title: SQL Server named instance remote connections without port
body: <p>I have a named instance of SQL Server Express that I want to make it visible on the network. I was able to do it, but other machines can only connect to it specifying the port number, even though it is the default port.</p>
  
  <p>For example, other machines can connect to mine using (1433 is the default port for SQL Server):</p>
  
  <pre><code>&lt;hostname&gt;\&lt;instancename&gt;,1433
  </code></pre>
  
  <p>But other machines can't connect without using the port:</p>
  
  <pre><code>&lt;hostname&gt;\&lt;instancename&gt;
  </code></pre>
  
  <p>I checked the Firewall (other people can connect specifying the door), and SQL Server Browser is running (I don't fully understand but I read that it make some difference).</p>
  
  <p>Any tips? Thanks.</p>
