在Azure上託管的Web應用程序訪問本地SQL數據庫

Question

我試圖從託管在Azure中的服務訪問公司內部存在的SQL數據庫。 這是我曾嘗試：

1. 創建的本地服務器上的MS SQL數據庫
2. 創建示例Web應用程序（Windows Azure雲服務）
3. 修改Web.config文件有正確的SQL連接串
4. 使用激活令牌從Azure管理激活Web門戶的作用
5. 安裝本地端點在本地服務器上
6. 發佈的Web應用程序天青
7. 使用Web角色和OCAL端點
8. 啓動試圖從數據庫中讀取記錄的應用
9. 創建端點組。

提示以下錯誤：試圖使用Azure的從數據庫中讀取記錄：

System.Data.SqlClient.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.

請幫助。

Trusted_Connection必須爲false。您無法從Azure進行Windows身份驗證。
