title: Windows user name an password authentication for account not currently logged in
body: <p>I can access the current Windows user, but I want to give an admin the ability to enter an alternate username and password for a different Windows Active Directory Account without having to logoff and log back in. Once the account is authenticated, I need to use it in a connection string to sql server. I know I could do this for a SQL Server login, but this is Windows Authentication only.  </p>
  
  <p>It was installed with ClickOnce. Is there an .exe file on the user's machine?</p>
