kgun makes sense, I don't know asp either.

I'd try checking that you can view the feed in your browser, and if not, check that the feed is enabled perhaps somewhere in phpBB settings. Also check that guests can view the feed. I'm not sure of phpBB group permissions system, it would be what I would try in another forum software first. Then I might experiment with the url/path used in the feed parser. Hope that helps.
