问题与我的mvc4应用程序连接字符串

Question

我几天前发布了我的网站，但它似乎是我的连接字符串的问题。我尝试多次改变它，并得到相同的结果，并花了很多时间。

我实际的ConnectionString是：

<add name="Server" connectionString="user id=xxxx;pwd=xxxx;Data Source=emboole.mssql.somee.com;Initial Catalog=emboole" providerName="System.Data.SqlClient" /> 

从我提供一些数据：

MS SQL Server address: emboole.mssql.somee.com 
Login name: xxxx 
Login password: xxxx 
Connection string: workstation id=emboole.mssql.somee.com;packet size=4096;user id=xxxx;pwd=xxxx;data source=emboole.mssql.somee.com;persist security info=False;initial catalog=emboole 

的堆栈跟踪，你可以看到如下内容：

[Win32Exception (0x80004005): The system cannot find the file specified] 

[SqlException (0x80131904): 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.

谢谢你们！

编辑：我开始认为这不是连接字符串问题，而是一个服务器配置。

尝试以下方法来代替，看看它是否

<add name="Server" connectionString="server=emboole.mssql.somee.com;Database=emboole;Uid=xxxx;Pwd=xxxx;" providerName="System.Data.SqlClient" />
