Windows XP Pro and IIS

I have two PCs on an internal LAN. One runs XP HE, the other XP Pro.

I have installed the IIS component on the Pro machine so that I can use it
as a testing ground for websites before publishing them to the world (I use
Frontpage 2003).

Whilst websites on the Pro machine function, whenever I try to publish asp
pages to it, Frontpage states that the server I am publishing to does not
support active server pages (even though the IIS installation installs two
of it's own by default - default.asp and iisstart.asp).

Have I missed out some configuration in the IIS Manager or missed something
during installation of IIS?
