HTTP Error 404.17 - Not Found (.Net 4) - iis

I've just got a new server setup on Windows 2008 Web edition. I'm trying to set the first asp.net 4 application up on it but am having nothing but problems.
The latest is that I'm getting the 404.17 error, which says "the requested content appears to be script and will not be served by the static file handler.".
I've done a lot of research on google but most suggestions seem to be to run aspnet_regiis -i to install asp.net 4. I've done this several times both on the Framework and Framework64 folders, but with no success.
I tried changing from the default application pool to a .net4 application pool, which appeared to work at first and I instead got a server error to do with permissions. I fixed that, and immediately the 404.17 error returned.
Other suggestions I've read say to go into the "turn windows features on and off" and make sure .net 4 is selected there under IIS. However on this server clicking "turn windows features on and off" takes me to the standard windows 2008 server manager. I click "add features" there, and only ".NET Framework 3.0 Features (Installed)" is listed and selected. .NET 4 isn't shown there, yet it is selectable through the application pools.
What else can I try to get the website running as I'm at a complete loss now. Its annoying because my old server was easy to manage - I did it all through the server itself without a control panel (Windows 2003), now on my new server I have to manage most of it through Plesk because there is no dns.
Any help would be much appreciated.

I too had the same problem but solved it with simple solution. My program was in framework 4.0 but in application pool was mapped to framework 2.0.
Just changed the frame work in application pool to 4.0.
It worked.

I've finally figured out the problem, and it was to do with Plesk itself.
After delving through some of the thousands of links throughout the plesk control panel I found a page for "Website Scripting and Security". Under there it was set to .NET 2.0. However, even though I'd installed .NET 4 on the server, Plesk didn't know about it. Although the application pool I'd set the website to run under through IIS was .NET 4, it still wouldn't work for some reason.
I then found another page under "tools and settings" for server components, and on that page is a refresh button. Hit that and it suddenly realised that .NET 4 was installed, went back to the website scripting and security page, selected .NET 4, and hey presto, I got a server error (never have I been so glad to see a server error).
I then just had to give the application pool identity read access to the web folder, and the website worked.
I wish I'd paid an extra £15 per month for Windows 2008 Standard edition now so I could manage it all manually without Plesk.

Ensure that you are running this application under a Virtual Directory, also ensure that your IIS has ASP, ASP.Net, ISAPI Extensions And Filters, Static Content installed.

Change the .net framework from 'plesk' panel:
go to Domains
select then domain
Go to 'Domain and Websites & Domains'
Hide Advanced Operations
Go to 'Asp.net Settings'
Go to 'Change Version'
select 4.0
If you don't have the 4.0 option then you must install the framework on your server first.

Page keeps loading forever

Im using IIS 8.5 on Windows Server 2012 R2 so I add my Web Api but when I try to view the site it stays in a loading state like this:
Do not show any message or error just stays loading, I think that i miss some configuration or feature in my IIS but I don't know which one.
Edit: I use .Net framework, it is a REST .net web api like this reference, the IIS have installed .Net versions 3.5 and 4.5, it's IIS not the express and the default IIS website runs fine.
I would really appreciate any help.
Try to reduce the timeout settings to a minimum level, say 10 seconds.
See if it throws a Timeout error.
Without much information from your side its hard to judge.
Perhaps it could be an external service you are trying to access(Web service) or a DB connection?
Please check if the application pool you assigned to your solutions runs under the correct version of .net framework and in integrated mode. I had similar issues when trying to run an mvc app in classic mode. Check this out.
EDIT 1 - Reconfiguring IIS
If problems persists then try the ASP.NET IIS Registration tool. Execute the followig command as administrator:
aspnet_regiis -i
At the end of this post the different locations for aspnet_regiis are described. You should select a .NET Framework version corresponding to that of your project, run aspnet_regiis and assign the proper application pool to your app.

ColdFusion10 Developer and Windows7 (IIS7.5)

I am trying to learn ColdFusion and have installed the developer edition (CF10) on my Win7 computer and this brings up the localhost administrator page correctly but I have a test helloworld.cfm file in inetpub/wwwroot and when I try & access this with localhost/helloworld.cfm windows opens a dialogue box saying what program should open this .cfm file?
(in IIS Mime type there is none for .cfm & when I tried to add one it didn't work...).
Several posts on the internet say ensure IIS has CGI enabled and ISAPI Extensions
IIS Metabase and IIS 6 configuration compatibility which I have.
I'm not sure what is wrong here-can anyone advise me clearly & simply if I can view and use .cfm in IIS & how?
We know IIS is the problem because your administrator works, so CF is running correctly.
What I do is the following
create a site in IIS, just basic. no setting changes
install coldfusion 10
During install coldfusion will ask me if it has to configure all current IIS sites
if you let it do that, it should all work like a charm.
Did you do it like this?
I would uninstall and re-install as something must have gone wrong connecting IIS to COldFusion
CF10 does not require the IIS 6 compatibility. If you don't need that for any other web technology connections, then remove that. You do need CGI, .Net Extensibility, ASP.NET, ISAPI Extensions and ISAPI Filters. I believe the connector configurator for ColdFusion especially uses the .Net Extensibilty to "wire things up".

Running ASP Classic on IIS 7.5

I need to do some work on an old ASP Classic site, so I’m trying to host it on my IIS, but when I try load a page I get:
An error occurred on the server when processing the URL. Please contact the system administrator.
If you are the system administrator please click here to find out more about this error.
When I follow the link, it takes me to a Microsoft site and talks about running ASP Classic on IIS 7, but none of the pages help and nothing I found on Google will get it to work. I have all the elements under turn Windows features on and off - IIS - WWW services - app dev features.
This was bugging me earlier today and it turned out I had an error in my script.
This assumes you have installed the ASP/ISAPI extensions via the Control Panel's "Add/Remove Windows Features."
By default, errors will not be sent to the browser. To enable sending errors to the browser, go to the site in your IIS manager. Double click the ASP icon and expand "Debugging Properties." Set "Send Errors to Browser" to True.
I had this same problem and it turns out you need to set application pool to classic .net for it to work.

HTTP Error 404.3-Not Found in IIS 7.5

I'm using IIS 7.5 on Windows Server 2008 R2 x64 Enterprise Edition. In the project we have developed with ASP.NET 4.0 we used WCF Service. But it doesn't run over domain when the software is running from local computer. Otherwise, I am getting the following error:
HTTP Error 404.3-Not Found
The page you are requesting cannot be served because of the extension
configuration. If the page is script, add a handler. If the file should
be downloaded, add a MIME map.
You should install IIS sub components from
Control Panel -> Programs and Features -> Turn Windows features on or off
Internet Information Services has subsection World Wide Web Services / Application Development Features
There you must check ASP.NET (.NET Extensibility, ISAPI Extensions, ISAPI Filters will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.
Run from cmd:
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir
Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.
Also, look at this answer.
In my case, along with Mekanik's suggestions, I was receiving this error in Windows Server 2012 and I had to tick "HTTP Activation" in "Add Role Services".
In windows server 2012, even after installing asp.net you might run into this issue.
Check for "Http activation" feature. This feature is present under Web services as well.
Make sure you add the above and everything should be awesome for you !!!
I was having trouble accessing wcf service hosted locally in IIS. Running aspnet_regiis.exe -i wasn't working.
However, I fortunately came across the following:
Rahul's blog
which informs that servicemodelreg also needs to be run:
Run Visual Studio 2008 Command Prompt as “Administrator”.
Navigate to C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation.
Run this command servicemodelreg –i.

How to register ASP.NET 2.0 to web server(IIS7)?

I have a web-page application already created, but when I open it in visual studio 2008, it says there that:
ASP.NET 2.0 has not been registered on the Web Server. You need to
manually configure you Web server for ASP.NET 2.0 in order for your
site to run correctly.
I'm using asp.net 2.0, IIS7 and running on vista home premium.
How to register ASP.NET 2.0 to my web server(IIS7)?
ASP .NET 2.0:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir
ASP .NET 4.0:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir
Run Command Prompt as Administrator to avoid the ...requested operation requires elevation error
aspnet_regiis.exe should no longer be used with IIS7 to install ASP.NET
Open Control Panel
Programs\Turn Windows Features on or off
Internet Information Services
World Wide Web Services
Application development Features
ASP.Net <== check mark here
If anyone like me is still unable to register ASP.NET with IIS.
You just need to run these three commands one by one in command prompt
cd c:\windows\Microsoft.Net\Framework\v2.0.50727
after that, Run
aspnet_regiis.exe -i -enable
and Finally Reset IIS
iisreset
Hope it helps the person in need... cheers!
If you installed IIS after the .Net framework you can solve the porblem by re-installing the .Net framework. Part of its install detects whether IIS is present and updates IIS accordingly.
Open Control Panel
- Programs
- Turn Windows Features on or off
expand - Internet Information Services
expand - World Wide Web Services
expand - Application development Features
check - ASP.Net
Its advisable you check other feature to avoid future problem that might not give direct error messages

The system I was working on is Windows Server 2008 Standard with IIS 7 (I guess that my experience will apply for all Windows systems of the same age).
Running
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir
SEEMED to work, as
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -lv
showed the .Net framework v4 registered with IIS.
But, running the same for .Net v2, namely
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -ir
did NOT result in
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -lv
showing the framework registered.
(And, for me, the installer for Kofax Capture Network Server was still missing ASP.NET.)
The solution was:
Open Server Manager
Go to Roles/Web Server (IIS)
Push Add Role Services
check ASP.NET under Application Development (and press Install)
After that, aspnet_regiis.exe -lv (either version) shows the framework registered.
(And the Kofax installer was also happy and worked.)
I got it resolved by doing Repir on .NET framework Extended, in Add/Remove program ;
Using win2008R2, .NET framework 4.0
