IIS 10 Error 500.19 (0x80070021) - Lock Violation - iis

I have an application I am trying to migrate from Server 2012 IIS 8 to Server 2016 IIS 10. When I initially move everything over I am receiving the attached error message.
I have read through several stack exchange posts and it basically says the section needs to be unlocked. I have unlocked the section via the command prompt command and via the IIS manager.
The section shows unlocked

This issue happens only with Modules which are listed as Native.
To resolve this error you need to unlock this module from the server level.
Open PowerShell as administrator and run this command.
Remove-WebConfigurationLock -pspath 'MACHINE/WEBROOT/APPHOST' -filter "system.webServer/modules/add[#name='WindowsAuthenticationModule']"
After unlocking this restart the iis server and try to access the site again.
You can directly unlock this setting using iis manager GUI option.
Select server name from the iis server node and then select module from feature view.
in modules feature, select which module you want to unlock and then right-click on it and select unlock.
and then restart iis server.

503 error, caused by `iis_ssi.dll failed to load` in the Event Viewer (eventlog)

I'm getting this error in the event log (EventViewer):
The Module DLL C:\Windows\System32\inetsrv\iis_ssi.dll failed to load. The data is the error.
OS is Windows2012 Server. How to fix it?
You need to add SSI in Server Manger. Follow these steps:
Add Roles and Features
In Server Roles, expand Web Server (IIS)
Expand Application Development
Select Server Side Includes
For Windows 2012r2 Operating systems, to be more precise following this step:
Open Server Manager Dashboard
Click on Add Roles and Features
Expand Web Server IIS (if not already selected)
Expand Web Server
Expand Application Development and ensure that all unchecked boxes are selected.
Click Next on the select feature windows to advance
In the Confirm installation selection select specify an alternate source path for the installation CD such as F:\sources\sxs to complete the installation.

msdeploy.axd returns 404

I'm trying to setup webdeploy on IIS8, but why am I getting 404 when accessing both https://[servername]:8172/msdeploy.axd and https://localhost:8172/msdeploy.axd locally.
I've installed management service.
I've installed webdeploy 3.5 using web platform installer. In Program and Features a changed the instalation of webdeploy to include all features including the handler.
In IIS Manager I've chosen Configure Web Deploy Publishing for default website's context menu.
I've restarted management service.
when i tried https://[servername]:8172/msdeploy.axd I was asked to enter credentials and accept the certificate. after that I got 404.
I've uninstalled webdeploy and installed using MSI manually including all features.
restarted entire server.
getting 404.
I don't believe you can open the service from a browser. I attempted that against a dev server that we deploy to many times a day and also received a 404. I would try deploying from VS instead as a test.
Also if anyone comes here and is using Visual Studio Publish dialog and the "Validate Connection" button fails: do NOT use the button when creating. Just click Ok, then Edit (in More actions menu).
In the Connection tab, click Validate Connection. This time it will asks you to accept an invalid certificate (since you likely self-signed it on your server). Accept it and the connection should go through.

After adding SSL to local IIS "Unable to start debugging on the Web server"

Visual Studio 2015 (Loaded as Admin), Web API 2, Windows 10.
I have Local IIS with a subdomain sub.mylocalsite.com mapped through the hosts file to 127.0.0.1. The Web API 2 is loading and I am able to debug and do all the activities as expected.
On IIS, if I add a secure binding, with the proper self-signed certificate (without disabling the non-secure binding, i.e. keeping two bindings) and do an IIS Reset, I am able to access the https Web APIs as expected, however, when I click run to start debugging I get the standard error from VS of Unable to Start Debugging.
Please note that I tried both setting the start URL as http://sub.mylocalsite.com and https://sub.mylocalsite.com to no avail
Any solution?
I experienced the same thing, then saw this blog post. Try attaching to worker process, per this blog post:
https://blogs.msdn.microsoft.com/vijaysk/2007/10/17/visual-studio-debugging-websites-that-require-client-certificates/
The most important requirement for the pretty F5 key to work in Visual Studio is NTLM/Windows Intergated Authentication. Only then can it auto-attach to the IIS worker process. And this is where our trouble starts. Client certificates is a kind of an authentication mechanism. When you configure a website to require client certificates you are changing the authentication mechanism.
So if you are developing a website off an IIS server and you need to debug it with client certificates then you cannot just open your web project in visual studio and start debugging it. But what you can do is attach to the process running your code manually.
Open your project in Visual Studio and set a breakpoint as you usually do
Debug menu > Attach to Process > Select the process running your code.

ASP Error 0223 - TypeLib Not Found, intermittent, resolved after IIS restart

I'm currently in the process of migrating an ASP platform from Windows 2003 R2 IIS 6 web servers to Windows 2012 R2 IIS 8.5 web servers. I'm at the stage where I've migrated a number of sites across to two separate 2012 web servers, all looked great, clients and developers are happy... However the following error has presented itself after a few days hosting on one of the new servers.
Active Server Pages error 'ASP 0223'
TypeLib Not Found
/jobboard/conf/constants.vbs.inc, line 1
METADATA tag contains a Type Library specification that does not match any Registry entry.
The METADATA tag is below:
<!--METADATA TYPE="typelib" NAME="Microsoft ActiveX Data Objects 2.8 Library" UUID="{2A75196C-D9EB-4129-B803-931327F72D5C}" VERSION="2.8"-->
Restarting IIS on this server resolved the issue (albeit temporarily).
Subsequently the other 2012 web server in production presented the same error a couple of days later, again, restarted IIS and works for now.
I've checked the registry and the relevant tag exists with the right UUID and correct permissions.
It doesn't affect all sites on the server, only all sites in a particular application pool.
The application pools use a domain user identity and sites are split up into a number of shared pools.
I've now determined what was causing the above problem...
Our sites on IIS run in a number of shared application pools running as a domain user. We also have a Windows scheduler job which runs a number of scripts over night which also run as the same domain user.
It seems there are cases when this scheduler job runs it interferes with the IIS worker processes. When it completes and ends its user session it unloads the registry file in memory, which the w3wp.exe processes could also using.
This error is presented in the Event log...
Windows detected your registry file is still in use by other
applications or services. The file will be unloaded now. The
applications or services that hold your registry file may not function
properly afterwards. No user action is required.
Along with references to the w3wp.exe processes currently running.
It was replicated when I terminal serviced in as the domain user and logged out again after a period of time. The event log presented the error and the sites all bombed shortly afterwards.
Running the scheduled job as a different user has fixed this issue for us.
I remember having an include file for ADOVBS.inc with all the ADO constants inside and including it as a standard ASP include inside my global include file which is included on every page on the site.
This was before I used the META way of including the file.
So maybe a last resort is to revert to that method of loading in the ADO constants.
It seems like some sort of threshold is being hit, CPU/Memory?, which then prevents IIS caching/loading the file in from the registry. This then causes the error and a recycle of the pool. As no redirect is being done to the 500.100.asp error handler page which hides the error details from the user. It would suggest the error is in IIS and related to the server.
Thanks

Unable to start debugging on the web server. The underlying connection was closed. The connection was closed unexpectedly

All of the sudden I'm getting the following error on my local web server (Win7 64bit, IIS 7.5). I've uninstalled & reinstalled IIS locally and it didn't fix it. IIS is set to start up automatically and I can see that the service has been successfully started. Upon a fresh reboot if I go into IIS and click on start website I get the following error:
The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020
If I try to start debugging on my local website project I get the following error:
Unable to start debugging on the web server. The underlying connection was closed. The connection was closed unexpectedly.
Any ideas on what I can try? I've been doing research on the issue and Microsoft suggest making sure no other service is listening on the same ports. I've verified that this isn't the issue.
Try changing the web site to use a port other than 80 (suggest 8080 for example) and see it if will start. If so that's a sure sign of another service using port 80 (Skype is a common culprit for this).
Application pool's identity password changed?
I know this is an old post, but I can't believe how many times I've been bitten by this. Some shops use integrated security for SQL, and often then on your local IIS needs your network login for the application pool. When your password expires, and you forget to change your password here, start banging your head on the wall... DOH!
Open IIS. Select Application Pools. Select the application pool used by your app. Click Advanced Settings... Select Identity, and the little "..." button to update your user/password.
