系統找不到Windows Server 2012中指定的文件

Question

我檢查了很多參考站點來解決此問題，但沒有人給出正確的解決方案。 我將應用程序托管在Windows Server 2008/2012上，但無法正常工作。

實際上，它在本地系統上運行良好，但是發布后，我將該應用程序托管在服務器上，則無法正常工作。

以下是錯誤的詳細信息。

該系統找不到指定的文件。

說明：在執行當前Web請求期間，發生了未處理的異常enter code here 。 請查看堆棧跟蹤，以獲取有關錯誤及其在代碼中起源的更多信息。

如您在堆棧跟蹤中所見。 它告訴你問題所在。 最有可能的是，您與數據庫的連接已斷開，或者您無法連接數據庫服務器。

“建立與SQL Server的連接時發生了與網絡相關或特定於實例的錯誤。找不到服務器或無法訪問該服務器。請驗證實例名稱正確並且已將SQL Server配置為允許遠程連接。（提供者： SQL網絡接口，錯誤：52-無法找到本地數據庫運行時安裝。請驗證是否正確安裝了SQL Server Express並啟用了本地數據庫運行時功能。）]“

此外，您需要研究：

1]從Web服務器到數據庫服務器的Firewall settings
2]連接字符串錯誤
3]啟用適當的協議管道/ tcp-ip
4]檢查SQL Server service運行
