smtpmail send error (Access Denied or Error loading type library/DLL)

I have a strange (but very blocking) result when using the smtpmail
class from an ASPX page :

here is the (very simple !) code...
mail.To = "el@illico. fr"
mail.From = "el@illico. fr"
mail.Subject = "test envoi de mail"
mail.Body = "test envoi de mail"

System.Web.Mail .SmtpMail.SmtpS erver = "localhost"
System.Web.Mail .SmtpMail.Send( mail)

.... and here is the error message :

Error loading type library/DLL.
Exception Details: System.Runtime. InteropServices .COMException: Error
loading type library/DLL.
Stack Trace:

I have this error only on one server, the production one... it works
fine on my dev and test servers. Here are the configs of the 4 servers
windows 2003 server US, framework 1.1, office 2003 with outlook
windows 2003 server US, framework 1.1, office 2003 with outlook
windows 2000 server US, framework 1.1
- PROD2 (doesn't work)
windows 2000 server US, framework 1.1, office 2003 with outlook

I tried to put the ASPNET user in the Administrators group, but it
didn't change anything. I also tried to add an identity
impersonate="tr ue" in the web.config, so that the user is now
IUSR_machine, and the error message is now different :

Access is denied.
Exception Details: System.Unauthor izedAccessExcep tion: Access is

Anyone has an idea ? I have found nothing in the groups nor in the
Microsoft KB... but it seems to be in relation with the CDOSYS

Hi I am writing a ASP.NET web application that must sent some e-mails. I get the exception “Could not access 'CDO.Message' object” when I call SmtpMail.Send.

Hi, I have built an webapp in C# that uses SMTPMail to send mail to users. When I installed it on the prodserver everything worked fine for me, but the users can not send mail. They get Access denied. If I add them to the administrator group of the server everything works fine. I have set <identity impersonate="true"/>
