Problem Scheduled asp page

[gixerino]

Hi I have the ncessità to schedule an ASP page that has as a function of sending an email. The data of this message come from a database.
I created a vbs file that I open the asp page.
If I do a test by clicking on the vbs file locally to the procedure works fine and I get the email with data from the db.

But if I run a scheduled task to plesk, following the instructions, I get the email scheduling operation took place but not the email must be generated from the asp page.

The error in the vbs file is as follows:

"Microsoft VBScript runtime error: Permission denied: 'CreateObject'"

Loggetta is represented by: "InternetExplorer.Application"

This is the code of the VBS file:
' Creo l'oggetto
Dim IE
Set IE = CreateObject("InternetExplorer.Application")

' Rendo invisibile l'operazione
' (Se fosse settato su True si aprirebbe la finestra di explorer
' nel bel mezzo del nostro video)
IE.Visible = False

' Imposto la pagina web da visitare...
' ...cioè la URL dello script che voglio eseguire!
IE.navigate("http://www.fffffdfgdfgg.it/test.asp")

' Chiudo
Set IE = Nothing

Quale potrebbe essere il problema.

Grazie a tutti in anticipo.
