IIS 6 - "Page Cannot Be Found" When Running .NET Pages

Problem

I have downloaded an ASP.NET application, made sure that the directory property is correct, set the Web Application, the documents contain .aspx and application settings are pointing to correct version of .NET framework.

When I point to the page in the application directory, for example "Default.aspx", the browser comes back and says "Page cannot be found" Even though if you put in index.html file there with some simple test HTML in it, it works.

I have tried to re-install .NET framework...

I have even tried to run C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe /i


Cause

In Windows Server 2003, ASP.NET may be turned off by default, even if you have done bunch of other stuff that I have tried.

Solution

Go back to your computer management and open the Internet Information Service node. You will find one last folder in there that is called Web Service Extensions. You will likely to see that ASP.NET v.2.0.50727 (or whatever the latest version) is in Prohibited state.

As soon as you Allow this, then your pages will run without a problem.

This solution also fixes the problem of ASP.NET tab not appearing in the IIS Web Site properties.

Time took: About 3 hours to find this issue. Whey don't they come up by default!
