After a company forced Windows 10 update today, the Application Pool required by a local web application keeps stopping/crashing displaying the message
Service Unavailable
HTTP Error 503. The service is unavailable.
I have checked the the below similar posts and followed the solutions provided with no luck.
#1 - https://stackoverflow.com/questions/47338226/iis-10-0-apppool-crashing-causing-503-error
For hosting .Net Core applications in IIS, .Net CLR Version of
application pool should be No Managed Code as shown in below
screenshot.

Go to the drive your IIS is installed on, eg. C:\inetpub\temp\appPools\
Delete the directory (or virtual directory) with the same name as your app pool.
Recycle/Start your app pool again.
I have also followed the Microsoft instructions. Made sure to first follow the steps in "Turn Windows features on/off) and then installing the ASP.NET Core hosting bundle as instructed.

I'm not having any luck.
Here's my setup App Pool
Here's my setup Site
I've done everything I know. Does anyone have this same experience and can share a solution?
As always, a big thank you to the experts out there!
UPDATE:
I created a new AppPool with Identity "ApplicationPoolIdentity" setting. The page will run however I need to connect to a SQL Server instance with my own credentials because we use Windows authentication on most of the pages. When I create a new AppPool with my credentials it will not stay running.

Is it possible to remote-connect to an Azure App Service running on Windows with my IIS Manager?
This seems to have been possible according to this blog post by clicking in IIS Manager File -> Connect to a site.
I refer to the steps mentioned in the link shared by you and in the last step I got an error below.
I did some research on it and it looks like managing the App Service from IIS is not supported anymore. I have not got any official link but the below links might give you some information on it.
Microsoft.Web.Configuration.AppHostFileProvider not found after configured Remote IIS Administration for Microsoft Azure Web App
Can no longer manage any Web Apps with IIS Remote Manager - Could not load file or assembly - AppHostFileProvider
I'm not sure for what purpose why you want to. My thoughts is you shouldn't be doing that as it defeat the purpose of PaaS services. Cannot access the iis layer in app service however you can still configure in web.config of your web app.
Hi I have done following steps while hosting my .net core web API in IIS of my laptop. But when I browse the URL I get 404 error.
Sample URL: http://localhost/Myapp/api/user
Help will be much appreciated! If need any further info let me know.
Steps:
Install Install the .NET Core Hosting Bundle 2.2.5
Hosted web api in IIS with defaul 80 port number without any hostname
Created new application pool with No MANAGED CODE as .NET CLR Version.
To host .NET Core Web API in IIS follow below steps:
Publish the Web APIs to Your Local Folder
for example, D:\testcoreapi
Install Microsoft .NET Core Windows Server Hosting Bundle File
ASP.NET Core Module Configuration Reference
Open IIS Create One Application Pool of No Managed Code
Create Web Site to point to the local folder of your published.
Note:
Do not forget to select an application pool which you created before with no managed setting.
If you are still not able to browse the site select your site from connection node in iis.
right click on site and select "Explore" and make sure that you select right folder.

I have a remote Windows 2012 server running IIS 8 from which I am hosting a web application. My local development box is running Visual Studio 2012. Currently I am publishing my app as a web deployment package (.zip), RDP'ing to the production server, copy + pasting to a folder and deploying the application from within IIS. My question is, what changes do I need to make to deploy directly to IIS from Visual Studio 2012 using the web deploy option?
I have tried to follow this guide but it refers to a service URL which I must obtain from my hosting company. I don't have a hosting company, my server is co-located.
I am presented with the following options:
Is the username and password the one I use for the RDP account? I already have Web Deploy 3.0 installed on IIS do I need to enable further settings?
OK I found the solution but it took me a whole day to get it working! Basically the steps are as follows. This is very sketchy but see the detailed guides below which helped me.
Enable the IIS Web Management role feature.
Install Web Deploy 3.0 (or higher). Make sure to customise the install to include the handlers (See notes below). If you're not presented with this option go to add/remove programs, find webdeploy, right click and select "change" option.
In IIS click on the server node and find the "Management Service" icon. Enable remote access and configure a dedicated IIS User for remote deployment (These will be the credentials that will go in the user name and password boxes).
At the site level in IIS assign this user to manage the website.
Make sure port 8172 is open on the web server (you can check this port here).
Try reconnecting from Visual Studio. There was some trial and error here for me but the error messages do link to a MS guide for decoding :)
Even after connecting successfully I had to wrangle with permissions, so my IIS user had sufficient privileges to create the app pool, directories and general file management jobs.
The following links really helped!
Configuring the handler on the web server:
http://www.iis.net/learn/publish/using-web-deploy/configure-the-web-deployment-handler
Connecting via Visual Studio:
http://msdn.microsoft.com/en-us/library/dd465337(v=vs.110).aspx
NOTES:
To ensure the handler is running, login into your IIS server and point your browser to the following URL.
https://<servername>:8172/MsDeploy.axd
F12 to open up the dev tools to see the HTTP response. Also MsDeploy also creates IIS logs in inetpub/logs which should give you some clue if you're having connectivity problems.
I had the same problem and this post was very useful to help me solve the issue. I had anyhow serious troubles while trying to install Web Deploy on my Windows Server 2012. The installation of Web Deploy 3.0 was giving me several errors and it couldn't be completed.
I tried to solve the problem installing "Microsoft Web Platform Installer 5.0" from http://www.microsoft.com/web/downloads/platform.aspx but it didn't solve it.
I thought it was due to Firewall Settings, Authorizations issues, Users without permissions or something like that. Finally I found out it wasn't due to any of the mentioned reasons.
I found the most simple solution and I hope it will help other users too: it was enough to download Web Deploy 3.5 installation directly from Microsoft Website:
http://www.microsoft.com/en-us/download/details.aspx?id=39277
This may sound banal but it solved it. I was able to install "Web Management Service" but not the second needed IIS service "Web Deployment Agent Service".
I am trying to debug a Windows Azure Cloud project locally with Visual Studio 2012 running the Windows Azure SDK 1.7 on a Windows 8 PC with IIS 8 Express. The cloud project includes a Web Role running an ASP.NET MVC 3.0 web project that includes WCF RIA Services that in turn links to a Silverlight project hosted on that web site. When I run the web site directly and do not try to debug the Azure cloud project I am able to access the web site and the Silverlight application and the RIA Services are accessible with absolutely no issues. If however I debug the Azure Cloud project the emulators start up and the web site comes up. I am able to then access the Silverlight application but when it tries to make a request back to the WCF RIA Services Domain Service I receive an error from the IIS Server stating that the domain service is not available. I then try to go directly against the WCF RIA Service endpoint to see if it will come up outside the Silverlight application and again I receive a 404 Not Found response when going to the *.svc endpoint.
I have gone through various searches to try and resolve the issue and I have used Fiddler to ensure the network requests are not having any issues. I have not been able to identify any problems. I also tried turning on WCF tracing to see if any errors comes up, but the trace files are not even updated when I debug through the Azure Cloud project.
After repeatedly getting this behavior I have attempted a complete re-install of Visual Studio 2012 and the Azure 1.7 SDK, but I still get the same behavior. Does anyone have a suggestion of what the issue may be or how I might try and track down the issue, since the WCF tracing is not offering me any additional information?
Strange. Could you try this sample project, which is quickly created with VS2012 on W8 using IIS8 Express, .NET 4.0, MVC3 hosting Domain Service and Silverlight consuming that domain service. Everything works just fine.
If that project runs at your environment fine - then it might be some missconfiguration of your web.config/global.asax file. If that project also fails in your environment - then it might be something very messy with the environment.
My Setup: W2K8-R2 IIS7.5 x64bit servers (app pool is running in 32bit, though)
We have a (.net 4.0) web application that runs under the "ApplicationPoolIdentity". It has "Windows Authentication" enabled. The web app calls a web service on different (older - W2K3 II6) web server (same domain). The web service requires Windows Authentication as well.
On some of our web servers, this works well and I can see that the Web App calls the web service and identifies itself as the machine name for the web server it is running on (as expected). However on other web servers the application will not identify itself when it calls the web service and thus gets a 403 error (this is confirmed by looking at the IIS logs for the web service).
I've compared the web servers that work versus those that don't and I can't find any significant differences. (I compared the ApplicationHost.Config files from both sites and with the exception of a few encryption keys they are identical).
Any thoughts on what could be causing the App Pool Identity on the bad machines to forgo identifying itself? Did we set something up on one web server and miss it on the other?
If not, can someone recommend tools that could be used to track down what's going on?
Thanks for any help.

Summary: Install MS HotFix KB2545850 and learn the details about this bug in KB2672809 which also shows how to reproduce this issue.
An update in case anyone runs into this... We realized that the common thread between servers that worked was that they had been rebooted recently. After rebooting the problem servers, they too started working.
At this point I can't explain what the issue was, but it appears a reboot solved it. I will update if the problem reoccurs.
