Stop bad handler mappings from re-appearing - asp.net

I'm on Windows 10 running an ASP.Net web app locally in IIS Express. Initially when I was trying to serve my app on localhost I introduced some bad handler mappings in my IIS Express options for the app. I figured out I didn't have IIS ASP.Net installed as part of IIS and fixed that. Then I removed the bad mappings and everything works. But every time I restart my app in IIS the bad mappings re-appear, and I have to remove them again. How do I permanently delete or remove these bad mappings? Thanks in advance for any replies.

I think I figured it out. I added lines to remove the bad handlers in my Web.cong in the system.webServer section ( the Web.config in my projects root folder). The problem was happing everytime I published to the local server. Seems intorducing these lines replaces the Web.config in the app's root folder for the server. Adding these lines seems to fix the problem. Here's the lines I added:
<handlers>
<remove name="Start Module" />
<remove name="Start" />
</handlers>

Simple ASP.NET Razor page on local IIS 8.5 - 500.19 0x8007000d error

I've built sample Razor webpage that works perfectly fine and I decided to deploy it on local IIS enabled on Windows 8.1. (IIS 8.5).
I used the publish feature through the file system that copied relevant files to Inetpub subfolder.
When I try to access the webpage I get this error:
The requested page cannot be accessed because the related configuration data for the page is invalid.
Error Code: 0x8007000d
Config Error:
Config File: (correct path)
The webconfig is suspiciously short but given simplicity of the page - perhaps long enough?
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\myapp.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
</system.webServer>
</configuration>
I made pretty thorough search of similar issues here and other google-returned materials and overall nothing helped.
I'm pretty sure all relevant components that I could install for IIS I have installed already.
All configuration files are correctly formed.
The security is fine - I can play with webconfig content and get different error a bit which indicate IIS can access the config file.
The only thing that surprises me is that sometimes when I access various config icons on IIS for the page I get error like this:
i.e. for .NET Profile:
There was error while performing this operation.
Details: (nothing written here)
Filename: \?\C:\inetpub\wwwroot\mypagefolder\web.config
Error: (nothing written here)
Is my web.config missing some sections?
EDIT: I also dropped the published application on some other IIS server that is used for other applications and the result is the same which make me inclined to believe s.t. is either wrong with the application publish process or s.t. is very weird
Looking at your web.config, it is found that you are trying to deploying ASP.NET Core website. It requires
.NET Core Hosting Bundle installed on the hosting server
Application Pool .NET CLR version set to "No Managed Code"
Ensure that the Application Pool Identity user has read permissions on the published folder.
For details check:
https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/?view=aspnetcore-2.0
First thing I suggest is to check is the .NET CLR version of your application pool and also check the AppPool Identity has read permissions on the published folder
I had the same issue in Windows 2012 Server. Although I had the SDK 2.1 installed, it only worked when I installed Runtime & Hosting Bundle.
https://www.microsoft.com/net/download/dotnet-core/2.1
It's important to mention that, in order to see this option, I had to click on "Can't find the file you want? Find more in .NET Core 2.1 downloads.".

Aurelia does not load on azure, due to HttpPlatformHandler?

I'm using ASP.NET Core RC1 as server to host my Aurelia app. My app was working just fine but the last couple of weeks something changed so that the app does no longer load when hosted on Azure. I'm not sure if it is something I changed or if it's a change on the Azure side but I'm leaning towards the latter.
I've narrowed down the problem quite a bit. The app runs fine locally, with ASP.NET Core Kestrel server and also other servers (e.g. webpack-dev-server). I have continuous deployment setup from Visual Studio Team Services to an Azure Website. The app is published and a web.config is automatically created in my wwwroot:
<configuration>
<system.webServer>
<handlers>
<add name="httpplatformhandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified" />
</handlers>
<httpPlatform processPath="%home%\site\approot\web.cmd" arguments="" stdoutLogEnabled="true" stdoutLogFile="\\?\%home%\LogFiles\stdout.log"></httpPlatform>
</system.webServer>
</configuration>
Nothing happens when I navigate to my site, e.g. http://demo.azurewebsites.net/. When looking at the console I get a 404. Once I actually got this error but I can't seem to bring it back: 502 - Web server received an invalid response while acting as a gateway or proxy server
I have index.html set as default document but it is not loading. If I enter it explicitly, the app works: http://demo.azurewebsites.net/index.html
If I remove the httpplatformhandler from the web.config, then it works as expected (index.html is loaded automatically). The same happens when I remove the web.config entirely. In these cases the MVC 6 WebAPI behind the scenes does not work at all. I assume that's just logical since I remove the platform handler.
So, why is this httpplatformhandler added? Is it necessary? Why is it created? Is there some setting in the Azure portal that I can adjust to prevent this handler to be configured like this?
I also found this link that seems to suggest that things are changing and that this httpplatformhandler is about to be replaced: Closer Look: Hosting ASP.NET Core on Azure App Service
I'm out on deep water here and any and all help is appreciated.
To get default document support with the static file server middleware you need to use app.UseFileServer() instead of app.UseStaticFiles()

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:
Install ASP.NET by calling aspnet_regiis -i
Set my application to use different application pool (ASP.NET v4.0, .NET v4, etc)
ApplicationHost.config file is still using default from Windows 7.
This is part of my Web.Config
<system.webServer>
<section name="handlers" overrideModeDefault="Allow" />
<section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Allow" />
<validation validateIntegratedModeConfiguration="false" />
<modules runAllManagedModulesForAllRequests="true">

<handlers>
<remove name="UrlRoutingHandler" />

<directoryBrowse enabled="true" />
<defaultDocument>

<add value="Logon.aspx" />
</files>
</defaultDocument>
</system.webServer>
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: https://www.microsoft.com/net/download and it started working right away.
Specific link to download: https://go.microsoft.com/fwlink/?LinkId=817246
Yes, for .net core apps, install dotnet hosting. This worked for me.
And here it is for .net6
And now if you need .net7
Install URL rewriting:
UPDATE - this is now available here (and works with IIS 7-10):
https://www.iis.net/downloads/microsoft/url-rewrite
Ensure you have the following set to 'Allowed' for your IIS server:
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
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
https://download.visualstudio.microsoft.com/download/pr/5bed16f2-fd1a-4027-bee3-3d6a1b5844cc/dd22ca2820fadb57fd5378e1763d27cd/dotnet-hosting-3.1.4-win.exe
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

A repair of the DotNetCore hosting bundle did the trick for me. :/
Installing ASP.NET Core Runtime Hosting Bundle solved the issue for me. Source: 500.19 Internal Server Error (0x8007000d)
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="/" />
</applicationInitialization>
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 :)
I turn on .Net Framework 3.5 and 4.5 Advance Service in Control Panel->Programs and Features->Turn Windows features on or off.it work for me.
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
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.
I have the same problem when I was trying to publish asp.net core 5.0 web app on my local IIS and the solution was to add the following inside System.webserver tag in my web.config file
<applicationInitialization doAppInitAfterRestart="true">
<add initializationPage="/" />
</applicationInitialization>
Reinstalling ASP.NET Core Runtime - Windows Hosting Bundle Installer made the trick for me... I belive the "ASP.NET Core Module" was missing.
For me I had a web.config file in one my root folders, this config file was for the live server so removing it allowed the site to run on the dev server.
So check for any web.config files in folders too.
In my case, i have installed dotnet hosting but error change to HTTP Error 503. The service is unavailable, but after install windows update KB2999226 and dotnet sdk, its work!
follow the procedure chronologically or it might fail due to missing or errors in redirecting.
install Runtime bundle e.g.. dotnet-sdk-7.0....
2.turn asp services on and internet services"Turn Windows features on or off" to enable IIS
3.install web hosting bundle iis 7.0 e.g dotnet-hosting-7.0.2...
this worked for me
For me, it was all about setting up my web server to use the latest-and-greatest tech to support my ASP.NET 5 application!
The following URL gave me all the tips I needed:

403 forbidden after publishing asp.net MVC

I know this has been answered a few times but none of the solutions worked for me. I published my ASP.NET MVC 3 application (It was just the internet template without any changes to it) to see if I could get it to work publically. However, when I visit the site it shows up with a 403 error. Coming from a php/linux background, I'm confused and have no clue where to look. I've only been learning .NET for about 8-9 months and everything I've been testing on before was on the local development server through VS2010. It almost appears like the server doesnt know it should be an MVC application or I have to change my routing.
Anyway, I checked to make sure that the server setting is .NET 4. Any help would be greatly appreciated.
ALSO, It's a shared hosting environment using arvixe.
For me this did the trick (Original Answer by Mmerrell at Getting 404.0 error for ASP.NET MVC 3 app on IIS 7.0 / Windows Server 2008 )
You actually just reminded me that I needed to fix this issue in an
enviroment here. If your situation is the same as mine then it's a
simple fix.
Just add the following to your web config:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
Make sure your have choosen the "ASP.Net 4.0" App-Pool and not the App-Pool created for your application.
Make sure your App Pool uses the "ApplicationPoolIdentity" and NOT NetworkService. Remove the NetworkService permission from your root folder. You dont need it. IIS has an built-in identity (IIS_IUSRS).
403 is a forbidden error. Try checking the NTFS permissions of the folder where you deployed, ensure the Network Service user has read permission
Additionally, check the Authentication and Authorization mechanism in the IIS application:
Edited:
.Net Authorization rules
I had this same issue after publishing an MVC 4 WebSite to a remote server using FTP Publishing. What ended up working for me was after publishing through Visual Studio, log onto IIS on the remote server, locate the published directory -> right click -> Convert to Application.
Not sure if there is a way to specify this in the web.config/properties, if you don't have access to the server?
1- verify that your application is running under .NET 4.0 (you did so)
2- check with the hosting company that it supports the MVC 3 framework on their hosting plan.
3- (works) Bin-Deploy your MVC run-time libraries so you may overcome any requirements on the server.
More bout bin-deploy your ASP.NET MVC can be found here: http://haacked.com/archive/2011/05/25/bin-deploying-asp-net-mvc-3.aspx
4- check that "Network Service" has proper access rights to your folder. it basically should have "Read" permission.
Don't forget about aspnet_regiis.exe -ir.
<handlers>
<add name="rewrite" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv4.0,bitness32" />
</handlers>
Ask your hosting provider to add this handlers into webconfig
Try changing the Managed Pipeline Mode of the Application Pool to 'Classic' instead of 'Integrated'.
Whilst it may not be the final result that you're after (there can be real advantages in using Integrated mode), at least it will point you in the right direction... if it works.

HTTP Handler doesn't hitted, while it run over cloud, when request needs to be redirected to another Server from IIS?

My Asp.net application is hosted over Azure Cloud,
In that application I do have a Java Chat control, which has its server on Linux,
now I have created a HTTPHandler to redirect that chat request to the Linux server, but some how it doesn't work over the Cloud environment (though it works very well on web environment)
it shows the below error
Microsoft Visual Studio
Windows Azure Tools for Microsoft Visual Studio
There was an error attaching the debugger to the IIS worker process for URL 'http://127.255.0.0:82/' for role instance 'deployment16(315).Cloud.AnotherHttpHandler_IN_0'. Unable to start debugging on the web server. See help for common configuration errors. Running the web page outside of the debugger may provide further information.
Make sure the server is operating correctly. Verify there are no syntax errors in web.config by doing a Debug.Start Without Debugging. You may also want to refer to the ASP.NET and ATL Server debugging topic in the online documentation.
I have even put the Handler under System.webServer as well in the web.config file, see below code
<system.web>
<httpHandlers>
<add verb="*" path="http-bind/*"
type="HelloWorldHandler"/>
</httpHandlers>
</system.web>
<system.webServer>
<handlers>
<add verb="*" path="http-bind/*" name="HelloWorldHandler" type="HelloWorldHandler"/>
</handlers>
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
I don't know what restricts it over the cloud environment.
Please take a look at this question to see how to configure httpHandlers for running in Azure.
Most importantly - remove the httpHandlers section under the system.web and leave only handlers under system.webServer. Then add also the resourceType="Unspecified" attribute to the handler declaration. This should solve your issue.
I too had same problem.
I fixed it in following way .
The Problem was my machine is 32 bit and the azure server is 64 bit.
In Order to solve the problem i only changed Enable 32 bit option in
the advance setting of application pool. And the Original code worked
out fine.
i got this help from this Link
