You need to re register asp.net with IIS. take a look here and follow the instructions. make sure you have the proper framework release ID "C:\Windows\Microsoft.NET\Framework\v1.1.4322 ((Check this directory for the proper release ID))

I think your IIS is not configured to run ASP.NET. The optimal installation sequence would be

(*) Install IIS
(*) Install .NET Framework SDK (appropriate version).

In your case, please go the .NET framework folder (C:/Windows/Microsoft .NET/Framework/v1.1.4322) and run aspnet_regiis -i.

This will configure your IIS to recognized ASP.NET extensions.

What if that still doesn't work for me?

I created a brand new Virtual Machine for just VS 2003 Development.  Installed SQL 2000, IIS 5.1, .NET Framework 1.1, and Visual Studio 2003.  Then, I followed the instructions detailed above, to no avail.

So, I abandoned that VM I created earlier and started on a new one, and installed the software in this order:

Windows XP SP2
IIS
.NET Framework
Visual Studio 2003
SQL 2005

And, I still get the same error message.
