Reading NTFS file permission from ASP page (Pls Pls Pls help me)

Hi
I'm developing an intranet site using ASP. The objective of the site is to list only those files to which user has somekind of access permission (read, write, delete etc). The user will log on to the site using basic authentication of IIS.

I'm using NT 4.0

Can anyone help me?

I'm desperately looking for Frans C (that's his screen name in this forum). He has provided wonderful code to read ACL for a file . But his code reads ACL if the user logs on to the NT server locally. As I'm using ASP so I need to read ACL for whoever sends request through ASP page. If you want to review Frans's code, here is the URL

Thanks in advance
