Hi All, I have an ASP 'Contact Page' which is a form that users can fill in to send the relevant person an email. I have been using the same script for all my websites ever since migrating from CDONTS to CDO. It has worked perfectly - until now. For no reason whatsoever, instead of delivering the mail and sending the user to the finish page, my script is returning an error code '8004020e' for the line where my message is sent. I understand this error code means a problem communicating with the server - however I have tried with multiple servers and have the same problem. I have also tried the script on another machine and it works perfectly. I can only think that this is an IIS problem. The script is functional, the SMTP server is functional - all that's left is IIS. What's really weird though, is that I have made no changes to my server. The last contact email I recieved was on the 6th of this month - now it just doesn't work. Does anyone have any suggestions? Could it be an automatically installed Microsoft patch which has broken something? All suggestions gratefully accepted - i'm at my wits end and have run out of tea bags... Thanks in advance, Jamie
