Apache and frontpage

I am completely new to this, so some help would be appreciated.
I have Apache running on an internal server, (Win 98SE) hosting an internal
website for staff. The site has been created using Frontpage 2000 and
appears to run OK. However, I want to add forms to the site but when I run
them, I get the response "You have submitted a form or followed a link to a
page that requires a web server and the FrontPage Server Extensions to
function properly. This form or other FrontPage component will work
correctly if you publish this web to a web server that has the FrontPage
Server Extensions installed."

I loaded the files from the "server extension resource kit" on the Office200
CDROM into Progfiles/common files/ ...../serk/1033 but what do I do next?

How do I load the extensions into Apache (or don't I?)

Thanks in advance.

Geoff.
