This script will copy files from one server (server_a) to another (server_b) using robocopy and a list of folders.
First we check to see if the folder being copied to the destination server (server_b) exists on the host server (server_a), 
if not  the folder is created and  the ACL are modified, Then the users AD profile is updated with the new home drive and specified drive letter.  

If the folder already exists on server_a robocopy copies all the contents including file perms and sends a log everything
