We changed SA password. Then every minute from SQL logs and application logs, we can Login failed for user 'sa' Reason: Password did not match that for the login provided. [CLIENT: <named pipe>]
Platform: Window 2008 R2; SQL Server 2008R2 SP2, Enterprise, Mix mode, Dedicated data server
We don's embed SA password in any 3rd party applications. Most application use NT authentication or have their own SQL account to make connection to the SQL Server. We can't find where the error come from. Please help how we resolve the issue.
