Question

How I can add Add-PSSnapin Microsoft.SharePoint.PowerShell to machine without SharePoint 2010? I try to run PowerShell script to Backup Farm on Windows Server 2008 R2 without Sharepoint but while I open PowerShell and try to run script I always have error:

Add-PSSnapin : No snap-ins have been registered for Windows PowerShell version 2. At line:1 char:13 + Add-PSSnapin <<<< Microsoft.SharePoint.PowerShell + CategoryInfo : InvalidArgument: (Microsoft.SharePoint.PowerShell:String) [Add-PS ption + FullyQualifiedErrorId : AddPSSnapInRead,Microsoft.PowerShell.Commands.AddPSSnapinCommand

Answer 1

You can also do Implicit Remoting, which allows you to import all of the SP10 Powershell commands into a local session. The method described above works as well, but you are essentially running the commands from the server, so if you are on a server with different modules (such as Exchange 2010) you will have a difficuly time running those on the SharePoint server. You still have to enable psremoting and credssp (to avoid double hop), but this allows you to create a module, which can be imported (and set to automatically do so) every time you open powershell. Let me know if you need any help!

# Only need to do this part for initial setup for storage of username and pwd and to turn on the Powershell remoting feature
Enable-PSRemoting
Enable-WSManCredSSP -Role client -DelegateComputer *
# If you want to save credentials for an account (credentials need to be specified using CredSSP Auth). Only need to run once
Read-Host -AsSecureString | ConvertFrom-SecureString | out-file C:\crd-sharepoint.txt 
# Type Password Here 
# You could add this to a logon script to automatically import the sharepoint powershell commands into your session
$pwd = Get-Content C:\crd-sharepoint.txt | ConvertTo-SecureString
$crd = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList "domain\username",$pwd
$session = New-PSSession servername -Authentication CredSSP -Credential $crd  
Invoke-command $session {Add-PSSnapin Microsoft.SharePoint.Powershell}
# Only import the session if you do not want to export it into a module for future use 
Import-pssession -session $session

#This takes a minute or so to spin up so you could save it to disk.     
Export-PSSession -Session $session -OutputModule "SP2010" -CommandName *-SP*

#Import Saved file from disk
Import-Module SP2010

No! you can't do that without SharePoint Installation, or with a client that could be connected to SharePoint Server

In order to run Windows PowerShell remote you have to enable Windows Remote Management on the Server running SharePoint 2010 and the client that you want to run the commands from.

On SharePoint Server

Enable-PSRemoting

Once remoting is enabled on the server you should enable CredSSP.

Enable-WSManCredSSP -Role Server

On the client you should enable remoting and CredSSP

Enable-PSRemoting
Enable-WSManCredSSP -role client -delegatecomputer SPServer.domain.local

When starting a remote session run the following command:

Enter-PSSession -ComputerName SPServer.domain.local `
-Authentication CredSSP -Credential domain\user

To access all the great SharePoint 2010 cmdlets through a remote session you first have to add the SharePoint2010 snap-in

Add-PSSnapin Microsoft.SharePoint.PowerShell

Once the snap-in is added you can run all the SharePoint cmdlets available in SharePoint 2010.

When you’re done you can end the session through the Exit-PSSession cmdlet.

Exit-PSSession
