Disable drive list using ASP Code

Hi,

I have a web server runnig IIS 6.0 and need to block that a user can list
my drives and navigate in folders using an ASP code.

The example is in http://paludo.no-ip.org:9090/teste/drive.asp

I know that it can be done disabling FileSystemObeject by running the
following regsvr32 scrrun.dll /u.

But I can´t do this, some sites uses this component.

I know that it can be done without disabling FileSystemObject, but don´t
know how.

Anyone can help me please?

Thanks,

Lisandro
