title: ASP.NET : Connection String not working IIS - Internal Server Error
body: <p>So I have a WebAPI project with Individual Accounts, and I published it to a folder. </p>
  
  <p>After that, I added a new website in IIS Manager. I created a new connection string with SQL Server Settings:</p>
  
  <ul>
  <li>Server : WINDOWSHOST\WINSQLSERVER</li>
  <li>Database : Database2</li>
  <li>Credentials : Use Windows Integrated Security</li>
  </ul>
  
  <blockquote>
    <p>Server=WINDOWSHOST\WINSQLSERVER;Database=Database2;Intergrated Security=true</p>
  </blockquote>
  
  <p>If I use WINDOWSHOST\WINSQLSERVER and IntergratedSecurity in SQL Server Management Studio, I can log in successfully, but trying to create an account gives me an internal server error</p>
