I have been trying to set up my smtp service to allow me to run my website from my pc instead of the expensive hosted option i have at the moment. The web service runs great but i am getting a really confusing error message when i use cdo to send email. When my asp script calls the Send() method, i get the following.... The event class for this subscription is in an invalid partition. I am struggling to comprehend this one and can't find any help on the web anywhere. Don't make me go back to cdonts!!! (actually i would if i could find a copy of the dll anywhere - hint, hint!) Oh, i'm running iis on xp pro.
