# vRA 6.2 Pre-Req Automation Script v1
#==============================================
#----------------------------------------------
#==================USAGE=======================
# For Windows Server 2008 & 2012
# This script has been created to aid in 
# Configuring the settings for the vRA 6.2
# Pre-Req Checker. This script will set all
# Pre-Req's except for enabling TCP/IP in 
# MS SQL, chich needs to be performed manually
# And the services will need to be restarted.
#----------------------------------------------
#===============REQUIREMENTS===================
# For this script to run successfully be sure:
# 	*To run PowerShell as administrator
#	*To have admin rights on the server
#----------------------------------------------

#=============EDITOR'S NOTE====================
# In order for this script to work on servers that
# have proxied or restricted access to the Internet,
# it is necessary to configure a local source repository
# or else the features and roles requiring .NET 3.5 will fail.
# To do so, configure the variable called $InstallSource
# below making sure to set the path appropriately. In
# this example, the source is provided by mounting the
# installation CD as drive D.
