ASPX throws "404 The resource cannot be found"

Question

I'm deploying a website under a virtual directory using IIS. For some strange reason, Default.html works, but Default.aspx throws a 404.

I have tried these:

• There's another virtual directory that contains an older version of the application and that one just works. I checked the properties of each virtual directory and they looked the same.
• I checked that the root didn't had any extra backslashes

Solution

I think you can use the tool: aspnet_regiis.exe to reinstall script maps for IIS. Remember to completly reset IIS by using command: iisreset.
