Activating Frontpage Extensions on the server
Microsoft Frontpage is a program for editing websites, but it also has the ability to use some extra components that must be installed on the web server (the machine that hosts your files) - the so called Frontpage Extensions.
Notice that it is not necessary to activate Frontpage Extensions on the server just to create, edit and upload web pages - but be aware that these extensions can in some cases put some limitations on the usage of other functions on the server, so it should only be used if you really need them.
It is also important to notice the fact that it is NOT possible to have the Frontpage Extensions activated on the server if you have one or more web applications (osCommerce, PostNuke, Typo3, phpBB, etc.) installed, since Frontpage Extensions controls some of the files that these applications use to protect the contents of confidential folders.
You can upgrade your installation to include this functionality if FrontPage Extensions isn't included in your current web solution.
