HTTP Error 500.19 Internal Server Error Solution

Another problem encountered during. Net development under WIN7: HTTP Error 500.19-Internal Server Error. The requested page cannot be accessed because the configuration data on this page is invalid.

The night before, I found that WIN7 prompted me to use pirated products. The black desktop made people uncomfortable. So I found an activation software from the Internet, the system cannot be started. After the USB flash drive is started, it is found that the system folder has not been deleted. I had no choice but to reinstall the flagship version again. As a result, after installing. net, I encountered a problem accessing the page:

Detailed error information module IIS Web Core

Notification BeginRequest

The handler has not been determined

Error code 0x80070021

Configuration error cannot be used in this path. This situation occurs if this section is locked at the parent level. The lock is set by default (overrideModeDefault = "Deny"), or is explicitly set by the position that contains overrideMode = "Deny" or the old allowOverride = "false.

Configuration Source

219: <add name = "ScriptModule" preCondition = "managedHandler" type = "System. web. handlers. scriptModule, System. web. extensions, Version = 3.5.0.0, Culture = neutral, PublicKeyToken = 31BF3856AD364E35 "/> </modules>

220:

221: <remove name = "WebServiceHandlerFactory-Integrated"/>

Solution:

<! -- [Endif] -->

Control Panel --> Programs and functions --> enable or disable windows functions --> roles

If "web Server (IIS)" is not installed yet, select "add ".

If it is already installed, select "web Server (IIS)" --> Add role service.

Select "Application Development (installed)" --> "ASP. NET ".

Configuration error: you cannot use this configuration section in this path. This situation occurs if this section is locked at the parent level. The lock is set by default (overrideModeDefault = "Deny"), or is explicitly set by the position that contains overrideMode = "Deny" or the old allowOverride = "false.

This error occurs because IIS 7 adopts a safer web. config Management Mechanism. By default, the configuration items are locked and cannot be changed. To cancel the lock, run the command line % windir % \ system32 \ inetsrv \ appcmd unlock config-section: system. webServer/handlers. Handlers indicates the node name displayed in the red letter in the error message.

If modules is also locked, run % windir % \ system32 \ inetsrv \ appcmd unlock config-section: system. webServer/modules.

In addition, if you are a friend of Asp.net, remember to check Asp.net when installing IIS7. This option is not selected by default, and a similar error message will appear.
