ASP Pages not displaying.

Running IIS 5 on Win 2000 Pro machine - only for development purposes,
not for live production.

I have never been able to get .ASP pages to display on my machine - I
continually get a 404 error.  (They will work fine if I upload them to
my webhost's machine - therefore isolating the problem to my machine).

I can view HTML pages just fine.  For example, if I use the browser to
visit hollywood movie wallpaper site, it will come up just fine.

If I try http://mymachine/testweb/test.asp, I will get a 404 error (I
know the file is there and I have not typed it incorrectly).

If I browse to the .ASP page in IE and try to open it, it will launch
Front Page 2002.

I'm not sure if this matters, but I did also create a virtual
directory and point it to the directory containing the test.asp page.

I am assuming that I have IIS installed correctly, but I really don't
know for sure.  I never play around with that type of part of my
computer - I'm one of those folks that if it works, don't touch it. 
My only problem seems to be the ASP pages.

I have a huge pile of other websites in my Inetput/wwwroot directory,
so I want to pretty careful to make sure that I don't hurt anything
with my other files.

I read last night on some IIS newsgroups about the Application
Mappings.  I'm wondering if that might be part of the issue.  I
noticed that everything listed was going to 404.dll.  I changed ASP,
CER, CDX and ASA to point to ASP.DLL.

The directory that the test.asp file is in has Read and Scripts
permissions.

I have never been able to get .ASP files to work on my machine.  A
while back I installed "IIS Lockdown" as recommended by Microsoft
Security Website.  However, the ASP pages did not work before this
either.

I would be happy to try and provide any additional information and
would greatly appreciate an answer.  I am quite a novice at this part
of Win 2K, so hand holding would be great.

Thanks for any help you can offer.  I will be at my PC most of the
day, so if you need clarification, I should be pretty quick in
responding.

Best regards,
