Question

I know that are innumerous posts out there with this problem and solutions, but I think I have tried all of them and I can’t get rid of the 404 error.

I contacted my host provider to get some info.

They told me and I quote:

This site is hosted in IIS 7.

The application pool used by the application ‘xxxx’ is already set to ‘DefaultAppPoolPT_DOTNET40’ which is in .Net framework 4.0, Classic pipeline mode.

For wildcard application mapping in IIS 7, it’s done in the web.config file.

Although they said that is IIS7, when I go to the website I get this headers:

Server:Microsoft-IIS/7.5

But I don’t know if is relevant or not for this case.

As so many others I followed this guide http://msdn.microsoft.com/en-us/library/cc668202.aspx without success. I tried the famous

    <modules runAllManagedModulesForAllRequests="true">

without luck.

.html files and images works fine. .aspx files doesn’t.
I’m just wondering if is a web.config problem or if is IIS that is not configured properly.

Answer 1

After talked once again with the hosting provider they told me that

the application pool user of the application ‘xxxx’ doesn’t have
access to the folder.

After they solved this problem the website was up and running fine.
