IIS 8 asp.net mvc HTTP 錯誤 500.19

您好，我剛剛為我的 asp.net mvc 框架移動了伺服器。但現在我收到以下錯誤消息，老實說，我現在知道出了什麼問題嗎？

模組 IIS Web 核心

通知開始請求

處理程序尚未確定

錯誤程式碼 0x80070021

配置錯誤 此配置部分不能用於此路徑。當該部分鎖定在父級別時會發生這種情況。鎖定是預設情況下 (overrideModeDefault=“Deny”) 或由具有 overrideMode=“Deny” 或舊 allowOverride=“false” 的位置標記顯式設置的。

我們在全新的伺服器上遇到了同樣的錯誤。

原因不是儲存在 中的預設 IIS 安全策略，applicationHost.config正如另一個答案所建議的那樣（儘管我們檢查過）。原因是我們安裝的 IIS 不支持 ASP.NET（一個 ASP.NET 4.5 角色）！

當我們安裝缺少的對 ASP.NET 的支持時，我們的應用程序剛剛啟動，配置沒有任何變化。

結論：

如果您收到此錯誤，請仔細檢查您是否已隨 IIS 一起安裝了 ASP.NET 角色。

在 Windows Server 中安裝 ASP.NET 角色：

1. 打開添加角色和功能嚮導
2. 檢查 ASP.NET$$ your_version $$進入Web Server (IIS)-> Web Server->Application Development

在 Windows 客戶端中安裝 ASP.NET 角色：

1. 打開打開或關閉 Windows 功能嚮導
2. 檢查 ASP.NET$$ your_version $$進入Internet Information Services-> World Wide Web Services->Application Development Features
