lخطار در ايجاد پسورد روي administrator

سلام
خواستم روي پوشه administrator روز بگذارم كه با اين خطا مواجه شدم:
Warning:
Due to Frontpage Extensions currently being installed and enabled, password protected directories will not work. If you wish to use this feature instead of Frontpage, please disable the Frontpage extensions.

You can use Frontpage directly to create password protected directories just like you normally can here. Alternatively, you can disable frontpage extensions and still use Frontpage to publish the site design via Webdav or FTP.

لطفاً راهنمايي فرماييد.
