When I use intranet to do a search for any word I get this error

FrontPage Run-Time Component Page
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.
