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.

Cause：驗證檢視狀態MAC失敗，如果此應用程式由網路場或群集承載，請確保<machineKey>配置指定了相同的validationKey和驗證演算法。在叢集中不能使用自動產生的machineKey。【在一個 Web 服務器場中每個用戶端請求可以在每次回傳轉到另一台電腦。由於這種行為的不能使 validationKey 屬性設定為 自動產生 Machine.config 檔案中。而是，您必須為一個由 Web 場上的所有電腦共用的固定字串設定 validationKey 屬性的值。】

Solution：在進行處理的Asp頁面中的Page標籤處 加入 enableViewStateMac="false"

Authorization-->Cannot verify access to path(D:\......)

The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that <domain>\<computer_name>$ has Read access to the physical path. Then test these settings again.
