What does IIS consist of and how does it work? - asp.net

I have created and configured websites for some time now, but I never really understood what IIS is.
Is it an executable? A group of executables? Some DLLs? What is its relationship with W3wp.exe?
Is this explained anywhere in MSDN?
Thanks.
[EDIT] Ok, it's inetinfo.exe. I have found a detailed description here: http://www.west-wind.com/presentations/howaspnetworks/howaspnetworks.asp

IIS is a server process that hosts web applications in a Windows environment.
Learn about it here: http://www.iis.net/
As I mentioned in the comment above: w3wp.exe is a web process spawned by IIS for each application pool that you have configured and running.

From Wikipedia
Internet Information Services (IIS) –
formerly called Internet Information
Server – is a web server application
and set of feature extension modules
created by Microsoft for use with
Microsoft Windows
It is an exe (InetMgr.exe)

IIS stands for Internet Information Services – a web server for web application, API, web services etc. Current version: 10.0
It is part of operating system and if we are configuring desktop/server for first time then we need to configure in control panel(cmd: appwiz.cpl) –> click Turn windows features on or off –> please checked option “Internet information Services” and next select latest .net framework. It will take few seconds to install. Now you are ready to use IIS. We can access it using inetmgr command in run command. For more, please refer https://bariablogger.in/f/iis-%E2%80%93-a-web-server

IIS7 MVC Routing Not Working

Our company ships an MVC based product (targeting v4.5) which has stopped working on a customer site for what appear to be environmental issues - a build which worked with no problems once upon a time now gives a 403.14 - The Web server is configured to not list the contents of this directory.
.
What I think is happening...
The user accesses http://server/AppName
Because it's an MVC app, the default route (Reports/Index) should be used.
Instead IIS is looking for a default document...
... and, not finding one, it assumes the user wants to list the contents of the directory...
...which is not enabled so it throws a 403.14.
.
What I've tried so far...
Accessing the route directly.. results in 404 error. So I'm pretty
sure IIS doesn't realise it should use routing.
Use aspnet_regiis to register ASP.Net with IIS. This was done from the Framework64 folder since...
OS is 64 bit - Windows Server 2008 (Standard without Hyper-V)
IIS is 64 bit - though Enable 32-Bit Applications is true
Checked AppPool is targeting v4 of the framework - it is.
Changed AppPool mode to Classic - was pretty sure it should be integrated but was worth ruling it out. It is now back to Integrated
Confirmed RunAllManagedModulesForAllRequests is set to true in the web.config.
Checked permission conditions defined in <system.webServer> section of web.config are met - they are.
Created the simplest of MVC applications and deployed it - same problem.
Running the command shell as Administrator unregistered ASP.Net using aspnet_regiis -ua and re-registered using aspnet_regiis -enable -i. We hit a couple of permission problems - and the Temporary ASP.NET Files directory was missing but once they were address we were back to the same error.
Added a simple default.htm - when present, this is served in response to the http://server/AppName request.
I'm clean out of ideas and all google hits suggest some combination of the above - or enabling directory browsing (which I think is just a symptom rather than the root cause).
Also, not sure if it's relevant but the amount of configurable elements available for the application in IIS seems a bit below what I would have expected...
Have you Checked the user the application pool process is running under? I think Your site needs to run with permissions to execute the .net libraries and I've seen this just change for seemingly no reason (probably related to an overzealous update to the system).
You can try with the Enabling directory browsing .
assuming you are under Windows Server 2012 or Windows Server 2012 R2
On the taskbar, click Server Manager.
In Server Manager, click the Manage menu, and then click Add Roles
and Features.
In the Add Roles and Features wizard, click Next. Select the
installation type and click Next. Select the destination server and
click Next.
On the Server Roles page, expand Web Server (IIS), expand Web
Server, expand Common HTTP Features, and then select Directory
Browsing. Click Next.
On the Select features page, click Next. On the Confirm installation
selections page, click Install. On the Results page, click Close.
if you using the Windows PC try this in your command prompt as follows:
go to C:\Program Files\IIS Express
then press Enter:appcmd set config
/section:system.webServer/directoryBrowse /enabled

SQL Server Reporting Services creates a folder called Reports by
default if you install it on IIS. If you install SQL 2008 then
Reporting Services doesn't need to use IIS and instead will try to
reserve the URL with the HTTP.Sys service.
I believe this is the cause of the conflict you are seeing. What you
could try is changing the URL that Reporting Services uses via the SQL
Server Configuration Wizard.
Also I found that
Report Manager of SQL Server can use reports path http://<server name>/reports

I think the problem is IIS features that are not installed yet. I have met this kind of problem frequently in Windows Pro. Make sure to turn on every feature under Internet Information Service -> World Wide Services because by default IIS is configured to use WebForms. So there might be some features that not installed yet to use MVC, especially ISAPI filters. In my case, that was the solution. I hope it helps.
Something similar i encountered using VS 2017 & ASP.NET MVC.
Was working on the project for long with no problems at all but suddenly the routing started misbehaving & stopped working.
So I changed the Port in Project Properties Page & it started working.
I really don't know what is the relation between a port & MVC routing modules. Someone else can enlighten if at all this helps.
I had the same problem and I just created an application pool out of the Default Web Site in IIS and stoped the default web site. With that difference you will not have the application pool's path
I know it's been a long time since this question but i've had the same problema recently. I've tried every single configuration, just like #amcdermott did, but the only action that solve the problem was reinstalling .NET Framework.
My app was built under .NET Framework 4.5.2. The application server had the version 4.6.1 and 4.5.2 installed. So, i uninstalled all framework versions and installed the one that i needed.
Please, make sure that no other applications use superior versions of .NET Framework if you going to try this solution.
Here are some quote I find on Microsoft official site which I think may help:
For site administrators
This problem occurs because the Web site does not have the Directory Browsing feature enabled, and the default document is not configured. To resolve this problem, use one of the following methods:
Method 1: Enable the Directory Browsing feature in IIS (Recommended)
To resolve this problem, follow these steps:
Start IIS Manager. To do this, click Start, click Run, type inetmgr.exe, and then click OK.
In IIS Manager, expand server name, expand Web sites, and then click the website that you want to modify.
In the Features view, double-click Directory Browsing.
In the Actions pane, click Enable.
Method 2: Add a default document
To resolve this problem, follow these steps:
Start IIS Manager. To do this, click Start, click Run, type inetmgr.exe, and then click OK.
In IIS Manager, expand server name, expand Web sites, and then click the website that you want to modify.
In the Features view, double-click Default Document.
In the Actions pane, click Enable.
In the File Name box, type the name of the default document, and then click OK.
Method 3: Enable the Directory Browsing feature in IIS Express
Note This method is for the web developers who experience the issue when they use IIS Express.
To do this, follow these steps:
Open a command prompt, and then go to the IIS Express folder on your computer. For example, go to the following folder in a command prompt:
C:\Program Files\IIS Express
Type the following command, and then press Enter:
appcmd set config /section:directoryBrowse /enabled:true

Missing Web Management Service on IIS (WIN8)

I have seen this asked here before, but none of the other posts solved my issue, so here goes nothing.
We are attempting to use Web Deploy on IIS to automatically deploy our application to a test environment. The idea, besides bettering our deployment process, is to allow Jenkins to deploy our application to IIS and run a few automated tests.
For this we are attempting to use MSBuild along with a deployment profile on our web app. The IIS lies on a Win8 virtual machine, where we try to run MSBuild and it fails because the Web Management Service is not up, and it doesn't show anywhere on the IIS management software.
I have the Web Deploy feature installed, as I have seen from Web Platform Installer, but the Web Management Service icon is nowhere to be found. I have found and started the service manually on the Windows Services configuration, but that doesn't seem to have helped either.
A few other observations:
"IIS: Management Services" item doesn't seem to show up on my Web Platform Installer;
I tried changing my installation (under Windows' Add an remove programs) to include web management, id didn't help
I enabled IIS' Web Management on Windows' "Add and remove features" settings. Also nothing shows up on my manager.
My Windows language is set to Portuguese. I may have missed the config due to bad translation, but that's unlikely.
So, how do I get the service to run so I can configure it on my IIS and finally deploy my application?
Client OSs doesn't come with Web Management Service. You cannot set up remote publishing using Web Deploy for a site that is hosted in IIS on Windows 8.0 or 8.1. You need server OS for same.

How to configure Web Deploy publishing feature on IIS so developer can publish?

I control a server running IIS 8 on Windows Server 2012. I want to publish a few basic asp.net websites with the Publish option in Visual Studio 2012. There are no good/current Microsoft articles on the server configuration steps.
1) What exactly do I need to do on the server? I don't see any "web deploy" role option under the various IIS roles. I have read of some people downloading and installing "Web Deploy 3.0" from Microsoft but that file is one year old and it seems strange that I would have to download another file to use a promoted IIS file deployment option. If you are using IIS7 or IIS7.5 instead of IIS8 like me, please feel free to reply what YOU do, but let me know what version you are using.
2) Is the authentication process encrypted? For example, FTP would send passwords in plain text. FTP over SSL doesn't but setting up even a self-issued SSL cert is annoying just to get secure authentication. So what about Web Deploy? Is it safe or no?
3) Must I open port 8172 on the server's firewall? Microsoft's documentation says I "might need to".
4) On the Visual Studio side, it wants an account for authentication. Is this a Windows account on the server? Should I then right click the IIS website folder on the server and add this user there or is there some other preferred way of mapping users to websites? If so, what rights are required?
Please answer any or all of the above but please focus on the server side configuration and not the client (visual studio). Please don't suggest FTP as I am truly wanting to try Web Deploy. I am adding an IIS 7.5 tag too since some of the answers may be the same as for IIS 8.
It appears that one must still download the Web Deploy extension. Also, Version 3.5 is now available.
To download on a server, default IE security rules will require you add something like http://*.microsoft.com as a trusted site else you can't download the installer.
The whole package is rather large in its purpose and covers many deployment/backup/transfer type scenarios for IIS. So, when you install it, it turns into "Web Platform Installer 4.6" and installs roughly 10 prerequisites in addition to Web Deploy 3.5. Those prerequisites covers CLR Types, SQL Server framework (even if you don't have SQL Server installed), SQL Server shared management objects, etc. I did check afterwards if all these items are uninstallable through control panel (in case I changed my mind about web deploy) and they are there.
Finally, to configure web deploy on a site, I found this document:
http://www.iis.net/learn/publish/using-web-deploy/configure-the-web-deployment-handler
To find more information about this, google "web deployment handler".
It also does appear that you can configure secure authentication, which is the main reason I went down this Web Deploy publishing path instead of using plain clear-text FTP. However, http://www.iis.net/learn/publish/using-web-deploy/introduction-to-web-deploy says
Web Deploy is secure. Web Deploy supports transfer over HTTPS. Note that variants of FTP such as SFTP and FTPS are also secure.
I'm not sure if this means I will have to use an SSL certificate anyway. I was hoping Web Deploy provided more authentication options that were both secure and didn't need a certificate.
The answer marked correct pointed me in the right direction to publish a web site from Visual Studio 2013 to Server 2012. The Validate Connection button kept stating check Web Management service is installed.
As of April 2014 these simple steps work:
Install Web Deploy

In Powershell:

Create a new non-admin user
Once your user is created, we need
to grant it permission to deploy the site. Right click on your
website and select “Configure for Web Deploy Publishing…” from the
“Deploy” sub menu

Install ASP.Net State Service (2.0 or later) without IIS?

For a server farm, I would like to install the ASP.Net State Service on a non-web server to share with all the web servers. Is it possible to install the ASP.Net State Service standalone without having IIS installed on its server? If so, how?
According to this blog entry, Enabling ASP.NET Session State without Installing IIS, the answer is yes.
First, you need to make sure the ASP.NET State Service is installed on the computer. (Of course you'll need to have the .NET Framework installed on this computer.) Go to the Services section in the Administration Tools and locate the ASP.NET State Service item. If it's not there, drop to the command line, navigate to %WINDIR%\Microsoft.Net\Framework\*version*\ and enter:
aspnet_regiis -i
Finally, you'll need to allow remote connections to this server. Go to the Registry and set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection to 1.
Happy Programming!
Please note that I have not tried these steps myself; rather, I am summarizing the discussion from the Enabling ASP.NET Session State without Installing IIS blog entry I cited at the start of this answer...

Why is IIS not serving aspx pages?

I'm deploying an ASP.NET application to Windows Server 2003 under IIS
IIS is serving html pages fine but I get a page not found when I try and serve IIS pages
You may need to "register" IIS for ASP.NET applications. As an administrator, run the command "%systemroot%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -i". In addition, you may need to convert your web site to an application through the IIS management console.
By default, IIS has ASP support disabled in IIS6.
A server running a member of the Microsoft® Windows® Server 2003 family supports application server functionality, with Microsoft ASP.NET as an option that you can enable when configuring the application server role. To deploy ASP.NET Web applications to a production server, you must be sure to enable the ASP.NET and Internet Information Services (IIS) roles on the production server before you distribute the application.
See here for instructions to enable it:
http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/9fc367dd-5830-4ba3-a3c9-f84aa08edffa.mspx?mfr=true
Other possible reason could be Web Service Extensions, where ASP.NET version could have been disabled. My other post here explains steps to solve this.
Make sure the right .NET framework is installed properly
Make sure the ASP.NET extension is enabled
Under website properties, ASP.NET tab, make sure the right version is set.
After having this same issue and trying all of the above without any luck. We reinstalled SP2 for Windows 2003 and this resolved our issue. I too have seen this problem resolved a few times with the other answers. Most of the time just reinstalling .Net 2.0 resolves the issue but not this time.
For future reference, this could also be the issue:
IIS on a Windows Server 64-bit can only to run in either 32 or 64 bit mode.
In short you need to:
1) run adsutil.vbs to enable 32 bit asp.net apps on win 64
2) re-register IIS calling aspnet_regiis.exe
3) re-open IIS Manager, go into Web service extension list and ensure ASP.Net version {2/4.xxx} (32-bit) is set to Allowed
(You might need to do Steps 2 and 3 for both Framework 2.0 and 4.0 if you want to run asp.net apps on both versions)
Full details are in the following link: http://support.microsoft.com/kb/894435
Another future reference in case this is helpful to anyone who used a similar path to mine.
My back end for the ASP.NET app was MySql not Sql Server, which for me meant having a mysql connector, the reason my IIS was not serving the .aspx file is because on my development environment I was using a different version of the MySql connector than the one installed on my production environment, I updated the MySql connector on the production server to match the version Im using on the development environment and it worked great.
