I am getting a VBScript runtime error "Permission denied" when I excute the send method of a CDONTS object in an ASP script.

Something like:
objMail = CreateObject("CDONTS.Newmail")
'set property values here
'so far no error until
objMail.send

'it doesn't reach this last line
Set objMail = Nothing

Any ideas as to why please?

Thank you.
