- 检查是否有tcp / ip已启用服务器实例

- 检查防火墙

- 使用网络工具（如网络监视器）捕获tcp或ip级别的连接失败

- 此连接字符串在特殊情况 [ ^ ]，你应该使用一般连接字符串语法 [ ^ ]

（PS：从不使用SA将应用程序连接到服务器！您位于域中，甚至可以将AD组添加为SQL Server的用户，因此使用可信连接。 ）

- Check if tcp/ip is enabled for the server instance
- Check firewall
- Use a network tool (like Network Monitor) to catch the connection failure on tcp or ip level
- This connection string is useful in special cases[^], you should use the general connection string syntax[^]
(PS: never use SA to connect an application to the server! You are in a domain and you can add even AD groups as users to SQL server, thus use trusted connection. )
