404, asp.net 2.0 and IIS

I need to set up a custom 404 page for one of our IIS sites, which I've
done. This works for any URL pointing at this site EXCEPT if it ends with a
.aspx.

If it ends with an .aspx I get a generic 404 error page. I assume any non
aspx request is being handles by IIS, but the aspx requests are actually
being handles by .net

How do I change the default error page that asp.net is redirecting to?

Actually, request handling works like this:

cessing_Basics_Part_1.aspx

IIS Custom Errors only apply to handlers that use it, and not all
handlers use IIS's configuration.

For example, ASP.Net has its own <customErrors> setting for all
requests handled by it.

Ah! That didn't occur to me. There's no actual ASP.net app on this site, but
it's obviously running the framework. I'll add a config file and that should
work. Thanks!

If you have no ASP.Net app, then you can use aspnet_regiis.exe to
remove the ASP.Net bindings from that site, in which case .aspx
becomes unmapped to ASP.Net, so IIS will handle request processing for
that extension and hence send out the custom error you configured in
it.
