I've encountered an error deploying a site to a server. When trying to load the home page, or access authentication on the new site in IIS, I get the error:
Config Error: This configuration section cannot be used at this path.
This happens when the section is locked at a parent level. Locking is
either by default (overrideModeDefault="Deny"), or set explicitly by a
location tag with overrideMode="Deny" or the legacy
allowOverride="false".
More detail can be found here, in Scenario 7 matches my hex error code.
The solution given on the linked site above is to set Allow for overrideModeDefault in the section mentioned in my error, in the applicationHost.config file. In my case, under Security in system.webServer. But if I look at the applicationHost.config on my local computer, where the site is properly deployed already, that section is set to Deny.
If this solution is correct, how is my local instance running just fine with the same web.config? According to my applicationHost.config, that section should be locked, but it's not. I'd prefer to not change the applicationHost.config file, because there are many other sites running on that server. Is there another solution?
I had the same problem. Don't remember where I found it on the web, but here is what I did:
Click "Start button"
in the search box, enter "Turn windows features on or off"
in the features window, Click: "Internet Information Services"
Click: "World Wide Web Services"
Click: "Application Development Features"
Check (enable) the features. I checked all but CGI.
btw, I'm using Windows 7. Many comments over the years have certified this works all the way up to Windows 10 and Server 2019, as well.
You could also use the IIS Manager to edit those settings.
Care of this Learn IIS article:
Using the Feature Delegation from the root of IIS:
You can then control each of machine-level read/write permissions, which will otherwise give you the overrideMode="Deny" errors.
For Windows Server 2012 and IIS 8, the procedure is similar.
The Web Server (IIS) and Application Server should be installed, and you should also have the optional Web Server (IIS) Support under Application Server.
Browse to “C:\Windows\System32\inetsrv\config” (you will need administrator rights here)
Open applicationHost.config
Note: In IISExpress and Visual Studio 2015 the applicationHost.config is stored in $(solutionDir).vs\config\applicationhost.config
Find the section that showed up in the “config source” part of the error message page. For me this has typically been “modules” or “handlers”
Change the overrideModeDefault attribute to be Allow
So the whole line now looks like:
<section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Allow" />
After saving the file, the page loaded up fine in my browser.
Warning:
Editing applicationHost.config on 64-bit Windows
You need to unlock handlers. This can be done using following cmd command:
%windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/handlers
Maybe another info for people that are getting this error on IIS 8, in my case was on Microsoft Server 2012 platform. I had spend couple of hours battling with other errors that bubbled up after executing appcmd. In the end I was able to fix it by removing Web Server Role and installing it again.
1. Open "Turn windows features on or off" by: WinKey+ R => "optionalfeatures" => OK
Enable those features under "Application Development Features"
Tested on Win 10 - But probably will work on other windows versions as well.
I ran these two commands from an elevated command prompt:
%windir%/system32/inetsrv/appcmd unlock config /section:anonymousAuthentication
%windir%/system32/inetsrv/appcmd unlock config /section:windowsAuthentication
As per my answer to this similar issue;
Try unlocking the relevant IIS configuration settings at server level, as follows:
Open IIS Manager
Select the server in the Connections pane
Open Configuration Editor in the main pane
In the Sections drop down, select the section to unlock, e.g. system.webServer > defaultPath
Click Unlock Attribute in the right pane
Repeat for any other settings which you need to unlock
Restart IIS (optional) - Select the server in the Conncetions pane, click Restart in the Actions pane
This Did the trick for me, for IIS 8 Windows server 2012 R2
Go to "Turn on Features"
Then go to all default setting , Next, Next, Next etc..
Then, select as shown below,
Then reset IIS (optional) but do it safer side.
This is an additional solution as its a generic problem everyone have different of problem and thus different solution. Cheers!
The best option is to Change Application Settings from the Custom Site Delegation
Open IIS and from the root select Feature Delegation and then select Application Settings and from the right sidebar select Read/Write
On Windows Server 2012 with IIS 8 I have solved this by enabling ASP.NET 4.5 feature:
and then following ken's answer.
To fix this open up the IIS Express applicationhost.config. This file is stored at C:\Users[your user name]\Documents\IISExpress\config\applicationhost.config
Update for VS2015+: config file location is $(solutionDir).vs\config\applicationhost.config
Look for the following lines
<section name="windowsAuthentication" overrideModeDefault="Deny" />
<section name="anonymousAuthentication" overrideModeDefault="Deny" />
<add name="WindowsAuthenticationModule" lockItem="true" />
<add name="AnonymousAuthenticationModule" lockItem="true" />
Change those lines to
<section name="windowsAuthentication" overrideModeDefault="Allow" />
<section name="anonymousAuthentication" overrideModeDefault="Allow" />
<add name="WindowsAuthenticationModule" lockItem="false" />
<add name="AnonymousAuthenticationModule" lockItem="false" />
Save it and refresh Asp.net Page.
In our case on IIS 8 we found the error was produced when attempting to view Authentication" for a site, when:
The server Feature Delegation marked as "Authentication - Windows" = "Read Only"
The site had a web.config that explicitly referenced windows authentication; e.g.,
Marking the site Feature Delegation "Authentication - Windows" = "Read/Write", the error went away. It appears that, with the feature marked "Read Only", the web.config is not allowed to reference it at all even to disable it, as this apparently constitutes a write.
Seems that with IIS Express and VS 2015, there's a copy of the applicationHost.config file at $(solutionDir).vs\config\applicationhost.config so you'll need to make changes there. See this link: http://digitaldrummerj.me/iis-express-windows-authentication/
Make sure these lines are changed per below:
<section name="windowsAuthentication" overrideModeDefault="Allow" />
<section name="anonymousAuthentication" overrideModeDefault="Allow" />
<add name="WindowsAuthenticationModule" lockItem="false" />
<add name="AnonymousAuthenticationModule" lockItem="false" />
In my case it was that on server was not enabled "HTTP Activation" under .NET Framework Features. So for Windows Server 2012 the solution which worked for me was:
Server Manager -> Add roles and features -> Features -> make sure that under .NET Framework of version you want to use is checked "HTTP Activation"
The Powershell way of enabling the features (Windows Server 2012 +) - trim as needed:
Install-WindowsFeature NET-Framework-Core
Install-WindowsFeature Web-Server -IncludeAllSubFeature
Install-WindowsFeature NET-Framework-Features -IncludeAllSubFeature
Install-WindowsFeature NET-Framework-45-ASPNET -IncludeAllSubFeature
Install-WindowsFeature Application-Server -IncludeAllSubFeature
Install-WindowsFeature MSMQ -IncludeAllSubFeature
Install-WindowsFeature WAS -IncludeAllSubFeature
The error says that the configuration section is locked at the parent level.
So it will not be directly 1 config file which will resolve the issue,
we need to go through the hierarchy of the config files to see the inheritance
Check the below link to go through the File hierarchy and inheritance in IIS
https://msdn.microsoft.com/en-us/library/ms178685.aspx
So you need to check for the app config settings in the below order
ApplicationHost.config in C:windows\system32\inetsrv\config. Change the overrideModeDefault attribute to be Allow.
ApplicationName.config or web.config in the applications directory
Web.config in the root directory.
Web.config in the specific website (My issue was found at this place).
Web.config of the root web (server's configuration)
machine.config of the machine (Root's web.config and machine.config can be found at - systemroot\MicrosoftNET\Framework\versionNumber\CONFIG\Machine.config)
Go carefully through all these configs in the order of 1 to 6 and you should find it.
I noticed one answer that was similar, but in my case I used the IIS Configured Editor to find the section I wanted to "unlock".
Then I copied the path and used it in my automation to unlock it prior to changing the sections I wanted to edit.
. "$($env:windir)\system32\inetsrv\appcmd" unlock config -section:system.webServer/security/authentication/windowsAuthentication
. "$($env:windir)\system32\inetsrv\appcmd" unlock config -section:system.webServer/security/authentication/anonymousAuthentication
I needed to change the SSL settings on a subfolder when i got this nice message. In my case following action helped me out.
Opened C:\Windows\System32\inetsrv\config\applicationHost.config
And changed the value from overrideModeDefault="Deny" to "Allow"
<sectionGroup name="system.webServer">
...
<sectionGroup name="security">
<section name="access" overrideModeDefault="Allow" />
</sectionGroup>
In my case, I got this error because I was operating on the wrong configuration file.
I was doing this:
Configuration config = serverManager.GetWebConfiguration(websiteName);
ConfigurationSection serverRuntimeSection = config.GetSection("system.webServer/serverRuntime");
serverRuntimeSection["alternateHostName"] = hostname;
instead of the correct code:
Configuration config = serverManager.GetApplicationHostConfiguration();
ConfigurationSection serverRuntimeSection = configApp.GetSection("system.webServer/serverRuntime", websiteName);
serverRuntimeSection["alternateHostName"] = hostname;
in other words, I was trying to operate on the website's web.config instead of the global file C:\Windows\System32\inetsrv\config\applicationHost.config, which has a section (or can have a section) for the website. The setting I was trying to change exists only in the applicationHost.config file.
In my case, it was something else.
When I loaded the solution in a new version of Visual Studio, VS apparently created a new project-specific applicationhost.config file:
MySolutionDir\.vs\config\applicationhost.config
It started using the settings from the new config, instead of my already customized global IIS Express settings.
(\Users\%USER%\Documents\IISExpress\config\applicationhost.config)
In my case this was the setting that needed to be set. Of course it could be something else for you:
<section name="ipSecurity" overrideModeDefault="Allow" />
Received this same issue after installing IIS 7 on Vista Home Premium. To correct error I changed the following values located in the applicationHost.config file located in Windows\system32\inetsrv.
Change all of the following values located in section -->
<div mce_keep="true"><section name="handlers" overrideModeDefault="Deny" /> change this value from "Deny" to "Allow"</div>
<div mce_keep="true"><section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Deny" /> change this value from "Deny" to "Allow"</div>
Can You try this:
Go to application path where you're getting deny error, right click
Properties->Security tab
In that, change the permissions and check the checkbox read and write. Then it will work without any error hopefully.
For Windows Server 2008 and IIS 7, the procedure is similar.
please refer to this:
http://msdn.microsoft.com/en-us/library/vstudio/bb763178(v=vs.100).aspx
in add role service, u will see "Application Development Features"
Check (enable) the features. I checked all.
In my case I was getting this error when attempting to update the authentication settings in IIS also in addition to browsing. I was able to remove this error by removing the authentication setting from the web.config itself. Removing a problematic configuration section may be less invasive and preferable in some cases than changing the server roles and features too much:
Section Removed:
<security>
<authentication>
<windowsAuthentication enabled="true" />
</authentication>
</security>
I had the similar issue, but I used the following powershell script which helped me to achieve above steps in on button click.
#Install IIS
Import-Module ServerManager
Add-WindowsFeature Web-Server, Web-Asp-Net45, Web-Mgmt-Console, Web-Scripting-Tools, NET-WCF-HTTP-Activation45, Web-Windows-Auth
the list of features can be added or removed based on the requirement.
I had an issue where I was putting in the override = "Allow" values (mentioned here already)......but on a x64 bit system.......my 32 notepad++ was phantom saving them. Switching to Notepad (which is a 64bit application on a x64 bit O/S) allowed me to save the settings.
See :
http://dpotter.net/technical/2009/11/editing-applicationhostconfig-on-64-bit-windows/
The relevant text:
One of the problems I’m running down required that I view and possibly edit applicationHost.config. This file is located at %SystemRoot%\System32\inetsrv\config. Seems simple enough. I was able to find it from the command line easily, but when I went to load it in my favorite editor (Notepad++) I got a file not found error. Turns out that the System32 folder is redirected for 32-bit applications to SysWOW64. There appears to be no way to view the System32 folder using a 32-bit app. Go figure.
Fortunately, 64-bit versions of Windows ship with a 64-bit version of Notepad. As much as I dislike it, at least it works.
I had the same issue.
Resolved it by enabling Application Server feature. Restarted iis
after that.
This worked for me
Also in IIS 8 you can solve this problem by changing the server to IIS Express. Goto debug->Properties
In the Web select the server as IIS Express from the dropdown and then rebuild the solution
To make a change at Application Level (Web.Config):
Please remove the Trust Level from the web.config:
Actually I was getting this error when I was trying to host my Website on the Hosting Server where I don't have control on their Server. Removing the above line from my Application web.config solved my issue.
I have searched every topic and it seems that everyone got there problem solved already and I have tried all the possible solution they have provided or I am still missing something.
FireWall already turned off.
Ok so I am trying to access my IIS server Application that is currently run by VS 2013. Update 2.
when I try to access http://localhost:29790/ <- this to http://192.168.1.3:29790 which is my current IP on my local. It gives me 503 error.
I have searched for the solution and gives my a tons of.
applicationhost.config file
<site name="SMApplication(4)" id="10">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\Users\DanZe3\Documents\Visual Studio 2013\Projects\SMApplication\SMApplication" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:29790:localhost" />
</bindings>
</site>
I have tried this.
*:29790:*
*:29790:
:29790:
by chaining the bindings. But it is still not working. I restart the PC or the VS as well. But the problem is, when I try to re-open VS. VS overwrite the applicationHost.config and add another binding.
As you can see in my site named "SMApplication(4)" (It has made 4 already!) This is automatic when I re-open the file
and then the bindings will be *:29790:localhost again.
Somehow Editing this bindings. Visual Studio will create another binding of the application, having another site named SMApplication(5).
I have tried to remove the localhost on the *:29790:localhost, but when I run the application it gives me.
Unable to Launch IIS Express Web Server.
The start URL specified is not a valid. http://localhost:29270/
I had a similar problem with a similar solution:
Scenario: I had the app pool running under an user account and it's password had been changed because it had expired. I never updated IIS so the app pool would stop by itself every time when a try to run website. Even if I start AppPool manually, It stopped on website run.
Solution: update the credentials for the account on IIS or use another account
I
Application's DefaultAppPool (or other custom name) may have stopped for some reason. Make sure it is on. Recycle too.
I have faced this issue recently after Windows 10 update (Dev machine).
I have created a new IIS AppPool and assigned to the website and that fixed the issue.
You should try to remove IIS Express folder at %USERPROFILE%\Documents.
Next important thing is to restart Visual Studio and open it as admin.
Then you can right click your ASP.NET project and go into Properties view. There you can configure web settings for IIS hosting in the Web tab. Try to change IIS settings here and then save with Ctrl+S.
When there is a * next to the web tab because you tried to edit settings but could not save, you need to change to another tab, switch back to Web tab and then save with Ctrl+S. (The Properties view for ASP.NET apps in Visual Studio is still buggy ...)
I am currently using Visual Studio 2015 CE so I don't know whether my solution applies to your problem. Anyways try to remove any folders that got cached by IIS Express hosting and never really got cleaned up afterwards.
So, in my case the only thing that fixed this was setting the ip statically in a new binding protocol, in your case would be something like this:
<site name="SMApplication(4)" id="10">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\Users\DanZe3\Documents\Visual Studio 2013\Projects\SMApplication\SMApplication" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:29790:localhost" />
<binding protocol="http" bindingInformation="*:29790:192.168.1.8" />
</bindings>
</site>
This won't cause any problem in a production environment.
I want to test some subdomain features in an asp.net site. I read just to edit the hosts file and add 127.0.0.1 subdomain.domain.com and that should work.
But mine seems to not. I have flushed the dns, restarted, tried new browsers and still get error 500.
When I normal run the asp.net site from Visual Studio it goes to http://localhost:17365/ . How do I get the IP address for this?
I guess I don't get the whole picture and missing some pieces.
I ran netstat -n and see that the site is running on[::1]:17365 maybe thats why its not working under ipv4?
The solution is very simple.
After you have edit your host files adding a line as:
127.0.0.1 subdomain.domain.com
you run your site, the personal web starts and you get on your browser this
http://localhost:[PortNumber]/ (eg: http://localhost:17365/ )
just change it to
http://subdomain.domain.com:[PortNumber]/ (eg:http://subdomain.domain.com:17365/)
with your hand, type it on the url on your browser, and it will work.
In visual studio when you go to run the site first change in the Website Properties > Use Dynamic PortstoFalse, then set the Port Numberto80, then run it.
It will by default launch http://localhost:80, however then in your browser visit subdomain.domain.com in your browser it will point to your debugging instance of your site (assuming you've still got that 127.0.0.1 subdomain.domain.com in your hosts file).
I just go to Project Properties > Web and under Servers, I select Use Local IIS Web server and set the Project Url to subdomain.domain.com.
Someone has registered "lvh.me" that point to 127.0.0.1
So you can use:
http://lvh.me
http://something.lvh.me
You have to configure your web server also.
Ok, you changed the hosts file. Your system (dns) knows where to go (127.0.0.1) with the host.
But your web server still know nothing about subdomain.domain.com and associates nothing with it.
When you normally start an asp.net site in Visual Studio it uses the Cassini webserver.
I'm not sure if you can configure bindings for Cassini.
My suggestion would be to configure a website or virtual directory in IIS with bindings to subdomain.domain.com, look here on how to do that: Add a binding to a site
Your hosts file should contain this:
127.0.0.1 subdomain.domain.com
The request of subdomain.domain.com will then be redirected to your Local IIS Web server (on port 80), because of the binding configuration IIS knows where to look for your website.
Within the properties of your web project in Visual Studio you can configure to use Local IIS Web server in the Web tab.
I'm not sure that the Visual Studio Development Server can handle bindings to anything other than localhost. I think the only thing you can change is the port number.
You have a couple of options.
1) Install IIS Express (or full-on IIS if you want) and configure Visual Studio to point to the site you have set up in there. You can manually set up your binding to subdomain.domain.com and it's very flexible. Take a look at this answer: Using Custom Domains With IIS Express
2) Install a port forwarder like rinetd (I think this should work if you have the entry in your hosts file). You should be able to map subdomain.domain.com:<some port number> to localhost:17365. Note that rinetd won't detect the domain you're using (just the underlying IP address which is 127.0.0.1), so it's best to use a distinct port for each project you're working on.
Goto applicationhost.config, you can find on windows tray.
Finding application.config of a current running project in IIS
Now find
<webLimits>
......
<sites>
.....
<site name="[YourProjectName]" id="[YourProjectID]">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="[Your Project Path]" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:50569:[Remove localhost from here]" />
</bindings>
</site>
.....
</sites>
......
<webLimits />
Remove localhost from bindingInformation.
Finally, Run VisualStudio as Administrator
I'm using VS 2017 and Webforms (don't say it).
In the Solution (.sln) file (in notepad) I changed the port to 8080. This was found in several properties, including VWDPort, Debug.AspNetCompiler.VirtualPath, Debug.AspNetCompiler.TargetPath, Release.AspNetCompiler.VirtualPath, and Release.AspNetCompiler.TargetPath
In the applicationhost.config file, I added:
<binding protocol="http" bindingInformation="*:8080:subdomain.domain" />
Also done in notepad. Make sure there are no duplicate or old entries anywhere in this file for bindings. After you change the port in Step 1 you may get an auto-generated duplicate entry with old bindings. Also, be sure you editing the correct applicationhost.config file. This file is in a different place depending on your version of VS.
In Powershell, run: "netsh http add urlacl url=http://subdomain.domain:80/ user=everyone"
In your hosts file (mine is in C:\Windows\System32\drivers\etc) add "127.0.0.1 subdomain.domain" to your hosts listing. You'll have to be an administrator (right-click on notepad, run as administrator)
Run VS as Administrator. This will keep the port to 80. If not run as administrator, you'll get a random port number, your .sln file will get auto-edited with this number, and you'll get duplicate bindings in applicationhost.config.
Running as Administrator is irritating, but it's the only way I could get the port to not change. Also, I tried using other ports, such as the one randomly assigned VS, but kept running into 503 errors from IIS.
Using this you could get a list of IP addresses if I add this code it resolves to
127.0.0.1 please confirm if this is what you are looking for otherwise I will remove the answer
foreach (IPAddress address in Dns.GetHostAddresses("localhost"))
{
Console.WriteLine(address.ToString());
}
