su un 2003 server, con iis 6, framework 2.0 quando metto delle pagine aspx ricevo il seguente errore...

Server Error in '/' Application.

Source File: \\vmi-fsw-102\wwwroot\www\aonet\aonetnuke.aonet.it\online\Ap p_Code\Global.asax.vb Line: 6

la defaul.aspx contiene una semplice stringa di prova

<script language="C#" runat="server">
public void Page_Load(object sender, EventArgs e) {
Response.Write("Ciaoo!");
}
</script>

per la precisione ho creato un'application pool standard apposita, nelle web service extensions il framework 2.0 e in allowed ed ooviamente nel web site creato ho impostato il framework 2.0... io non capisco proprio cosa sbaglio.....
idee?
grazie a tutti
