TITLE: Connect to Server

ADDITIONAL INFORMATION:

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.

推荐答案

如错误所述，您的应用程序无法与服务器通信。由于您使用了直接IP地址，我会检查以下内容：

- 端口1234是否正确？这不是默认端口（1433）所以它已经过验证了吗？

- 两者之间是否有防火墙？特别是因为使用了非标准端口，需要在防火墙中打开（如果有的话）

- SQL Server服务正常运行？

- 正确的IP地址？ （如果您尝试 ping

As the error states, your application cannot communicate with the server. Since you have used a direct IP address I would check the following things:
- is the port 1234 correct? It''s not the default port (1433) so it''s verified?
- is there a firewall in between? Especially since non-standard port is used, it needs to be opened in the firewall (if present)
- SQL Server service up and running properly?
- correct IP address? (what happens if you try ping

添加/检查防火墙策略已打开端口1433（默认）或特定端口根据您的sql server listner port ..

看看这个： http://msdn.microsoft.com/en-us/library/ms190608%28v=SQL.100%29.aspx [ ^ ]

Add/Check Firewall policy is open for port 1433(Default) or specific port according to your sql server listner port..
