 +====== Powershell get AD info ======
 +The system requirements for Exchange Server 2013 include the following for Active Directory:
  
 +  * Forest and domain functional level of Windows Server 2003 or higher (up to Windows Server 2012 R2 is supported with Exchange Server 2013 SP1 or later)
 +  * Schema Master running Windows Server 2003 SP2 or later
 +  * At least one global catalog server in each Active Directory site where Exchange 2013 will be installed that runs Windows Server 2003 SP2 or higher
 +Using PowerShell we can retrieve all of this information quickly.
 +
 +Here is a script that breaks a whole lot of PowerShell “rules” but gets the job done. 
 +
 +The script requires the ActiveDirectory PowerShell module, and in a multi-domain forest should be run in the forest root domain with an admin account that can access each domain.
 +<code powershell Get-ADInfo.ps1>
 +<#
 +.SYNOPSIS
 +Get-ADInfo.ps1 - PowerShell script to collect Active Directory information
 +.DESCRIPTION 
 +This PowerShell Script collects some basic information about an Active Directory
 +environment that is useful for verifying the pre-requisites for an Exchange
 +Server deployment or upgrade.
 +.OUTPUTS
 +Results are output to the console and to a HTML file.
 +.EXAMPLE
 +.\Get-ADInfo.ps1
 +Runs the script and generates the output.
