We have setup a .net application developed with .net framework 4.0 using MVC framework and WCF service on a Windows 2003, 32-bit server containing IIS 6 successfully.
However, when the same application is set up on a Win 2008 R2, 64-bit server, we get the following error when the application is accessing the WCF service:
No component for supporting the service was found
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: Castle.MicroKernel.ComponentNotFoundException: No component for supporting the service was found
We have set the flag for Enable 32-bit apps in "Application Pool" to true on the 64-bit server.
I don't think that this is related to WCF itself. ComponentNotFound is thrown by Windsor Castle IoC container and it means that something is wrong with its configuration. So when IoC tries to resolve the type of service it doesn't find related configuration.

I created an asp.net core web api in .Net Core 3.1. It Works successfully when I debugging it using visual studio, o running it in server using exe file. But when I put web api on IIS then service gives following error: One or more errors occurred. (The SSL connection could not be established, see inner exception.) What can be reason? how find reason? how to solve?
I have an Asp.Net Core 3.2 Blazor Webassembly application that has been published to a server running Windows Server 2016 with IIS 10.
After publishing to the server I can browse the login page to the site, However, when I attempt to login which calls a service and signs in with Entity Framework Core 3.1.5.
However when I attempt to call a linq query on the DbContext it seems to fail (This is deduced from log files).
Interestingly, if I remote into the server whilst running a login I get a JIT popup with the following error;
In the Windows System Log can see the following error;
A process serving application pool 'myapppool(domain)(4.0)(pool)' suffered a fatal communication error with the Windows Process Activation Service. The process id was '10188'. The data field contains the error number.
It seems to sometime crashes the apppool as well so if I then refresh the page i get 502 error on the site?
Below is a screen shot of the application pool advanced settings;
The server is running Windows 2016 with Plesk Obsidian installed on it (I'm not sure if this can interfere in any way??)
Does anyone know whats going on here please?
I don’t know what’s going on since I can not reproduce your issue. Here is a workaround.
Please ensure that IIS Application pool’s Advanced Settings has set ”Enable 32-Bit Application” to true.

How to diagnose IIS fatal communication error problem
I have a problem with my site up and running on windows server with IIS
On my local machine everything works fine with Visual Studio 2019.
Its a ASP.NET Core MVC Web Application. When I select publish to the local folder and upload everything to the server and create the website in IIS and try to run, I get this error:
HTTP Error 500.30 - ANCM In-Process Start Failure
on the event viewer I have this error:
Application '/LM/W3SVC/12/ROOT' with physical root 'c:\Webs\mynetcoremvc\' failed to load coreclr. Exception message:
CLR worker thread exited prematurely
//note:
I have another ASP.NET Core API application running on the server without any problem. Both version 3.1.0
Your startup.cs is throwing an error. Need to figure out what it is and it will solve that issue. Mine was due to KeyVault authorization issues.
I have a .net 2.0 app on a win2003 VM that calls a WCF service hosted in IIS7 on a win 2008 VM. After developing the client and service and testing (all was good) I took the opportunity to take a snapshot of both VMs.
I come back to the VMs two weeks later and when I make the WCF call from the client I get a message dialog on the win 2008 server with the caption "Visual Studio Just-In-Time Debugger". The dialog then reads "An unhandled Microsoft .Net Framework exception occurred in w3wp.exe etc.
I take a look at the WCF service log an now see the following in the "WebHeaders" element:
"VsDebuggerCausalityData" AwAAAOEhpa2...lots of AAA
I've tried reverting both VMs to the previous snapshot but get the same problem.
In the WCF service trace file, I can see the logs entries from just before I took the snapshot and the request / response messages look perfect.
Could anyone please advise next step for diag and fix?
Many thanks
Rob.
Try to invoke WCF from wevservice studio. If you can do it , the problem
is in server.
If problem is in server , you can trace where exactly do you fail
Trace can be done using

I am running 32 bit Windows 7 Operation System which has IIS 7.5 installed.
In Visual Studio 2010, I open my solution having the web site project hosting WCF service. I have created an application in the IIS which points to the website project. The web site's bin folder has many assemblies which I need to refer. But those assemblies also have built using .NET 4 on the same computer.
I can browse the WCF service using both HTTP & HTTPS.
However, when i access the service from the test windows application (using the proxy class of the WCF contract), I get the error in question. Everything was working without problem earlier.
Anyone can help to fix the issue?. How to investigate this issue?
Error 0x80040154 means "Class Not Registered", which usually means you're depending on a COM component that hasn't been installed properly on the machine.
Is any of those Assemblies you reference a COM Interop Assembly? If so, find out what it uses and then install the appropriate COM component.
