Sql server 无法连接到SQL Server Management Studio

我正在尝试连接到SQL Server Management Studio。我的团队使用相同的细节，并且能够连接。我是这个队的新手。 有人能帮我接通吗

编辑：事实证明，我无权更改防火墙设置等。我仔细检查了前辈，他们告诉我不需要更改这些设置。还有别的办法吗？一定出了什么问题

编辑：---这是我在连接时得到的弹出窗口

---其他一些细节

我得到以下技术细节--

非常感谢

检查数据库服务器是否正在运行&如果正在运行，请检查防火墙。您必须在1433中添加一个例外，以允许通过网络进行访问。并确保在Sql Server配置管理器上启用了TCP/IP

上面的问题很老，但我今天遇到了类似的问题。我可以在本地连接到SQL，但无法从域内和域外连接

SQL Server必须连接到具有“打开文件和打印机共享”的配置文件

控制面板\网络和互联网\网络和共享中心

或者，如果您试图从公共网络连接，则必须在公共配置文件中连接

---

请尝试通过将其网络连接到公用网络或更新“打开”按钮来更新此设置。。用于共享。

此数据库是否托管在internet上？如果您托管在VPS上，请检查服务器是否正在运行/防火墙..服务器正在运行！！！！我不能做上述改变。此外，有人告诉我，我甚至不需要它们。任何其他输入？@Kum-希望您通过internet访问，检查服务器是否需要VPN连接？是的，通过internet访问。我的VPN连接已启动并正在运行..有大量SQl Server连接疑难解答指南。按开始/运行并键入CMD。键入

PING

是否有响应？如果失败，请将“SQl Server连接疑难解答”键入google并遵循其中的一些指南
