In SQL Server, there are error few messages which can be caused due to multiple reasons. One of the famous example is “Login Failed for User” error message. If you have seen this earlier, you would know that this message can come due to incorrect user name, incorrect password, incorrect database and many more other reasons. Whenever I see login failed, I look at SQL Server ERRORLOG to see the exact cause.
