The requested page cannot be accessed because the related configuration data for the page is invalid - asp.net

I am getting this error when I try to run an ASP.NET application without a web.config file.
The requested page cannot be accessed because the related configuration data for the page is invalid
as I read, we can run .NET applications without web config files, but when I tried it is giving me the error. I am using iis 7 on windows 7 machine.
When I create the application virtual directory inside inetpub/wwwroot it works fine. Why doesn't the other directory location?

One reason could be the version of .NET framework (on IIS or application pool level) is different from the application one.
Another reason could be if there are modules used in your web.config which the current configuration of IIS doesn't recognize. E.g. URL rewrite or other optional modules, which you have to explicitly enable before using.

This can be a reason:
If there is no Web.config file in the
UNC directory, IIS 7.0 uses the rules
that are defined for the parent
directory. For the Web content to be
served in this scenario, the
worker-process identity must have
access to the whole content directory.
Otherwise, the Web request is
rejected.
Details here.

You need to set permission for your Website folder or copy them to wwwroot folder.
If you choose to set permission, there are two ways:
Right click on Your Website folder, or
Right click to Your Website in IIS
Then select Edit permission and Add a permission (IUSR - default iis user)

web.config application pool error after moving to new server

I have the following error after move my website from server to another server
I have already checked iis and make sure the app has an application pool and it points to the correct file path
here is a screenshot of my application pool
I even tried to add virtual directory and add application and still not working
Check siteMapFile attribute of sitemap
The possible reason behind the issue is:
When you create a new web application using visual studio.net, it automatically creates the virtual directory and configures it as an application. However, if you manually create the virtual directory and it is not configured as an application, then you will not be able to browse the application and may get the above error. The debug information you get as mentioned above, is applicable to this scenario. To resolve it, Right Click on the virtual directory - select properties and then click on "Create" next to the "Application" Label and the textbox. It will automatically create the "application" using the virtual directory's name. Now the application can be accessed.
When you have sub-directories in your application, you can have a web.config file for the sub-directory. However, there are certain properties that cannot be set in the web.config of the sub-directory such as authentication, session state (you may see that the error message shows the line number where the authentication or session-state is declared in the web.config of the sub-directory). The reason is, these settings cannot be overridden at the sub-directory level unless the sub-directory is also configured as an application (as mentioned in the above point). Mostly we have the practice of adding web.config in the sub-directory if we want to protect access to the sub-directory files (say, the directory is admin and we wish to protect the admin pages from unauthorized users). But actually, this can be achieved in the web.config at the application's root level itself, by specifying the location path tags and authorization.
in your case the site map section causing the issue. try to remove it from the config file.

This website used to work previously but recently the published version stopped working due to this error. As far as I can tell, the only change was installing iTextSharp and iTextSharp xmlworker through nuget.
I have tried, without success:
giving modify permission on the site folder to Everyone
checking the web.config file, and using an older version of the web.config file (from when the site worked).
uninstalling iTextSharp and iTextSharp XMLWorker
The project still runs without issue from Visual Studio.
This is solved. The error was caused by the folder name not matching the path for the virtual directory. Oh wow I feel dumb.
Check the applicationhost.config file under - .vs\lpsWeb-UI\config folder of your application root.
Under sites section of the config file check what the physical path points to.
If you modify those you should be able to fix the issue.
This is because of different physical path in the IIS.To change the physical path of application content
You can perform this procedure by using the user interface (UI), by running Appcmd.exe commands in a command-line window, by editing configuration files directly, or by writing WMI scripts.
User Interface
To use the UI
Open IIS Manager. For information about opening IIS Manager, see Open IIS Manager (IIS 7).
In the Connections pane, expand the Sites node and click to select the site in which your application runs.
In the Actions pane, click View Applications.
On the Applications feature page, select an application from the list and then click Basic Settings in the Actions pane.
In the Physical path box, change the path of the application content.
Click OK.
DefaultAppPool application pool runs under the Network Service account. This account is local to the computer and this account does not exist on another computer. Make sure that you configure the DefaultAppPool application pool to use an account that is a domain user. Then, you can use the same account on the WorkmenComp file server. Alternatively, you can create a workgroup account on the WorkmenComp file server.
I am getting this HTTP Error 500.19 error when I am giving physical path as Z:\App_Live in IIS
Instead of using z:\ ,
I used network path \\server\share\live_folder in the IIS physical path – something like this \\server\share\wwwroot\inetpub\wwwroot
Also you may need to specify username/password in "connect as".

How to use host headers in IIS for a web application?

I have configured a website in IIS with a host header, so that I can call the url customhostheader/ and the website will be shown.
When I try to publish my web project, I get the error that some sections in web.config are registered as allowDefinition=MachineToApplication. But I cannot convert the website in to an application in IIS. I can only convert virtual directories into IIS applications, but I don't want the much longer url http://customhostheader/virtualdirectoryname, I prefer to have just http://customhostheader.
Any ideas what I could do?
Thanks.
Add an application with the name customhostheader which is pointing to your published code (parent of bin folder)
To do this
Right click on "Default Web Site" in IIS and select "Add
Application"
Give alias as customhostheader and provide the path to your application.
Edit based on the comment
Each website by default contains an application. So we just needs to make sure the path of the website is correct.
The following two points should be enough to set up the correct path
The path should be parent of bin folder
The web.config should be present on the path
The default document can be set through the IIS or web.config

error for work iis and visual studio

i install visual studio 2010,but i forgot to install iis before it,so now when i want to run asp.net programs,it gives me this error:

i do this,but it doesn t work

Do I need a web config file to run an asp.net hello world on IIS 7?

I have uploaded a simple hello world on my IIS server 7 (shared hosting). It doesn't work. Is it necessary to add a web config and what's the minimum in that case ?
Thanks.
Error says:
Server Application Unavailable
The web application you are attempting
to access on this web server is
currently unavailable. Please hit the
"Refresh" button in your web browser
to retry your request.
Here's the script, very basic :)
<%# Page Language="VB" %>
<html>
<head>
<title>ASP.NET Hello World</title>
</head>
<body bgcolor="#FFFFFF">
<p><%= "Hello World!" %></p>
</body>
</html>
A individual, site-specific web.config is not required to be present in order to get a basic "Hello World" site up and running in IIS7, however, it's rather unusual not to have one.
IIS7, unlike previous versions, effectively has the ASP.NET worker process component "built-in". This allows web.config files to specify configuration of not only your ASP.NET site itself, but also how the IIS server hosting your site should be configured (i.e. you can specify (for example) the default document type in an ASP.NET web.config file).
If you don't specify an individual web.config for your ASP.NET site, the IIS7 server will use the "default" web.config, which is usually located in your "windows" folder within the system-wide configuration of the .NET framework itself.
This article:
Working With Configuration Files in IIS 7
from the MSDN library states:
Configuration Files
Configuration exists in a physical
directory in either server-level
configuration files or in Web.config
files. Every configuration file maps
to a specific site, application, or
virtual directory.
Server-level configuration is stored
in the following configuration files:
Machine.config. This file is located in
%windir%\Microsoft.NET\Framework\framework_version\CONFIG.
Root Web.config for the .NET Framework. This file is located in
%windir%\Microsoft.NET\Framework\framework_version\CONFIG.
ApplicationHost.config. This file is located in
%windir%\system32\inetsrv\config.
Site, application, and virtual and
physical directory configuration can
be stored in one of the following
locations:
A server-level configuration file. When configuration for a site,
application, directory, or URL is
stored in a server-level configuration
file, you must use a location tag to
specify the site, application,
directory, or URL to which the
configuration applies.
A parent-level Web.config file. When configuration for an application,
directory, or URL is stored in a
parent-level configuration file, you
must use a location tag to specify the
child at which the configuration
applies.
The Web.config file for the site, the application, or the directory.
When you configure settings for an
application, directory, or URL, the
configuration is stored in the same
directory as the site, application, or
directory. You do not need to use
location tags.
Storing configuration settings in a
parent configuration file is helpful
when:
You want to store configuration settings in a configuration file that
is accessible by only certain users or
groups. For example, the
ApplicationHost.config file is
available only to the Administrator
account and to the members of the
Administrators group on a specific
computer, as well as to domain
administrators when a computer is part
of a domain.
You want to configure a feature at the URL-level (also known as
file-level).
Also, see the following article for further information:
The new Configuration System in IIS 7
EDIT:
Regarding the specific error message that you're getting, I've seen this before on an IIS7 server, and the problem turned out to be the Application Pool that the site was set to use wasn't "running". Going into the IIS7 admin gui and starting the Application Pool cured the problem.
I have also seen this error caused wen the relevant permissions have not been set on the folder containing your website code.
See here, here, and here for further information.
Of course, since you're testing a shared hosting environment, you probably don't have access to the web server itself, and it's difficult to know exactly what you do have access to, administration-wise, through your hosting provider, but they probably have some kind of interface to set permissions on folders/files, so I'd look there first.
Failing that, you may have to include a web.config file in your "test" site as that will allow you to set configurations within IIS7 that you may otherwise have no access to.
Failing that, you may need to speak to your web host's support team.
It should be enough to inherit from machine.config. What's the exception?
I am not sure about the shared Hosting environment. But If you try to create a web application ( try ASP.Net Empty web application template) and just use Response.write("Hello World !") . it will work without any web.config.
I tried my self and it work successfully.
Only problem is that It may ask you if you wanted to debug your application then it requires to add "compilation = true" attribute in web.config.
