asp.net Problems when I access my database
<p>I'm having this problem when I launch my website and try to access my database:</p>

<blockquote>
  <p>Oops. The error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)</p>
</blockquote>

<p>I have a database and I'm connecting to it(Part of the code I used is): </p>

<pre><code> System.Data.SqlClient.SqlConnection con;
            con = new System.Data.SqlClient.SqlConnection();
            con.ConnectionString = "Data Source=.\\SQLEXPRESS; AttachDbFilename=C:\\inetpub\\poject\\App_Data\\data.mdf; Integrated Security = true; Connect Timeout = 30; User Instance = True";
</code></pre>

<p>Any help would be greatly appreciated?</p>
