ASP.NET IIS Web.config [Internal Server Error]

Question

I changed PC / Windows (XP -> 7) so IIS (6 -> 7,5) and trying to move my website

But I can't run my site from this server . . . error :

Error description: Error HTTP 500.19 - Internal Server Error

The requested page is not available because of incorrect configuration data for this page.

Error Details Module IIS Web Core Notice BeginRequest Handler Not yet determined Error 0x80070021 Configuration error This configuration section can not be used in this way. This happens when the section is locked at the parent level. Locking is either by default (overrideModeDefault = "Deny"), or installed directly by the tag location with overrideMode = "Deny" or inherited property allowOverride = "false". The configuration file \ \? \ D: \ Projects \ Flow WEB \ Sources \ web.config The requested URL-address https: / / 192.168.0.172:443 / Physical Path D: \ Projects \ Flow WEB \ Sources Logon Method Not yet determined Users who have logged on yet to be determined Channel

Configuration

<handlers>    <remove name="WebServiceHandlerFactory-Integrated" /> 

...

my web.config part :

    <modules>         <remove name="ScriptModule" />         <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />     </modules>      <handlers>         <remove name="WebServiceHandlerFactory-Integrated" />         <remove name="ScriptHandlerFactory" />         <remove name="ScriptHandlerFactoryAppServices" />         <remove name="ScriptResource" />         <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />         <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />         <add name="ScriptResource" verb="GET,HEAD" path="ScriptResource.axd" preCondition="integratedMode" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />     </handlers> 

So what's wrong ?

My trying : if I make it -

        <modules allowDefinition="MachineToApplication" overrideModeDefault="Deny">         <remove name="ScriptModule"/>         <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/></modules>     <handlers overrideModeDefault="Deny">         <remove name="WebServiceHandlerFactory-Integrated"/> 

I've got error : Unrecognized attribute "overrideModeDefault"

so I can't add it in configSections because it tells me that It already exist here.

and when I changed IIS to Read/Write (like on picture) Ive got a new error :

    Error description: Error HTTP 404.3 - Not Found The requested page can not be displayed because of the configuration expansion. If the page is a script, add a handler. If you need to download the file, add a MIME. Error Details Module StaticFileModule Notice ExecuteRequestHandler Handler StaticFile Error 0x80070032 The requested URL-address https: / / 192.168.0.172:80 / Default.aspx Physical Path D: \ Projects \ Flow WEB \ Sources \ Default.aspx Anonymous Logon Users who have logged Anonymous The most likely reasons:      * Perhaps there is no comparison handlers. By default, all content is processed by a handler static files.     * Perhaps the component to which the access is not installed.     * Corresponding MIME map is not activated for the website or application. Warning: Do not create a MIME map for content that users should not load - say, for the pages. ASPX or files. Config.     * If ASP.NET is not installed. 

Answer 1

I had a problem with runAllManagedModulesForAllRequests, code 0x80070021 and http error 500.19 and managed to solve it

With command prompt launched as Admnistrator, go to : C:\Windows\Microsoft.NET\Framework64\v4.0.30319>

execute

aspnet_regiis -i

bingo!

Answer 2

Check this in the web.config and change overrideModeDefault from Deny to Allow.

<configSections>   <sectionGroup name="system.webServer">     <section name="handlers" overrideModeDefault="Deny" />      <section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Deny" /> 

You can also manage sections on web server level in your IIS management console from "Feature Delegation".
