問題與我的mvc4應用程序連接字符串

Question

我幾天前發佈了我的網站，但它似乎是我的連接字符串的問題。我嘗試多次改變它，並得到相同的結果，並花了很多時間。

我實際的ConnectionString是：

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

從我提供一些數據：

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 

的堆棧跟蹤，你可以看到如下內容：

[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.

謝謝你們！

編輯：我開始認爲這不是連接字符串問題，而是一個服務器配置。

嘗試以下方法來代替，看看它是否

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