Machine Info / Lookup

Modified my get-serial function to get some more stuff. Added cmdlet bindings and info for get-help

function Get-SystemInfo




       [parameter(Mandatory = $true)]

       [string] $ComputerName=$(throw '$ComputerName is required'),

       [parameter(Mandatory = $true)]

       [System.Management.Automation.PSCredential] $Credential =$(Get-Credential)    )

   Get information about the specified machine


   Get information about the specified machine

   Pulls data from the BIOS and Active Directory

.PARAMETER Credential

   Specify a Credential variable $cred

   $cred = get-credential

.PARAMETER ComputerName

   Specify the machine you want to query for information.


   Get-SystemInfo -ComputerName server01 -Credential $cred

  Very nice script by Don Jones

You can pipeline data into this script.
