RE: Regarding MS12-020

Actually, the tool included (which I will post here since it would be quite 
difficult to pull the code from the PDF) mitigates WS03 as well.  
Mathematically, there is a 1 in 4 billion chance someone could establish an RDP 
session, but applicably,  no one ever would.  

Security in depth, and least privilege.  It works :)
