myasp.net托管数据库服务器未找到错误

Question

我已将我在vs2010中构建的asp.net网站移动到虚拟主机myasp.net。我试图连接到数据库，但它们的默认连接字符串为：

Data Source=SQL5024.myASP.NET;Initial Catalog=MYDBNAME;User Id=MYUSERNAME;Password=YOUR_DB_PASSWORD 

不起作用。它抛出这个错误：

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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

错误消息的其余部分如下：

[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.

我曾尝试编辑连接字符串包括服务器和端口，如下所示，但它似乎没有不做出改变。

Server=SQL5024.myASP.NET,1433; 

我相信网站上的SQL Server版本是2014年。我已经重新我用本地信的数据库，所以我不明白是什么问题。我错过了与实例有关的事情吗？

事实证明，我需要编辑web.config中的连接字符串以及该页面的后端代码。业余的错误，但也许这可以帮助有类似问题的人。
