>From the "General Information" section:

What is the Local Machine zone lockdown?
In Windows XP Service Pack 2, all local files and content that are processed
by Internet Explorer has additional security applied to it in the Local
Machine zone. This feature restricts HTML in the Local Machine zone. This
feature also restricts HTML that is hosted in Internet Explorer. These
restrictions help mitigate attacks where the Local Machine zone is used as
an attack vector to load malicious HTML code.

Because of this change, ActiveX script in local HTML pages that are viewed
inside Internet Explorer will not run. Also, script in local HTML pages that
are viewed inside Internet Explorer prompts the user for permission to run.

For how to change the local machine zone security settings, see this
article:

Internet Explorer
