SHORT DESCRIPTION
Describes the system requirements and configuration requirements for
running remote commands in Windows PowerShell.
LONG DESCRIPTION
This topic describes the system requirements, user requirements, and
resource requirements for establishing remote connections and running
remote commands in Windows PowerShell. It also provides instructions for
configuring remote operations.
Note: Many cmdlets (including the Get-Service, Get-Process, Get-WMIObject,
Get-EventLog, and Get-WinEvent cmdlets) get objects from remote
computers by using Microsoft .NET Framework methods to retrieve the
objects. They do not use the Windows PowerShell remoting
infrastructure. The requirements in this document do not apply to
these cmdlets.
To find the cmdlets that have a ComputerName parameter but do not use
Windows PowerShell remoting, read the description of the ComputerName
parameter of the cmdlets.
SYSTEM REQUIREMENTS
The local and remote computers must have:
-- Windows PowerShell 2.0 or later
-- The Microsoft .NET Framework 2.0 or later
-- Windows Remote Management 2.0
To find the version number of an installed version of Windows PowerShell,
use the $PSVersionTable automatic variable. The value of the
$PSVersionTable.Version.Major property must be at least 2.
Windows Remote Management 2.0 is included in Windows 7 and in
Windows Server 2008 R2. It is also included in the integrated installation
package for earlier versions of Windows that includes Windows PowerShell.
Windows PowerShell Integrated Scripting Environment (ISE) and the
Out-Gridview cmdlet require the Microsoft .NET Framework 3.5 with Service
Pack 1. The Get-WinEvent cmdlet requires the Microsoft .NET Framework 3.5
or greater. These upgrades are not required for remoting.
USER PERMISSIONS
To establish a remote connection and run remote commands, the current user
must be a member of the Administrators group on the remote computer. Or,
the current user must be able to provide the credentials of an
administrator.
WINDOWS NETWORK LOCATION
To enable remoting on client versions of Windows, such as Windows 7,
the current Windows network location must be Domain or Private ("Home"
or "Work"). If the network location is Public, Windows PowerShell
cannot create the required firewall exception for WS-Management
communication.
RUN AS ADMINISTRATOR
In Windows Vista, Windows Server 2008, and later versions of Windows,
Administrator privileges are required for the following remoting
operations:
-- Establishing a remote connection to the local computer. This is
commonly known as a "loopback" scenario.
-- Managing session configurations on the local computer.
-- Viewing and changing WS-Management settings on the local computer.
These are the settings in the LocalHost node of the WSMAN: drive.
To perform these tasks, you must start Windows PowerShell with the "Run
as administrator" option even if you are a member of the Administrators
group on the local computer.
In Windows 7 and in Windows Server 2008 R2, to start Windows PowerShell
with the "Run as administrator" option:
1. Click Start, click All Programs, click Accessories, and then click
the Windows PowerShell folder.
2. Right-click Windows PowerShell, and then click
"Run as administrator".
In Windows Vista and Windows Server 2008, to start Windows PowerShell with
the "Run as administrator" option:
1. Click Start, click All Programs, and then click the Windows
PowerShell folder.
2. Right-click Windows PowerShell, and then click
"Run as administrator".
The "Run as administrator" option is also available in other Windows
Explorer entries for Windows PowerShell, including shortcuts. Just
right-click the item, and then click "Run as administrator".
When you start Windows PowerShell from another program such as Cmd.exe, use
the "Run as administrator" option to start the program.
HOW TO CONFIGURE YOUR COMPUTER FOR REMOTING
The remoting features of Windows PowerShell are supported by the WinRM
service, which is the Microsoft implementation of the Web Services for
Management (WS-Management) protocol. To use the remoting features, you
need to change the default configuration of WS-Management on the system.
To configure Windows PowerShell to receive remote commands:
1. Start Windows PowerShell. In Windows Vista and later versions of
Windows, start Windows PowerShell with the "Run as administrator"
option.
2. At the command prompt, type:
enable-psremoting
This procedure allows users on other computers to establish remote
connections and to run remote commands on the local computer. It also
allows you to create a "loopback" connection on the local computer.
To verify that remoting is configured correctly, run a test command such as
the following command, which creates a remote session on the local
computer.
new-pssession
If remoting is configured correctly, the command will create a session on
the local computer and return an object that represents the session. The
output should resemble the following sample output:
C:\PS> new-pssession
Id Name ComputerName State ConfigurationName
-- ---- ------------ ----- -----
1 Session1 localhost Opened Microsoft.PowerShell
If the command fails, see about_Remote_Troubleshooting for assistance.
UNDERSTAND POLICIES
When you work remotely, you use two instances of Windows PowerShell, one
on the local computer and one on the remote computer. As a result, your
work is affected by the Windows policies and the Windows PowerShell
policies on the local and remote computers.
In general, before you connect and as you are establishing the connection,
the policies on the local computer are in effect. When you are using the
connection, the policies on the remote computer are in effect.
