title: sa user is locked out and login fails with Windows Authentication. Now what?
body: <p>I am logged in to a Windows 7 computer as an admin. I am trying to connect to SQL Server 2012 on the same machine. The SA account is locked out. When I try Windows Authentication, the login fails.</p>
  
  <p>How do I log in now? Is there an external tool to unlock the SA user? I used an external tool to change the SA password. I don't want to reinstall the software.</p>
