I have about a dozen horror stories about being sent on-site to assist a customer who was having a massive production outage, only to discover that they were "smothering" all exceptions in a global handler... (because the hosting platform their components ran in was notorious for generating thousands of useless exceptions) With no logging... But invariably, they would not want log files created in their production environment... So, we would add at least an OutputDebugString() to the catch... prepare a build - then in the production environment we would use the Sysinternals "DebugView" to find out why things were breaking... (And typically - it was a missing dependency or DLL version miss-match from dev to production) Fun times.
