Problema al Subir PDF

[Esfinge02]

buenas tengo un problema, y no se cual es ya que esta rutina funciona ala perfección pero por alguna razón no puedo subir archivos en PDF....

Código:

<%response.buffer=true
Func = Request("Func")
if isempty(Func) Then
Func = 1
End if
Select Case Func
Case 1
%>

<form enctype="multipart/form-data" action="ventanillaunicadoc.asp?func=2&idDoc=<%=idDOc%>" method="POST" id="form1" name="form1"> 
                <table align="center">
                <tr> 
                <td><font color="#330066" size="2">Pulsa en el botón examinar y elige el archivo 
                de tu ordenador.</font></td>
                </tr>
                <tr> 
                <td><font color="#330066" size="2">Luego pulsa el botón subir.</font></td>
                </tr>
                <tr> 
                <td><StrONG><font color="#330066" size="2">Nombre del archivo...</font></StrONG></td>
                </tr>
                <tr> 
                <td> <font size="2"> 
                <INPUT NAME=File1 SIZE=30 TYPE=file>
                <br />
                </font></td>
                </tr>
                <tr> 
                <td align=left> 
                <INPUT type="submit" value="Subir">
                </td>
                </tr>
                <tr> 
                <td><font color="#330066" size="2">NOTA: Espera, recibirás una notificación
