ASP.NET: HTTP Error 500.19 – Internal Server Error 0x8007000d


I am replicating web application deployment and found several issues related to HTTP Error 500.19. My machine is running Windows 7 while the working development is using Windows 8. We're developing our Web Application using Visual Studio 2010.

First, I got error code 0x80070021, similar as posted here. I update my web.config according to the accepted answer and then I got following error code (which is similar as posted here).

HTTP Error 500.19 - Internal Server Error
Error Code 0x8007000d
Config Source -1: 0:

I have read the symptoms definition in Microsoft support page and cause of the error is:

This problem occurs because the ApplicationHost.config file or the Web.config file contains a malformed XML element.

and the solution is

Delete the malformed XML element from the ApplicationHost.config file or from the Web.config file.

However, the web.config that I used is working perfectly in the original development environment.

Here is what I have checked and tried so far:

  1. Install ASP.NET by calling aspnet_regiis -i
  2. Set my application to use different application pool (ASP.NET v4.0, .NET v4, etc)
  3. ApplicationHost.config file is still using default from Windows 7.

This is part of my Web.Config

    <section name="handlers" overrideModeDefault="Allow" /> 
    <section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Allow" />
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true">
        <remove name="UrlRoutingHandler" />
        <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <urlCompression doStaticCompression="true" doDynamicCompression="false"></urlCompression>
    <directoryBrowse enabled="true" />
            <add value="Logon.aspx" />

I have read similar/duplicates/closed posts (around 13) posts in stackoverflow, tried all except the answer related to Ajax (is it related) and still have no clue on what the error is.

Does anyone one how to fix this error? (And if possible, a comprehensive lists of things need to be checked so we can reduce similar posts like this.) I am ready to provide more details.

Error 0x8007000d means URL rewriting module (referenced in web.config) is missing or proper version is not installed.

Just install URL rewriting module via web platform installer.

I recommend to check all dependencies from web.config and install them.

When trying to set up a .NET Core 1.0 website I got this error, and tried everything else I could find with no luck, including checking the web.config file, IIS_IUSRS permissions, IIS URL rewrite module, etc. In the end, I installed DotNetCore.1.0.0-WindowsHosting.exe from this page: and it started working right away.

In my case, because I had reinstalled iis, I needed to register iis with dot net 4 using this command:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

Install URL rewriting:

UPDATE - this is now available here (and works with IIS 7-10):

Ensure you have the following set to 'Allowed' for your IIS server:

In my case (.Net Core Web API) for this issue HTTP Error 500.19 – Internal Server Error 0x8007000d

First download dotnet-hosting-3.0.0-preview5-19227-01-win (.Net Core 3) or dotnetcore 2 hasting windows

Any .net core 3.1 application either angular or mvc application would need this.

Second install it as Administrator Open cmd as administrator, type iisreset, press enter

So refresh your localhost app

Kind of late to the party here, but I have just been struggling with the exact same issue (symptoms) and cursing the lack of error detail reporting. It worked fine on IIS 8+ machines but Win 7 got these INSTANT HTTP 500.19 errors. For me it was as silly as having an unsupported configuration element in the config file:

 <applicationInitialization doAppInitAfterRestart="true">
  <add initializationPage="/" />

So while running old web.config files worked fine, I just diffed them and started chopping away at new blocks until I got the page to start loading. Had I seen this as an answer I would have gone this route immediately as I knew none of the popular solutions were relevant. So there you go :)

A repair of the DotNetCore hosting bundle did the trick for me. :/

I turn on .Net Framework 3.5 and 4.5 Advance Service in Control Panel->Programs and Features->Turn Windows features on or work for me.

Installing ASP.NET Core Runtime Hosting Bundle solved the issue for me. Source: 500.19 Internal Server Error (0x8007000d)

Problem solved. Here are the steps that I tried:

  • Enable the 32-bit application in IIS -> Application pool -> Advanced settings
  • Copy System.EnterpriseServices.dll and System.EnterpriseServices.Wrapper.dll from C:\Windows\Microsoft.NET\Framework\v2.0.50727 to the application bin folder
  • Do comments/uncomments to sections on the web.config and found that problem related to the referenced DLL.

The config that I commented the previous one that I added:

<section name="handlers" overrideModeDefault="Allow" /> 
<section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Allow"/>
  • Add the required FasterFlect.DLL used by Combres.DLL v2.1.0.0 to the application bin folder (shall download the full zip from Combres codeplex, because the required fasterflect DLL V2.0.3732.24338 cannot be found in fasterflect codeplex) and other DLLs. For convinience, use the full Combres.DLL (1,3MB)
  • Check that the DLL versions and public key tokens are configured correctly in web.config using tool, e.g. .NET Reflector

I understand that this error can occur because of many different reasons. In my case it was because I uninstalled WSUS service from Server Roles and the whole IIS went down. After doing a bit of research I found that uninstalling WSUS removes a few dlls which are used to do http compression. Since those dlls were missing and the IIS was still looking for them I did a reset using the following command in CMD:

appcmd set config -section:system.webServer/httpCompression /-[name='xpress']

Bingo! The problem is sorted now. Dont forget to run it as an administrator. You might also need to do "iisreset" as well. Just in case.

Hope it helps others. Cheers

Yes, for .net core apps, install dotnet hosting. This worked for me.

dotnet hosting installer exe

I had this problem with a brand new web service. Solved it by adding read-only access for Everyone on Properties->Security for the folder that the service was in.

I had the exact same error. It turned out that it was something was caused by something completely, though. It was missing write permissions in a cache folder. But IIS reported error 0x8007000d which is wildly confusing.
