can some help me to solve the 0x80070021 error - iis

I am new to iis, when I try to access the site, I get the following error:
Module
IIS Web Core
Notification
BeginRequest
Handler
Not yet determined
Error Code
0x80070021
I tried to search for similar problems through Google, and tried the steps in the link below, but without success.
HTTP Error 500.19 and error code : 0x80070021
Can some one help me? Thanks in advance.

According to your description and error mesage, it seems something wrong with your web.config.
The 0x80070021 error occurs if the specified portion of the IIS configuration file is locked at a higher configuration level.
I suggest you could refer to below article to know how to unlock the configuration.

ISAPI Issues with CFWheels

I am working with a brand new instance of IIS on Windows Server 2012 and I am having trouble getting my CFWheels app to work. The issue it seems to be with ISAPI filters and isapi_redirect.dll because it's trying to find the file in the wrong folder. I tried adding a filter myself which I named jakarta and pointed it to the correct folder of the dll but now I am not getting anything but a blank screen and no error of any sort (before I was getting an error 500)
Anyone with a recommendation of what I need to do!?
I recreated the site under C:\inetpub\wwwroot\ instead of having it on my second HDD and the issue went away.... I would love to know why though so if anyone ever comes across this question please feel free to post

No error code during Deploy using Web Deploy 3.5

I'm totally new to web deployement. I did set up a deploy on one of my project, I did the same thing on another one. But when I try to publish my website, I have this error with no code.
I don't even know where to search for the log file on the IIS server. Can you tell me, Everything is running with default configuration. I just need to know where to find the information so I can publish my website.
I finally found this blog where the solution is explained : http://bartwullems.blogspot.fr/2013/01/webdeploy-error-systemunauthorizedacces.html
I didn't know where to look for the logs but once I found the right log, the error is : System.UnauthorizedAccessException: Attempted to perform an unauthorized operation. at System.Security.AccessControl.Win32.SetSecurityInfo

IIS not able to locate the web.config

I have a deployed a web application in IIS. Which used to work without any issues. Recently i have shifted that web application to another machine, Here is the problem. Once i setup the Webapplication when i opened the default document in IIS im getting the File not found error as following
Internal Server Error
\?\C:\inetpub\wwwroot\application\web.config
I have no clue why the IIS is not able to find the web.config. The file is present in the path C:\inetpub\wwwroot\application\web.config but the IIS is looking in the path \?\C:....
Please let me know how to resolve this??
Firstly this is documented on support.microsoft.com so I would suggest that anyone who has this issue read this first as it covers a number of solutions which I won't
Now from personal experience I encountered this error after setting up a new development machine. What I had forgotten to do was install the Url Rewrite 2.0 IIS module. Sadly the IIS error gives absolutely no idea that this is the actually issue.
Therefore to solve this issue investigate the system.webServer setting in our web.config and ensure that you have installed all the iis modules that you use. I did this by systematically removing elements from my web.config until I came across the cause.
In my case, I was running ASP .NET Core website so I had to install .Net Core Runtime from
https://dotnet.microsoft.com/download/dotnet-core/current/runtime
I know it's old post but I resolved the same issue as follows:
If you are using TFS and you are getting this problem then Reason is ".vs" file is not excluded from commit.
Because of that ".vs\config\applicationhost.config" gets the local version of another user/Developer.
To Solve the error, First open that file Update Physical path inside "" xml tag.
Also ask user to exclude this folder from TFS to prevent future issues.
If you are getting mysql localhost error. What I will do will work for you.

Classic ASP application on IIS7 throwing 500 error [duplicate]

This question already has answers here:

Classic ASP on IIS7: refusing to send errors to browser on 500 Internal Server Error
I have done the following (as suggested in other posts) and still get the 500 error:
Set Send Errors To Brower = true in ASP properties in IIS
Unchecked show friendly errors in browser
Set Error Pages properties to show Detailed Error in IIS
ASP handler does seem to be mapped correctly.
The application pool has been set to Classic mode.
Any other ideas?
Finally sorted this out with the help of my sys admin!
The classic asp application was in a sub-folder. To get it working, the classic asp application's app pool had to be given access to the main folder and not just the sub-folder as it was using assets from the main folder.
Thanks heaps to all those who tried to help. Much appreciated.
From the IIS blog...
Script errors no longer shown in browser by default
As a result of our security paranoia, we turned off ASP's default behavior of sending script errors (including line number and code snippet to the browser.
...
To revert back to IIS6- behavior, simply run the following command:
%windir%\system32\inetsrv\appcmd set config -section:asp -scriptErrorSentToBrowser:true
Hopefully that will at least get you to the line that's throwing the error...
I suspect your running your AppPool under "Integrated" pipeline mode, change this to "Classic" and you should be right.

Try changing the version of .NET that the application pool is running under.
You've not mentioned which version of Umbraco you are using but I'm guessing 4.7.
If so you'll probably need to be running it under .NET4, unless you have specifically downloaded the .NET3.5 version direct from Codeplex.
try to change the port to other number rather than using default 80 port.
hope this helps
