SQL Server connection timed out.
This error message is returned from DB-Library when the query time-out setting for the application's connection to SQL Server is too low. The query is terminated when it takes longer to complete than the time allocated.
Check the application for configuration settings, and increase the query time-out setting. If this is a custom application, you can adjust the query time-out setting by using the bdsettime() function in C or the SqlSetTime% function in Visual Basic.
