您好，我在设置 MS SQL 服务器以便远程连接时遇到了问题。我已在 SQL 服务器本身中启用了远程访问，并在配置管理器中启用了 TCP 连接。并且我在 Windows 防火墙中添加了允许端口 1433！但是当我尝试连接时，什么都没有。然后我尝试完全禁用防火墙，突然间我能够连接，所以问题一定出在防火墙上。但是，除了在入站部分添加允许端口 1433 之外，我还必须设置什么，才能让防火墙允许远程访问我的 MS SQL 服务器？

答案1
这是一个愚蠢的问题，但是 SQL Server 实际上是否在监听 1433？
例如，如果它是 SQL Express 的命名实例，它可能正在完全监听不同的端口，您需要在连接字符串中指定该端口，在客户端配置中配置该端口，或者运行 SQL Browser 服务并可用于重定向连接。
SQL Browser 服务监听端口 1434。
答案2
您可以使用提升的命令提示符检查 SQL 服务器真正监听的端口，并且：
netstat -a -b
然后，正如 DoomStone 所说，堵塞连接字符串中的端口。
