Running PowerShell on MOSS 2007

1. If you are running MOSS 2007 on Windows Server 2003 the you have to download and install PowerShell from https://support.microsoft.com/kb/968930. Windows Server 2008 natively supports PowerShell.
2. Set the Execution Policy to 'RemoteSigned'. You can check it by running 'Get-ExecutionPolicy' cmdlet
   The default execution policy for PowerShell is “Restricted” (commands only, not scripts)     

 # All scripts running locally are allowed
 Set-ExecutionPolicy RemoteSigned

This means downloaded scripts must be signed by a trusted publisher before they can be run.

• Using the Set-ExecutionPolicy Cmdlet      
• How does the RemoteSigned execution policy work?

     3. You need to load the SharePoint assemblies with the following command

 #    Load the SharePoint assemblies
 [Void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")

A bunch of PowerShell scripts are available at https://www.powershell.nu/2009/09/08/moss-2007-script-collection
