SQL Server Not Connectig来自另一个系统 [英] SQL Server Not Connectig from another system

问题描述

我的系统已通过无线网络连接。我想从其他系统访问数据库，如何编写连接字符串。

请帮助我... < br $>




建立与SQL Server的连接时发生网络相关或特定于实例的错误。服务器未找到或无法访问。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。 （提供商：TCP提供商，错误：0 - 连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立的连接失败，因为连接的主机未能响应。）



我正面临这个错误...

My system has been connected by the wireless network.I want access database from another system, how to write the connection string.
Please Help me ...


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. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

I am facing this error...

<connectionStrings >
   <add name="myConnectionString" connectionString="Server=192.168.11.4,1433;Database=Employee;User ID=sa;Password=12345;Trusted_Connection=False;" providerName="System.Data.SqlClient"/>
 </connectionStrings>

推荐答案

使用IP地址






Sqlserver中的

use IP Address



in Sqlserver

您是如何安装SQL Server数据库的？检查安装时是否使用了混合模式身份验证。在混合模式身份验证中，使用sa作为用户名并提供所需的密码。



连接字符串为

How did you installed your SQL Server database? Check whether you have used Mixed Mode Authentication while installation. In mixed mode authentication use 'sa' as User Name and give your desired password.

Connection string for this would be

<configuration>
  <connectionStrings>
    <add name="conn" connectionString="Server=myServerName\SQLEXPRESS;Database=myDataBase;User Id=myUsername; Password=myPassword;" providerName="System.Data.SqlClient"/>
  </connectionStrings>
</configuration>

还要检查服务器计算机上是否存在可能阻止与数据库连接的任何防火墙设置。

Also check for any firewall setting present on server machine which may prevent connection to your database.
