I have an IIS7.5 web-site, on Windows Server 2008, with an ASP.NET MVC2 web-site deployed to it. The website was built in Visual Studio 2008, targeting .NET 3.5, and IIS 5.1 has been successfully configured to run it as well, for local testing.
However, whenever I try and navigate to a page running in IIS7, I get a 404 error.
I have checked the following things:
There is no corresponding 404 log entry in IIS logs.
Actually, there are 404 entries in the IIS log.
The application pool for the web-site is set to use the Integrated pipeline.
The "customErrors" mode is set to off.
.NET 3.5 SP1 is installed
ASP.NET MVC 2 is installed
I've used MVC Diagnostics to confirm all MVC DLLs are being found.
ASP.NET is enabled in IIS, which we've demonstrated by running the MVC Diagnostics page.
KB 2023146 did highlight that HTTP Redirection was off, so we've turned it on, but no joy.
EDIT
Ok, so we've installed the world's simplest MVC application (the one which is created when you create a new MVC2 project in Visual Studio), and we are still getting 404s on any page we try and access - e.g.
<my_server>/Home/About will generate a 404.
Any ideas will be greatly appreciated!
This is quite often caused by the following missing from the web.config:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
Do you have a problem with just 1 page or the whole site is not working?
A) 1 page
You can use RouteDebugger to verify if the route is matched correctly
B) Whole site
I assume you're using Windows Server - check if ASP.NET is enabled in IIS - it's disabled by default, I believe.
You can use MvcDiagnostics page to check if all dlls are deployed properly.
Are you running in IIS7 integrated mode? Classic mode of IIS7 does not automatically map extensionless URLs to ASP.NET (much like IIS6)
Make sure your Web.config tag is configured correctly.
We finally nailed this issue by exporting the IIS configuration of a working server, and comparing it to ours.
It was a really obscure setting which had been changed from the default.
IIS ROOT → request Filtering → Filename Extensions Tab → Edit Feature Settings → Allow unlisted file name extensions
This should be ticked.
This can be set at the IIS level, or the site-level.
Glad that fixed your problem. Others researching this issue should take note of the extensionless URL hotfix: http://support.microsoft.com/kb/980368
If none of the other solutions here solved your issue, check that you have the
Global.asax
file in your website. This solved the issue for me.
Checkout if KB 2023146 applies to your scenario. Also try requesting directly a controller action: /yoursitename/home/index
Apparently this can have many different causes.
For us, the problem was that the DNS entry was configured for two IP addresses, but the IIS configuration would only listen to one of them. So we got unpredictable results, sometimes it would work, sometimes a few files (css, etc) would not load, and sometimes the whole page would not load.
For me it was all about installing .NET Framework 4.6.1 on the server (my app was targeting that version)
You'll also get this if your bindings aren't correct. If you don't have www or a subdomain it'll return a 404.
I had this problem when running my MVC4 site with an app pool set to ASP.NET 4.0 and the Classic pipeline, even though the extension handlers were set in my web.config and were showing correctly in IIS. The site worked in Integrated Pipeline so I knew it was a configuration issue, but I couldn't nail it down. I finally found that ASP.NET 4 was disabled for the server in the ISAPI and CGI Restrictions settings. I enabled ASP.NET 4.0 and it worked.
In addition to checking if you're running in integrated pipeline mode, make sure your application pool is set to use .NET! I recently ran into this problem, and when I went in to check the app pool settings, I found that somehow it had been set to "No Managed Code." Whoops!
My Hosting company fixed this for me by doing this (I removed the original password value of course).
<system.webServer>
<security>
<authentication>
<anonymousAuthentication password="<password>" />
</authentication>
</security>
</system.webServer>
Typically I encounter this issue when there is a Routing problem. I compare a working vs non-working to resolve it.
Today however I accidentially created a Virtual Directory in IIS.
It has to be an Application, right click on the Virtual Directory (with a folder icon) -> Convert to Application:
Don't use runAllManagedModulesForAllRequests. You want to let IIS handle resources such as images.
<system.webServer> <!-- Rather do NOT use this -->
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
Instead add the MVC routing module
<system.webServer>
<modules>
<remove name="UrlRoutingModule-4.0" />
<add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
</modules>
</system.webServer>

Developing an ASp.NET MVC 5 application. Runs without an issue on the development machine (Windows 7 x86). When I tried to deploy it on IIS 7.5 (Win Server 2008 R2 64 bit) I got 3 errors:
Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive.
I fixed this issue by removing targetFramework="4.5" from
<compilation debug="true" targetFramework="4.5">
The tag contains an invalid value for the 'culture' attribute.
I don't know why but compliant was about the following entry:
<globalization enableClientBasedCulture="true" culture="az-Latn" uiCulture="az-Latn" />
After removing culture="az-Latn" uiCulture="az-Latn" this problem also got solved. But I don't think this is a proper way of solving that, so it'd be good to know the right solution.
Now the third error is the one that's taken all my day. After solving the above two problems now I get the error in the image:
The best solution that seems to work for almost everybody is to add the following entry:
<modules runAllManagedModulesForAllRequests="true" />
But I already have it in the config file. IIS was missing URLRewrite module so I installed it manually.(Don't know if this has anything to do with it though). Didn't help. Enabled 32 bit Applications. Didn't help. What else should I try?
There are two possible solutions
Make sure the application pool that is running your site is set to version 4. It's likely defaulted to v2 which will give you all the errors you mentioned in the question.
Re-register your framework with this command:
C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis -i
I'd also revert those changes you have made (e.g. put the targetFramework attribute back in)
I have an existing MVC4 app that I'm trying to port to Azure for experimental purposes. I right clicked the app project and selected Add Azure Project or whatever. I then configured the Azure project settings as necessary and published to Azure.
After doing so, I can access static content just fine at the deployment url, but none of my controllers are responding - I just get a 404 not found error from IIS. What do I need to do to ensure that Azure starts up the ASP.NET bits so my app works correctly?
I ended up resolving the issue by changing the os family from 1 (Windows 2K8 SP2) to 2 (Windows 2008 R2). I'd love to see some documentation on why this fixes the issue, but for now at least it's a solution.
I had this problem when I tried to host my existing MVC application from my local computer to Azure. Please make sure of the following
Allow to run managed modules in the web.config like below
Remove the extensionless handler configuration like commented below
*<system.webServer><modules runAllManagedModulesForAllRequests="true" />
<validation validateIntegratedModeConfiguration="false"/>
</system.webServer>*
I have an ASP.NET MVC project and I am testing deployment to Windows Azure via the local emulator. I can run the project file fine in the development server but when I build the Azure project and it launches via the emulator I am having an issue with content files not being returned correctly. My internal CSS and JS files are being re-directed to the login page as if the authorization is failing; however I do not see where this auth requirement would be coming from.
Things I have already tried:
I have manually removed all the build files from both project (I have also tried the "clean" action for the solution)
I have tried removing the Azure project all together and creating a new one from the current version of my project.
I have tried clearing the local storage through the Azure storage interface.
I have verified that all my content is marked as "Content" in my ASP.NET project.
I have tried flagging all of my content items as "Copy always"
I have verified that the Static Content optional feature is checked
EDIT: I did a deploy to the web and everything works great there ... this is an emulator issue it appears. Any suggestions with that new bit of info?
You should verify your web.config just to be sure. Do you see something like this?
<system.web>
<authorization>
<deny users="?" />
</authorization>
...
</system.web>
Did you put the [Authorize] attribute on some of your controllers, or your controller base?
If it works in the cloud and in ASP.NET Development Server, I am not very sure why it doesn’t work in emulator. However I don’t think the issue is related to your application. For now, I would like to suggest you to check your IIS settings, such as applicationHost.config. Please see if there’re any authorization settings that may cause this issue(Compute Emulator uses IIS under the hook to host web roles). Please also try to host the site in a local IIS directly and see if the same issue could be encountered. If you can reproduce this issue in IIS as well, I would recommend you to consider to add a “IIS” tag to this thread, so more IIS experts will provide further suggestions.
Best Regards,
Ming Xu.
This thread has been open for a long time so I wanted to close it with what ended up being the solution.
It ended up being a bug with the emulator and the environment being used. As I mentioned, I was able to get it working when deployed. I actually tried this same situation 6 months later after updating to the latest Azure tool set and it worked fine so I am chalking this up to a bug in the emulator that has since been resolved.
I'm trying to deploy a MVC application to a news Server, I have .net framework 4 and ASP.net MVC2 installed. My app pool is assigned to .net 4, integrated mode. But for some reason, the routing is not happening properly. I am getting a 404 error on links and not properly routed to the controller. What am i missing here? Is it might be order of installation of .net framework and IIS?
Your app is probably compiled against .Net Framework Version 2.0. Change your app pool to 2.0 and see if it helps.
Try this :
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
Or try to debug routing
So, if you got a 404 error that is because the global.asax is not being executed.
Check out if the IIS is configured to "Check if the Directory/File exists", cause the IIS is default configured to check first if the request exists on the server ... MVC doesn't use the 'real' path, per se.
Hope it helps ;)
EDIT
Try to log something at the time the routing is working ... I mean when the Route inside the global asax is called and check out if the mapping is called...
My ASP.NET MVC application is within a folder called Stuff within IIS 6.0 webroot folder. So I access my pages as http://localhost/Stuff/Posts. I had EMLAH working while I was using the in-built webserver of Visual Studio. Now when I access http://localhost/Stuff/elmah.axd, I get resource not found error. Can anyone point my mistake here! Here is config file entry,
<add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah"/> //Handler
<add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah"/>
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>
<add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah"/> //Module
Working with IIS7 I found I needed both sections of the web.config populated (system.web AND system.webServer) - see Elmah not working with asp.net site.
Perhaps this is related.
Have you added an ignore *.axd routes in global.asax?
For Elmah, we need to differentiate between two things:
First the http modules doing all the work of error logging, emailing...etc.
Second, the http handlers, displaying the error log page and other pages (rss...etc.)
I was having the same problem of 404 resource not found because I have a weird setup!
on my development machine, (windows 7, iis 7 ) elmah was working like a charm because the application pool was working in the integrated pipeline mode. In the production machine, however, the application was using the managed pipeline and I tried all my best to make elmah work but it was all useless...
I then got the idea of displaying the UI (error log page, rss, error detail,...) using regular aspx pages.
I downloaded the source code, made some changes (sorry Atif, I was forced to do this because I needed the quickest solution) and then in my application , I created a folder under which I created regular aspx pages which inherits from Elmah defined pages.
The page only contains one line (ex: for the detail page: <%# Page Language="C#" Inherits ="Elmah.ErrorDetailPage"%>)
Now, I was able to run Elmah regardless of IIS 6/7 and it is working like a charm.. and It saved me from a big headache of correctly configuring http handlers and troubleshooting its work! additionally, configuring security is much simpler!
I don't know if the community is interested in this solution (If so, I am ready to post my full changes).
Hope that this gives you an idea on how to solve the problem in an alternative way (and if you need the modified dll with complete instructions on how to use it, just tell me!)
In the application pool settings in IIS set Managed Pipelin Mode to Classic if you don't want to change code or the web.config file. Your axd.s will then work as before.
Can you post the rest of your web.config?
Or, if you're comfortable enough, can you just ensure that the httpHandlers and httpModules (NOT handlers and modules) sections are filled in properly in the web.config?
