Following this tutorial appears to be very straight forward! however i have been at it now for 2 days! going over and over everything again and again and --anyway, right i have followed what i believe to be the correct format as suggested in the article (825498)
1:I have created the website as suggested
2:I have saved all the files to the site - in the suggested place.
3:Sometimes when i click on the link it will open the contents of drive C: (file:///C:/?scid=nonsecure.asp).
4:Sometimes when i right click on the file in frontpage 2003 it will open the logon.inc file?
5:Sometimes when i click on the links i will get "Directory Browsing Not Allowed".
6:Sometimes i wish someone could say "this is what you are doing wrong"

please help

I have windows server 2003 and save my files directly as stated in the tutorial.

I have enabled ASP and Server Side Includes on the server (running iis6).

AVG 7 for server: up to date?
What i would like someone to confirm for me is that the code and instructions on the site are correct and work for other people!
I have no other troubles with any other sites on my network- i run 2 machines and both with other sites have no issues.
My experience is probably like a day 1 pupil so i will not try to hide that fact.
What worms or viruses did you have in mind and will take time out to investigate them fully?
