If you have an HTML page with VBScript, you really either have a DHTML page (client-side VBScript) or an ASP page (server-side VBScript).
Where did this page come from?
On clue is to look for <% and %> symbols in the code, right at the top. If these aren't there, it isn't ASP.
If it is ASP then it needs to normally be named xxxx.asp and not .htm or .html and it really should be part of a "web" (in FrontPage terms) or an "application" (in InterDev terms).
In reality though it can be dumped into any virtual directory that has scripting enabled. A lot of hack ASP is done this way, with no global.asa or other of the normal trappings of an ASP application.
