If you are getting error messages in FrontPage relating to server extensions that your site requires, recalculate the FrontPage Hyperlinks:

1.  Open your FrontPage program

2.  Select File -> Open Web

3.  Once your web is opened, select Tools -> Recalculate Hyperlinks

4.  Allow a few minutes to pass and then try re-publishing your files to your site.

 

This will help the features created with Frontpage to successfully work on your pages (links, images, navigation bars, searches, ...etc)
