>>>I think the upload forms needs to run on a Windows box, If your web host uses Unix or Linux, this feature may not be available.>>>
I was wrong when I said that, that but it does appear the upload component won't run on the Apache web server.

FP2002: Error Message When You Try to Use File Upload
This article was previously published under Q288716
SYMPTOMS
When you try to insert a File Upload form (point to Form on the Insert menu, and then click File Upload), you are not prevented from inserting the File Upload form, and you are not warned when you publish the form.
When you browse to the page that contains the File Upload form, you receive the following string above the form:
[FrontPage File Upload Component]
If you select a file and upload it, you receive the following error message:
Cannot run the FrontPage Server Extensions on this page: "
http://server name/page name"
Also, when you author directly on a Web server, you cannot change the folder properties to allow anonymous uploads from within FrontPage.
CAUSE
Your Web is on an Apache Web server.
The File Upload form does not work with an Apache Web server.This behavior is by design. Allowing anonymous uploads could make the Web server vulnerable to attack; therefore, the anonymous uploads feature is disabled. Otherwise, a user could potentially upload a file that could run malicious code.
