your network documentation. This is reliably reproduced by leaving the app open for the night and resuming work in the morning. Since it's a backend server app this is a normal scenario.

Using the previously opened connection to query the database As far as I can tell from experience, client side ADO code is not able to consistently determine if an underlying network connection is actually valid or not. Checking if the database connection is open (in the client code) returns true. However, performing any operations on that connection results in a General network error. The connection pool appears to be able to determine when a connection goes 'bad' so it
