systems that have both Windows PowerShell 3.0 and the Windows PowerShell 2.0 engine, do not use Windows PowerShell 2.0 to run the Enable-PSRemoting and Disable-PSRemoting cmdlets. The commands might appear to succeed, but the remoting is not configured correctly. Remote commands, and later attempts to enable and disable remoting, are likely to fail.

Parameters

-Force

Suppresses all user prompts. By default, you are prompted to confirm each operation.

-SkipNetworkProfileCheck

Enables remoting on client versions of Windows when the computer is on a public network. This parameter enables a firewall rule for public networks that allows remote access only from computers in the same local subnet.

This parameter has no effect on server versions of Windows, which, by default, have a local subnet firewall rule for public networks. If the local subnet firewall rule is disabled on a server version of Windows, Enable-PSRemoting re-enables it, regardless of the value of this parameter.

To remove the local subnet restriction and enable remote access from all locations on public networks, use the Set-NetFirewallRule cmdlet in the NetSecurity module. For more information, see Notes and Examples.

This parameter is introduced in Windows PowerShell 3.0.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see  about_CommonParameters (http://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

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

  • None

    You cannot pipe input to this cmdlet.


Outputs

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

  • System.String

    Enable-PSRemoting returns strings that describe its results.


Notes

  • In Windows PowerShell 3.0, Enable-PSRemoting creates the following firewall exceptions for WS-Management communications.

    On server versions of Windows, Enable-PSRemoting creates firewall rules for private and domain networks that allow remote access, and creates a firewall rule for public networks that allows remote access only from computers in the same local subnet.

    On client versions of Windows, Enable-PSRemoting in Windows PowerShell 3.0 creates firewall rules for private and domain networks that allow unrestricted remote access. To create a firewall rule for public networks that allows remote access from the same local subnet, use the SkipNetworkProfileCheck parameter.

    On client or server versions of Windows, to create a firewall rule for public networks that removes the local subnet restriction and allows remote access , use the Set-NetFirewallRule cmdlet in the NetSecurity module to run the following command: Set-NetFirewallRule –Name "WINRM-HTTP-In-TCP-PUBLIC" –RemoteAddress Any

  • In Windows PowerShell 2.0, Enable-PSRemoting creates the following firewall exceptions for WS-Management communications.

    On server versions of Windows, it creates firewall rules for all networks that allow remote access.

    On client versions of Windows, Enable-PSRemoting in Windows PowerShell 2.0 creates a firewall exception only for domain and private network locations. To minimize security risks, Enable-PSRemoting does not create a firewall rule for public networks on client versions of Windows. When the current network location is public, Enable-PSRemoting returns the following message: "Unable to check the status of the firewall."

  • Beginning in Windows PowerShell 3.0, Enable-PSRemoting enables all session configurations by setting the value of the Enabled property of all session configurations (WSMan:\<ComputerName>\Plugin\<SessionConfigurationName>\Enabled) to True ($true).

  • In Windows PowerShell 2.0, Enable-PSRemoting removes the Deny_All setting from the security descriptor of session configurations. In Windows PowerShell 3.0, Enable-PSRemoting removes the Deny_All and Network_Deny_All settings, thereby providing remote access to session configurations that were reserved for local use.

Examples

-------------------------- EXAMPLE 1 --------------------------

This command configures the computer to receive remote commands.


PS C:\> Enable-PSRemoting

-------------------------- EXAMPLE 2 --------------------------

This command configures the computer to receive remote commands. It uses the Force parameter to suppress the user prompts.


PS C:\> Enable-PSRemoting -Force

Example 3

This example shows how to allow remote access from public networks on client versions of Windows. Before using these commands, analyze the security setting and verify that the computer network will be safe from harm.

The first command enables remoting in Windows PowerShell. By default, this creates network rules that allow remote access from private and domain networks. The command uses the SkipNetworkProfileCheck parameter to allow remote access from public networks in the same local subnet. The command uses the Force parameter to suppress confirmation messages.

The SkipNetworkProfileCheck parameter has no effect on server version of Windows, which allow remote access from public networks in the same local subnet by default.

The second command eliminates the subnet restriction. The command uses the Set-NetFirewallRule cmdlet in the NetSecurity module to add a firewall rule that allows remote access from public networks from any remote location, including locations in different subnets.


PS C:\> Enable-PSRemoting -SkipNetworkProfileCheck -Force

PS C:\>Set-NetFirewallRule –Name "WINRM-HTTP-In-TCP-PUBLIC" –RemoteAddress Any
