cant debug asp code

Hey eb
After installing microsoft's script debugger,
I configured my default web site and internet explorer
to enable script debugging.

But when stepping into debugging mode in some asp page
i can't see the server side code of it (<%%> ).
Also in the debugger's Running documents window, i only see one branch
of documents, descending from the internet explorer node.
No trace there for the iis side of things..
My default scripting language in the asp page and the iis is JavaScript.
Can this make a diference??
Also the following properties are set on the site's virtual directory:
Script source access is checked and execute permissions are
scripts and executables. Still no change..
Any idea what i may had missed??
I am using w2k sp4 server and iis 5.
TIA
