Please assist with common error 2147467259

I'm not sure if I'm even starting at the right place.

We have a web portal that we use to send email TSN Templates. When we press this link, it queries our SQL database but then times out. When we go to our logs to see waht has happened, this is what we get: Can anyone point me in the right direction?

This is an asp.net / enterprise library problem.

But from the message all I can see is that the application is timing out either when connecting to database or when sending email, I cannot tell for sure, with the limited information above.

Thanks
