Folder persmissions on Windows 2000 machine

Hi There

I am having difficulty with some folder permissions that do not seem to be replicating from the parent folder in Windows 2000.

The situation is that we are hosting a website on this server and when users try to view certain pages on the site it is asking for a username/password which it did not do till this week. I can manually change the settings myself to allow access but shouldn’t need to do this as you will understand.

I have done some reasearch and it points to the Internet Services Manager, I have had a look but dont know where to go.

Your help would be much appreciated
