How to enable ASP applications and ASP.Net applications on WSS

On a server running Windows Sharepoint Services (WSS) where WSS has taken over the default web site, ASP applications are disabled by default. Also, ASP.Net applications will not run by default since WSS imposes some serious security restrictions on the web site. See this MS KB article (828810) for details and resolution. Basically you need to set up an excluded path in the Sharepoint Services Administration page.
