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>
I followed the accepted answer to this question to try to get my .Net web application to run under a specific set of credentials when debugging locally via the IIS Express server running on my machine, however, I can't seem to get the changes to pick up. Admittedly, I have no idea how to verify what is actually happening, but the behavior I'm seeing leads me to believe that the web app just continues to run under my own Windows credentials. I've stopped the IIS Express processes via System Manager and also restarted my computer, but no dice. Here's what I have in my applicationhost.config file...
<applicationPoolDefaults managedRuntimeLoader="v4.0">
<processModel userName="username" password="a_strong_pwd" />
</applicationPoolDefaults>
Try adding an indentityType="SpecificUser" attribute:
<applicationPoolDefaults managedRuntimeLoader="v4.0">
<processModel indentityType="SpecificUser" userName="someName" password="a_strong_pwd" />
</applicationPoolDefaults>
The settings are detailed in: https://msdn.microsoft.com/en-us/library/ms689446(v=vs.90).aspx
What fixed things for me was editing %userprofile%\documents\IISExpress\config\applicationhost.config. Apparently, it overrides the applicationhost.config that Visual Studio points to.
Running on Windows 8, I have enabled the Application Initialization feature of IIS from the Windows Features install options for IIS.
I'm attempting to get an ASP.NET Web app to start up immediately and fire into Application_Start when the Application Pool is restarted. I've followed the instructions from this tutorial, but after setting the values in the ApplicationHost.config, and web.config I see nothing is firing.
Here's what I've set (which seems to match what the article suggests):
<applicationPools>
<add name="MPress" autoStart="true"
enable32BitAppOnWin64="true"
startMode="AlwaysRunning">
<processModel identityType="LocalSystem" setProfileEnvironment="true" />
</applicationPools>
<sites>
<site>
<application path="/MPress.Workflow.WebQueueMessageManager"
applicationPool="MPress" preloadEnabled="true">
<virtualDirectory path="/" physicalPath="C:\Projects2010\Clients\MPress\MarvelPress.Workflow.WebQueueMessageManager" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:80:" />
</bindings>
</site>
</sites>
And then in the local web.config I have:
<system.webServer>
<applicationInitialization remapManagedRequestsTo="Startup.htm"
skipManagedModules="true"
doAppInitAfterRestart="true">
<add initializationPage="default.aspx" />
</applicationInitialization>
</system.webServer>
Other than the doAppInitAfterRestart flag this matches the settings in the above article exactly except pointing at my virtual app and application pool.
It appears that the Application Pool auto load works - if I stop and restart IIS w3wp I see the application pool show in the task list. But using Process Explorer I can see that the EXE hasn't loaded .NET just sitting there. No .NET Runtime dlls are loaded, so it appears that no request has fired.
What really sucks is that there's no real documentation of section and expected values required for each setting. The doAppInitAfterRestart flag is documented nowhere that I could find. I've also left that out with the same results. I'm also not 100% what the syntax for the URL is. The MSDN article points at "/default.aspx" and I tried that too to no avail.
I also turned on Failed Request Tracing in IIS to see if maybe the fake request fails somehow, but nothing shows up in there. It simply looks like Site Level load is not firing when the application pool restarted.
All of the settings mentioned here are also available through the IIS Admin UI in Windows 8 and everything certainly looks correct.
I'm out of ideas on what else to check or what I might be missing. Any ideas appreciated.
After some more spelunking it turns out that although I had installed the Application Initialization feature using the Windows 8 features, the actual module was not added to the globalModules list.
The following was missing and once added everything started working just fine:
<globalModules>
<add name="ApplicationInitializationModule" image="%windir%\System32\inetsrv\warmup.dll" />
</globalModules>
I faced similar issue but after doing a bit of comparison I found that you need to set Application Pool Managed Pipeline Mode to Integrated. It will not work with Classic Mode
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">
</modules>
<handlers>
<remove name="UrlRoutingHandler" />
<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</handlers>
<urlCompression doStaticCompression="true" doDynamicCompression="false"></urlCompression>
<directoryBrowse enabled="true" />
<defaultDocument>
<files>
<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:

Scenario
I am attempting to auto-start/keep-alive/preload information in my ASP.Net application. The instructions are plain and clear: ASP.Net + IIS 7.5 - Preloading & Auto Starting, but I am having problems with doing so in IIS 7.5 Express. I get a 500.19 error regarding some of the config elements. Below is context and question:
ApplicationHost.config
<!-- Inside the ApplicationPools element we tell the appropriate app pool
to auto start and always run. -->
<add name="Clr4IntegratedAppPool" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated" CLRConfigFile="%IIS_USER_HOME%\config\aspnet.config" autoStart="true" startMode="AlwaysRunning" />
<!-- In the Sites element we first ensure our application is using the correct
app pool. Then we tell it to use the pools auto start functionality, and
point it towards a provider to use. -->
<site name="ED.Web" id="11">
<application path="/" applicationPool="Clr4IntegratedAppPool" serviceAutoStartEnabled="true" serviceAutoStartProvider="Preload-UserReconciliation">
<!-- everything is properly closed -->
<!-- Just before closing the Sites element we declare a provider; it identifies
the class within a particular assembly that should be used for preloading -->
<serviceautostartproviders>
<add name="Preload-UserReconciliation" type="ED.Web.ApplicationPreload, ED.Web" />
</serviceautostartproviders>
</sites>
Error 1
Error 500.19, Unrecognized element 'serviceautostartproviders'
239: <serviceautostartproviders>
240: <add name="Preload-UserReconciliation" type="ED.Web.ApplicationPreload, ED.Web" />
Error 2 [EDIT]
After shutting down IIS Express entirely, and launching the app from VS again, I get a Visual Studio popup: "Unable to launch the IIS Express Web server."
Question
How do I properly setup IIS Express 7.5 to start the pool, and preload the app using my ApplicationPreload : IProcessHostPreloadClient class?
Embarassing...
http://www.iis.net/download/ApplicationInitialization
I completely missed that this was an out-of-band module for IIS 7.5, not base functionality.
It is included in base functionality beginning with IIS 8.0.
The original post I found with this information on it, did not point that out, and when I used the link referenced in question, I completely breezed over the bright yellow box looking only at the code.
