CDONTS SMTP Email Problem

Hello All,

We are sending out emails from a web application (when someone registers) on a standalone web server running Windows 2000 using the built in IIS SMTP and CDONTS. Most mail goes through fine but sometimes the event logs show Error 4000 - Unable to bind to the destination server in DNS or Unable to successfuly connect to the remote server. Would like to get these cleared up asap.

Thanks in advance.
