We are experiencing intermittent authentication errors "Error: 18456, Severity: 14, State: 10" on a customer's production server. This is a new server that has just been rolled out in the past several months. Rebooting the server appears to make the problem go away. We are using SQL authentication from a separate server that is running IIS. The application always uses the same username and password to connect.
select @@versionMicrosoft SQL Server 2005 - 9.00.2047.00 (X64) Apr 14 2006 01:11:53 Copyright (c) 1988-2005 Microsoft CorporationStandard Edition (64-bit) on Windows NT 5.2 (Build 3790: Service Pack 1)
Sample error from SQL Server errorlog:
DateÃÂ ÃÂ 7/7/2006 10:53:24 AMLogÃÂ ÃÂ SQL Server (Archive #2 - 7/7/2006 12:20:00 PM)SourceÃÂ ÃÂ LogonMessageError: 18456, Severity: 14, State: 10.
MSDN (http://msdn2.microsoft.com/en-us/library/ms366351.aspx) lists various states for this error message but 10 is not included, and it says "Other error states exist and signify an unexpected internal processing error."
Note: This was not a case of a transient error that occurs only when SQL Server is starting up - these errors occurred at a variety of times, two months after the server was last rebooted /ÃÂ SQL Server last restarted.
Thanks for any help you can provide.
