title: How can I set an SQL Server connection string?
body: <p>I'm developing a simple C# application, and I'd like to know this: When I connect my application to SQL Server on my PC, I know the connection string (server name, password, etc.), but when I connect it to another PC, the SQL Server connection string is different. Is there a common account in SQL Server that comes with a default account that can connect?</p>
  <p>I have heard about the <code>sa</code> account in SQL Server. What is <code>sa</code>?</p>
