I don't have enough experience to tell you if that's the issue or not but I know enough about the whole Frontpage product to tell you that it was an attempt by Microsoft to completely change (and control) how web pages were developed and displayed. (Thank god it failed!) That site, if I am not mistaken, was actually built in a microsoft office document and the code was generated by a frontpage plugin.
I tested the site mod on a couple of other sites that are .net and had no trouble getting it to work. It has to be something with the underlying markup with that particular page.
Does anyone know what the site mod uses to determine if the url is valid or not? Obviously, it's looking at the underlying code of the page it's trying to get.
