无法仅从计算机上的应用程序连接到 SQL 服务器

我有一个非常简单的应用程序：

    static void Main(string[] args)
    {
        try
        {
            var connection = new SqlConnection("Data Source=SQL;Initial Catalog=MyDatabase;Integrated Security=True");
            connection.Open();
            Console.WriteLine(connection.State.ToString());
        }
        catch(Exception e)
        {
            Console.WriteLine(e.Message);
        }
        Console.ReadLine();
    }

运行应用程序给我一个例外

建立与 SQL Server 的连接时发生与网络相关或特定于实例的错误。找不到服务器或无法访问服务器。验证实例名称是否正确，以及 SQL Server 是否配置为允许远程连接。（提供程序：命名管道提供程序，错误：40 - 无法打开与 SQL Server 的连接）

内部异常：

访问被拒绝

这个程序适用于其他人的机器。在我的机器上，在 c# 交互式作品中键入以下内容：

 Microsoft (R) Roslyn C# Compiler version 1.2.20906.1 
Loading context from 'CSharpInteractive.rsp'.
Type "#help" for more information.
  using System.Data.SqlClient;
  var connection = new SqlConnection("Data Source=SQL;Initial Catalog=MyDatabase;Integrated Security=True");
  connection.Open();
  connection.State
Open

此外，如果连接是从我的计算机上运行的 WCF 服务建立的，则连接似乎可以正常工作。我能够使用 SQL Server Management Studio 和 Visual Studio Server Explorer 从我的计算机进行连接

我的第一个想法是我的机器上的防火墙问题。不过我已经禁用了防火墙，但我仍然遇到问题。
