IIS 8.5 not using applicationHost.config? - asp.net

Using Windows server 2012 R2 with IIS 8.5.9600.16384
I wanted to change some config options for the IIS because i have a slow first load issue.
All documents i can find tell me that i should edit " C:\Windows\System32\inetsrv\config\applicationHost.config ". But i'm fairly certain that this isn't the config file used by the IIS. The file still contains older application pools/websites and is missing newer ones. Also when i make a change in the IIS interface this doens't change the config file.
Any thoughts on what might be happening here ?

Exact same problem here, but finally found the answer: Applicationhost.config not showing changes! Unbelievable but true answer: Notepad++ does not open the actual version of applicationHost.config. Restart IIS Manager, download and install Notepad2 x64 and everything should work as expected.

Local Host redirected you too many times Issue with IIS

I am working on bringing a working web application onto a new computer running Visual Studio 2022 version 17.4.2 and .NET Framework 4.7.2. When running on local IIS (version 10.0) host there is a "local host redirected you too many times" issue. It suggests clearing cookies which has been done with no effect.
The same code works on other machines with no issues. Is there anything in IIS set up/configuration or that may be missing from Visual Studio or other installations? Thanks in advance.
So far we have tried debugging the code and including breakpoints for where the issue may be occurring, ensuring that the installations of windows feature and IIS management is the same as another where the program is working. Also created a .txt file that can be reached on local host and is in same location as the rest of the project.
Here are a few things you can try:
Try on another machine.
Try to remove as much rules as possible from web.config and keys and so on. Or if it's a single page you're having the error with try to remove as much code from it especially if there are redirect codes. And add breakpoints and debug.
Check the LOCAL application pool version if it's set same as the online .net framework version.

You do not have permission to access the IIS configuration file - Web app error

I am trying to load existing c# web applications and getting below errors while loading any web project:
Creation of the virtual directory http://localhost:/ failed with the
error: You do not have permission to access the IIS configuration
file. Opening and creating web sites on IIS requires running Visual
Studio under an Administrator account.. You will need to manually
create this virtual directory in IIS before you can open this
project.
The following error occurred when trying to configure IIS Express for
project xxx.WebApi. You do not have permission to access the IIS
configuration file. Opening and creating web sites on IIS requires
running Visual Studio under an Administrator account.
I tried following, but in vain:
Running VS 2017 pro as an administrator.
I ensured that I have access to %systemroot%\System32\inetsrv\ and C:\Windows\System32\inetsrv\Config folders.
I have installed all IIS compatibility windows features through control panel.
Restarted IIS manager.
Created virtual directories.
Changed registry path of HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Personal from u:\ to C:\Users\MyUser\Documents.
Uninstalled IIS Express 10.0 from control panel and reinstalled it through VS2017 installer by clicking – Individual components – cloud, database server – IIS Express.
Repaired VS 2017.
Got admin access on machine.
Created new empty web project but getting same error while new console app runs without errors.
Restarted machine after every installation related change.
All the solutions tried are mentioned on stackoverflow but are not working for me. Is there something trivial that I am missing? Please guide me to crack these IIS errors.
I was able to solve this issue doing the following:
1- Go to C:\Windows\System32\inetsrv and double click on directory config and accept the warning message.
2- Go to C:\Windows\System32\inetsrv\config directory and double click on directory Export and accept the warning message.
Then you will be able to run the app in your local IIS without being an administrator. You can follow the path in the given Image.
This solved the problem for me with Visual Studio 2017, .Net Core 2.2 and IIS Express 10.
You need to ensure devenv.exe has sufficient permissions. You can find it at:
C:\Program Files OR Program Files (x86)\Microsoft Visual Studio nn.n\Common7\IDE
Right click on the exe, select Properties, Security. I gave Administrators full control as I'm running VS under admin.
My Simple solution was to right click on Visual Studio and click Run as Administrator. But a solution above tells you how to have Visual Studio always run without having to run as an administrator.
All these solutions could not work for me. The issue was, I have accidently uninstall IIS from control panel even it was install and showing me. but was removed from control panel. I reinstall IIS latest version and able to fixed the problem. This might help for others.

VS2017 RC - The following error occurred when trying to configure IIS Express
The issue for me was caused when I modified my project to override application root URL. After a push/merge and new branch my project would not load any longer. reverted the changes and all is well again.
Open an elevated command prompt and enter the following command to substitute a drive path for U drive.
c:\windows:\system32> Subst u: C:\Users\MyUser\Documents
I had replaced ‘U:’ path in registry with ‘C:\Users\MyUser\Documents’ previously. I think that was not sufficient. Some references of u:\ might have been hindering IIS.
The total substitute command must have replaced all references and the IIS config error got resolved. Hopefully, now I’ll be able to load my web apps.
I had the same issue, but instead of the workarounds (such as first double-clicking certain directories each time or running the security risk of always having to always run my VS as administrator), was able to permanently resolve the issue by deleting the "ProjectName.csproj.user" file and that fixed it. I guess there was some incompatible setting in the user file that VS couldn't deal with.
For older versions, change the option from IIS to your solution name, before clicking on the green play like run button, to build and run the application.
We resolved this by removing the project and adding it back.
If you're used to run your Visual Studio via shortcut with 'Run as administrator' checkbox marked, double check it is indeed still selected. For some reason mine had unchecked itself resulting in inability to load an IIS project. I was 100% sure my VS had these administrative privileges as usual, which made me try all the Internet proposed solutions except for the most obvious one.
Restarting Visual Studio worked for me.

Can't run IIS Express from VS2015

I've made everything like it has been described here. But when I started my Visual Studio project - it said: "Unable to launch the IIS Express Web server". The start URL specified is not valid. http://dev.local/". By the way, I can launch it, using cmd ("run as administrator", ofc):
> iisexpress /site:WebApiLocal
So, whats the problem? Where am I wrong?
P.S. Visual Studio has been launchedwith admin's rights.
Ok, I had found solution. I've used local applicationhost.config, which placed in {SolutionDir}.vs\config directory. So, if you have the same problem, check this file or go to the {UsersProfileDirectory}\Documents\IISExpress\config and edit applicationhost.config. Also, you can edit in .csproj tag UseGlobalApplicationHostFile saying to project what kind of applicationhost you want to use:
<UseGlobalApplicationHostFile>True</UseGlobalApplicationHostFile>
Thanks everybody for ideas!
This can happen if you use an external program (e.g. git) and accidentally delete the applicationhost.config file. A restart of visual studio recreated the file in my case, and it started working again.
According to other posts, Visual Studio 2015 specifically requires the site bindings to use localhost as host name. No matter what posts show you that you can otherwise modify the config, the modification just works under command line but not in VS.
Either Microsoft patches VS later in an update, or you revert your manual changes.
I meet the same issue after I enable remote requests in IIS Express. to solve this, you have to remove the urlacl you set before.

Unable to find script library WebUIValidation.js

Hi having some problem with a webserver and some webpages on it, everytime they refresh a popup with this error displays:
Unable to find script library '/aspnet_client/system_web/1_1_4322/WebUIValidation.js'. Try placing the file manually, or reinstall by running 'aspnet_regiis -c'
There are hundreds of answers on google with the following solutions:
1. Run aspnet_regiis -c
2. Replace or copy the file/folders manually
but what to do when the above doens't work.
This webapplication I'm running is using dot.net 1.1 and is located under Default Web Site/App Name/. A aspnet_client directory exist below that virtual directory and contains the WebUIValidation.js file, the aspnet_client directory also lies in the c:\inetpub\wwwroot.
The server is a webserver/sql server, win 2003 IIS 6.
Microsoft dot.net framework 1.1,2.0,3.0,3.5 seems to be installed(Add or Remove programs).
I suspect there is some problem with having all these dot.net version.
Any help is highly appreciated.
I just ran into this problem as well. Plenty of posts listed solutions that didn't work for me. What did work was to check the "Integrated Windows Authentication" on the website node (Right click Web Site -> Properties -> Directory Security) in the IIS 6 manager. It's strange to me that something that had been running fine for years, had this problem all of the sudden.

Error : "Unable to start debugging on the web server..." ASP.NET 4.0

I am getting an error when I want to create a web site on IIS server. I am using Windows 7 and Visual Studio 2010.
Do I have to register or configure asp.net 4.0 for the IIS ?
There aren't many details here, but I was getting that same error while trying to Start Debugging on a web application project in Visual Studio 2010 that I'd just changed from 3.5 to 4.0.
This solved the problem for me from the command line:
cd %windir%\Microsoft.NET\Framework\v4.0.30319
aspnet_regiis.exe -i
Just make sure to go into IIS Manager afterwards and double-check your application pools and such, since it's likely that this will reset some of your configuration.
This did the trick for me:
In IIS > under .NET compilation
Note: Default Website is selected only for screenshot purposes.
Changing the Debug option to True
This error can appear if the password for the account used by the application pool changes. If you start getting this error after changing your network password you may need to update it for the application pool used by your local web sites as well.
In Visual Studio 2010 this usually means there is a problem with Web.Config file that cannot be displayed in Debug mode. So, simply start the app using Ctrl F5 to run in normal mode will tell you which line in Web.Config is faulty.
Check that the path of your site in IIS points to the path of your web project in VS.
I ran across this before and it was an issue of mismatched paths. If you've configured Visual Studio to use IIS and later on changed paths, IIS isn't updated automatically. You need to manually go into IIS and update the path.
Make sure your site is setup to debug (debug="true") under web.config file
<compilation targetFramework="4.0" debug="true">
For me this was related to this solution: http://www.codeproject.com/Questions/83338/Does-not-have-write-access-to
cd %windir%\Microsoft.NET\Framework64\v4.0.30319
aspnet_regiis -i
aspnet_regiis -ga "IIS APPPOOL\DefaultAppPool"
Note this didnt work after I did it on Framework folder and then worked after I did it on Framework64 folder. I guess do both to be sure.
Tried running vs2010 as administrator?
Also try
1. Open IIS. Click “Default Web Sites”.
Check if “Anonymous Authentication” is enabled.
Enable “Windows Authentication” as well.
I've had this several times - in my case it's always that I've not updated my hosts file so VS is trying to locate an external DNS instead of my local one.
I spent a few hours fighting with this issue. In the end it seems to be that some changes made outside VisualStudio had confused it. I don't know what the issue actually was but things started to work again when I opened a different version from the same solution so that VisualStudio (or IIS) did some magic on the IIS configuration. Then I changed back to the original solution, the configuration was again modified - and now debugging works again.
Another reason would be if you have SSL Certificate installed on IIS. You will have to disable the SSL from IIS manager for the application that you are debugging. Because Visual Studio tries to launch it as http instead of https.
In my case, I was receiving a 0x80004005 error message box in VS2019.
That was caused by HSTS being enabled in the "Advanced properties" on the website.
Screenshot of advance site settings in IIS
Found this post which seems useful if someone wants to do debugging with HSTS being enabled: https://scatteredcode.net/debugging-on-localhost-with-hsts/
I get this same error every time I set my project file as a share.
I resolved it by going into the security tab of the file and re-adding "IIS AppPool\DefaultAppPool"
In my case, i have to change the certificates bindings in IIS>Default Web Site > Binding.
IIS Binding
If you are using Visual Studio, you need to check what server you are trying to run your application on.
Right click on the project
-> Web
-> Servers
-> In the first dropdown choose "IIS Express" (To debug with VS).
