IIS WPI ARR loadbalancer 503 - iis

I'm running a test infrastructure with windows server 2019, 2022 having IIS 10 - Default IIS site.
Also the infrastructure contains windows server 2016 as IIS ARR Load balancing and two windows server 2012 for DNS and AD.
The 2016 server is performing the redirection completely fine. Roundrobin is functioning properly.
I have made one of the 2012 server to do the same. Installed IIS, Web Platform Installer and enabled Server farm with ARR.
when i browse the URL of 2012 , i'm getting 503 error, APPPool stops and Error of Rewrite.dll data is error in event viewer.
tried the same in another new windows server 2012 and 2016. 2016 working properly. 2012 same issue.
Anyidea ?

Blazor - Internal Server Error when running in IIS windows server 2012

When I run my Blazor WASM locally on IIS it works perfectly. But when I do it in a windows server 2012 R2 and I call it from my computer it gets stuck at "loading..." and I get a "500 (Internal Server Error)" for blazor.webassembly and blazor.boot.json
I cannot test it directly on the server since it has only internet explorer which is not compatible.
chrome developer tools printscreen
I have followed different tutorials, so I have already installed "URL rewrite" and the "Windows Hosting Bundle Installer".
Any idea what to try next? I have been searching in forums for two days now.

IIS HTTP Error 503 after in place upgrade from 2008 R2 to 2012 R2

I recently upgraded one of our application servers from Server 2008 R2 to Server 2012 R2. Everything seems to be working fine except for our little Intranet. When trying to get to it, you are immediately greeted with Error 503 Service is unavailable.
I did some troubleshooting but nothing has seemed to helped. I made sure the app pool associated with the website is running and double checked the identity. (It's using ApplicaionPoolIdentity). What else can I try? Thanks all!
It turns out the the application pool that our intranet runs from was set to use .NET CLR Version 1.1 instead of version 2.0. After switching to version 2.0 and recycling/refreshing the site, the intranet came right up. Thanks all!

SignalR - works on Cassini an IIS Express but not on Windows 2008 with IIS 7.0

We've got SignalR running on a Silverlight 5 client.
It is working on our local machines under both cassini and IIS Express, but it isn't when we deploy the app to our dev server, which runs Windows 2008 Server and IIS 7.0
We don't see any errors on the logs, just the notifications not coming through to the client.
Any ideas? We have rerun the aspnet_regiis tool and also added thr web.config settings recommended in another posts with no success.
Thanks.

Sink on IIS SMTP Windows Server 2008 / 2008R2

I need help. I wrote simple sink by sample in http://msdn.microsoft.com/en-us/library/ms998610.aspx. On IIS Smtp Windows server 2003 it work fine. But on IIS Smtp Windows Server 2008 or 2008R2 it don't work. I try other sample from Internet. None of them don't work on IIS Smtp Windows Server 2008 / 2008R2. Any idea?
Windows Server 2008 has a newer version of IIS that has full integration with ASP.NET. This is the default mode. You can switch back to the older (ASAPI ASP.NET) by changing the application pool in IIS from "default" to "classic". That should make your app run like it does in Server 2003.
Without seeing more code and details, that's the only thing I can suggest.

SQL ReportServer 2005 on Win Server 2008 & IIS7 gets "unable to load client print control"

I have SQL Reporting Services 2005 running on a Win 2008 server with IIS7. SQL and RS have all of the latest patches applied (as of 11/19/2009). When I access a report through Report Manager on the same server or ReportViewer on a different IIS server I can not print. I get the "unable to load client print control".
This occurs with IE6, 7 and 8. All clients are running with administrative rights. I do get prompted to download the component which seems to occur but then I get the above message.
This same configuration works fine in a test environment, the only difference is the SQL and IIS servers are running Win 2003.
TIA
John
The issue has been resolved through applying the latest service packs and any hotfix rollups that were available on 11/21/2009 (SQL server 2005 running on Win 2008)
