ASP.NET sending Lotus Notes Email

Hi Experts,
 
I have converted all my *.aspx webpages to send email via Lotus Notes email. I have Lotus Notes client installed on the server running on Windows 2003 Server with IIS 6.0. I have web application that update Access database and then trigger an email to recipients. I've tried in development my programs work fine. When migrate the program to production, and trigger an email to recipient I have received the following error:

However, after I rebooted the server, the program works again. Until certain time, then this error occurs again. Can someone please help me to resolve this issue ASAP?
 
Many thanks in advance.
