IIS 5.0 server won’t display ASP pages

W2K Adv Server with IIS 5.0–I am running this as a web server and can view .htm pages without a problem. However, when I try to view ASP pages, I get “HTTP 500 – Internal server error”. I can view ASP pages from IE from different sites. I only get this when I try to view an ASP page located on this server. ASP is supposed to install when IIS 5.0 is installed. Is there a way to verify this? Why else might this be happening?
