I want to upload my own asp.net website on IIS with IIS Manager. But when I do this, I get the following error
HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid
Module IIS Web Core
Handler Not yet determined
Config Error Cannot read configuration file due to insufficient permissions
\\?\C:\Users\Yasso\Documents\Visual Studio 2008\WebSites\WebSite5\web.config
I searched many times for a solution for this error, but none of the solutions solved the error.
I have a problem with my
IUSR account. I can't see this account in the "group or user names" in the properties of the
What is the problem?
Finally, I got the solution for my problem. The ASP.net account did not appear in the IIS manager, because I didn’t check its checkbox in IIS. To do this in Windows 7 follow the steps:
Now, you will see the ASP.net account on the IIS manager and by default you will see the IIS account. Now, you should move your ASP.net website from “my document” to another place where the IIS have permission to access it (i.e. to another partition on your computer). Now, browse your website from the IIS manager and it should work.
Thanks a lot for Jeff Turner for the solution.
The message is saying that your configuration file is corrupt in some way. However it also says that it can't actually access the config file. So I'd ignore the original message about corruption/lack of validity as this is most likely just the effect of not being able to read the file due to a lack of authorization.
The reason it cannot read the config file is because the process running your web app does not have permission to access the file/directory. So you need to give the process running your web app those permissions.
The access rights should be fairly straightforward, i.e. at least Read, and, depending on your app, maybe Write.
Above, you mention IUSR etc. not being in the properties for
web.config. If by that you mean that IUSR is not listed in the security tab of the file then it's a good thing. One doesn't want to give IUSR any kind of permission to web.config. The role IUSR is an anonymous internet user.
The file web.config should only be accessible through your application.
The problem is you haven't said which OS and IIS version you are using so it's difficult to advise which steps to take.
I.e. in IIS 7.5, the error message you're quoting is likely to occur due to your ApplicationPoolIdentity not being assigned the permissions. Your web application belongs to an application pool and so you need to give the permissions to the OS account that your web application's application pool runs under. Often this is something like NetworkService but you may have customized it to run under a purpose made account. Without more info it's difficult to help you.
I was having the same problem, here is the solution that worked for me.
For Visual Studio (VS) developers: As hinted at by Harvey Darvey, Savage, and Snives, your Application Host Configuration may be pointing to the wrong application physical path. Search for virtualDirectory within /.vs/config/applicationhost.config to change the physicalPath if it is incorrect.
Make sure the physicalPath is correct:
You need to assign permissions for IIS_IUSRS on the local machine (but you don't have to assign for IUSR, in fact it will work even if you explicitly deny permissions).
To assign permissions, just right click on the folder and on the security tab make sure to grant the correct permissions, and if the user is not listed then click "ADD", and enter IIS_IUSRS (and make sure that under "domain" the local computer is selected, or enter in the name field YourLocalComputerName\IIS_IUSRS), and then you are good to go.
If you want you can instead of assigning permissions to the IIS_IUSRS group, you can instead assign to the app pool which should in general be "IIS APPPOOL\ app pool name".
Just to chip in, I received the same kind of error and my problem was quite simple: I was missing the .NET Core Hosting Bundle. Once I installed the tool and restarted the server, it was fine.
You can find the manual to host asp.net core on windows here: https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/?view=aspnetcore-2.2
The same thing happened with me , Try checking this by double clicking on the Connection strings on the right pane of IIS 7 when you select a website.
It will give you an error (that there is some problem with web config file), because you have used URL rewrite rules and the respective component is not installed.
Install “Microsoft URL Rewrite Module 2.0 for IIS 7” and this should fix your problem
Nothing here worked for me, I found this command in another SO answer though and it solved my problem. Just start command prompt as an administrator and run this command:
run->cmd run "c:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i"

I do these steps to solve this problem in Windows Server 2012, IIS 8.5. Should work for other versions too.
.NET Extensibility 4.5,
ASP.NET 4.5and both
Management Tools(IIS Management Console and Management Service), Windows
This also happened to me when I had a default document of the same name (like index.aspx) specified in both my web.config file AND my IIS website. I ended up removing the entry from the IIS website and kept the web.config entry like below:
<system.webServer> <defaultDocument> <files> <add value="index.aspx" /> </files> </defaultDocument>...
Sometimes this message has can be missing components in your IIS environment e.g. a particular framework, or an IIS feature like dynamic compression, rather than permissions to web.config.
If this is the case, a solution can be to install and use the Microsoft Platform Installer and install those missing components - you might have to take a stab at what exactly is missing because the error log and message don't tell you.
You need to set permission for your Website folder or copy they to wwwroot folder :) - If set permission, have 2 way: + Right click to Your Website folder + Or right click to Your Website in IIS => select Edit permission and Add a permission (IUSR - default iis user) Good luck ;-)
Install ASP.NET Core module
Download the installer using the following link: https://www.microsoft.com/net/permalink/dotnetcore-current-windows-runtime-bundle-installer
I too had the similar issue and i fixed it by commenting some sections in web.config file.
The project was earlier built and deployed in .Net 2.0. After migrating to .Net 3.5, it started throwing the exception.
If your configuration file contains "<sectionGroup name="system.web.extensions>", comment it and run as this section is already available under Machine.config.
On the IIS 7.5 error page you get click on 'View more Information' at the bottom of the page and in this case it will take you to the following Microsoft link:
The 0x80070005 Error Code seems to be permissions related and following the steps in Resolution 2, Method 2 assigning the correct accounts with permissions on relevant folders should fix it - I spent 3 days looking for a solution until I came across it, worked straight after.
Explore the folder where your website is store and see you will get one extra folder "aspnet_client" delete that folder and it will work for you.
I tried this my problem is solved.
If it works for you please make it as answer so that some body else will also get solution.
I got this bizarre error after specifying values in the
web.config at the following-path
We prefer to control how IIS is configured using
web.config since IIS is a dreadful product and hard to configure using other methods.
The problem was that IIS stamps its authoritay by locking parts of configuration to outside meddlers.
The authentication configuration can be unlocked using the Feature Delegation applet at the IIS Server level, setting Read/Write.
Of course, whereas before we'd have to automate the configuration of IIS auth types, now we have to automate the unlocking. Did I mention IIS is a dreadful product?
In my case I selected application pool with .NET Framework 2.0 and enabled 32-bit application. I had .NET Framework 2.0 application.
After a server crash we had a site start giving the "HTTP 500.19 0x80070005 Error - Cannot read configuration file web.config" error. Normally it would be permissions or the anonymous user configuration, but those were set fine and hadn't changed. Suspecting something got corrupted in the IIS metabase (or in the in %windir%\system32\inetsrv\config\applicationHost.config since IIS7) I was able to get it back up and running by deleting the site in IIS and re-creating it.
Check the Error/HResult Code and follow this guide:
This problem occurs for one of the following reasons:
- You are using IIS 7.0 on a computer that is running Windows Vista. Additionally, you configure the Web site to use UNC Passthrough authentication to access a remote Universal Naming Convention (UNC) share.
The IIS_IUSRS group does not have the appropriate permissions for the ApplicationHost.config file, for the Web.config file, or for the virtual/application directories of IIS.
Do not configure the Web site to use UNC Passthrough authentication to access the remote UNC share. Instead, specify a user account that has the appropriate permissions to access the remote UNC share.
Grant the Read permission to the
IIS_IUSRSgroup for the
ApplicationHost.configfile or for the
So in simple words, you need to:
IIS_IUSRSgroup and confirm.
Install the .NET Core Windows Server Hosting bundle
I was getting this error when running my project from my local machine using visual studio 2017
Not one of these solutions worked for me. At the end of the day, the fix that worked for me was the following:
* Very Easy Solution:
Go to IIS
Select your application from left Pane.
Double click on Directory Browsing in middle Pane.
Now go to right pane and under Action tab, Just click 'ENABLE'
That's all !!
