title: SQL Server Windows authentication untrusted domain
body: <p>I have a question: I have to connect to a SQL Server using Windows authentication. When I try to login from SSMS, all works well, but when I try to login from a .NET app using VS2017, I get this error:</p>
  
  <blockquote>
    <p>Login Failed. The Login is From an Untrusted Domain and Cannot be Used with Windows Authentication</p>
  </blockquote>
  
  <p>The server is not on my computer.</p>
  
  <p>The same error appears if I want to use the same connection string from SISS package.</p>
  
  <p>What might be the issue?</p>
