You cannot access files that are outside the virtual directory using a link. Otherwise, it will be very easy for hackers to locate files of other sites on their web host.
You need to put PDF file in a directory within the physical path of your virtual directory. Or access it through its http address. Please see the modified code below.

<%@language="vbscript"%>
<% option explicit %>
<% dim strPDFfile
strPDFfile = "www.yoursite.com/pdf/test.pdf"
%>
<html>
<body>
<br /><a href="#" onclick="window.open('http://<%=strPDFfile%>','Pdf_form','height=450px,width=70 0px');">PDF FORM</a>
</body>
</html>

Please see some of the double quotes were replaced by me with single quote (to avoid
JS errors).
