It appears your ASP.NET application is making a call to a SQL Server database via a COM (Component Object Model) component, but something in or downstream of that component is failing and causing the request to the database to time out. You're almost certainly going to have to get in touch with some development staff that can debug this issue in particular to determine what component(s) is/are involved, what servers are being contacted, and what intermediate error(s) may be occurring that are causing the failure/timeout. Very difficult to provide much more detail than that at this point based on this stack trace.

EDIT: A true "timeout" could be indicative of something inside a stored procedure that is becoming stuck in an infinite loop (as one possibility). There are myriad other possibilities, so take that as merely one possibility among many.
