SocketException（0x274c）通過ASP.net，.net 4.0，IIS 7

Question

我在IIS 7上部署了我的網站，編譯它時沒有錯誤，但是當在遠程IIS 7上部署應用程序時，檢查頁面索引頁是好的，但錯誤消息顯示在下面的頁面。

的問題是，當用戶開始搜索信息（這是一個XML文件請求），頁面顯示一些錯誤，如：

Server Error in '/' Application. 

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. xx.xx.xx.xx:xx 

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

我想知道如果這是IIS 7設置的問題，但直到現在我無法修復它。我的服務器環境是.NET 4.0和IIS 7，在Windows 7上。

我不知道如何跟蹤這個錯誤，如果有更多的信息或代碼需要提供，請提醒我，謝謝你的回答。

通過堆棧跟蹤的外觀，您將URL傳遞給XmlDocument.Load函數。如果文件位於本地服務器上並且正在執行的應用程序池可以訪問該文件夾，請嘗試使用Server.MapPath（docs）來獲取文件系統位置，並將其傳遞到XmlDocument.Load。

如果傳遞URL是所需的行爲，請檢查應用程序是否可以實際訪問外部資源（服務器上的代理設置等）。
