Sign in to vote This sound like a either a brute force attack, or an application which is not aware of a password chang (if the password was changed the last time). Try to run a network packet sniffer to see who is connecting from with Adresses with the wrong password.Jens K.

Troubleshooting Error 18456 I think we've all https://social.msdn.microsoft.com/Forums/sqlserver/en-US/86d7d044-4ee3-4e1c-b1ff-22b99ee9d6ec/ms-sql-server-error-18456-severity-14-state-8?forum=sqlsecurity dealt with error 18456, whether it be an application unable to access SQL Server, credentials changing over time, or a user who can't type a password correctly. The trick to troubleshooting this error number is that the error message returned to the client or application trying to connect is intentionally vague (the error message is similar for most http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx errors, and the state is always 1). In a few cases, some additional information is included, but for the most part several of these conditions appear the same to the end user. In order to figure out what is really going wrong, you need to have alternative access to the SQL Server and inspect the log for the true state in the error message. I helped our support team just today solve a client's 18456 issues - once we tracked down the error log and saw that it was state 16, it was easy to determine that their login had been set up with a default database that had been detached long ago. In SQL Server 2012, there is a new feature called "contained databases" - I've blogged about it here and here. With this feature comes a new layer of security that may creep onto your radar if you use this functionality: contained user authentication failures. There are a variety of things that can go wrong here. If you connect with a
= 18456 Output: Login failed for user ‘%.*ls'.%.*ls%.*ls This is one of the infamous error message (and number) that most of the DBAs and developers have come across while working on SQL server. This message simply denotes that the client call was able to reach the http://sql-articles.com/articles/troubleshooting/troubleshooting-login-failed-error-18456/ SQL server and then an ACCESS was denied to the particular login for a reason. To http://dba.stackexchange.com/questions/131359/login-failed-for-user-sa-error-18456 figure out the exact reason, this error number 18456 with its STATE number is logged into the SQL server error log file, if SQL server was allowed or configured to capture the failed logins. Configuring SQL server for capturing login failures: By default, SQL server is configured to capture only failed logins but it can be changed to any of the options as mentioned error 18456 in this books online link http://technet.microsoft.com/en-us/library/ms188470.aspx Below figure shows these options to have login failed messages written into error log Accessing Error log: Now that, we know SQL server logs all login failed messages into its error log and windows event viewer but how do I access them? Windows event viewer: GO to start –> Run –> Eventvwr –> open up the application logs, and now we could see the login failed error message with computer name, instance name, error 18456 severity date and time and finally the reason for the login failed SQL Error log: SQL server error log can be viewed from multiple places If we have gained access or can gain access to SQL server with different logon credentials then always use sp_readerrorlog, xp_readerrorlog or use the GUI option of opening up Management node –> SQL server Logs –> View –> SQL server log. Same sample shown above looks like In a case where we cannot gain access to SQL server, then we may use the actual error log path and open the txt file physically from the file system. Use SQL server configuration manager to find the error log path and from there you could open the file. Get the value next to –e parameter and that gives the actual error log file location Typically the error log files are available in install directory for SQL server. SQL server 2005: C:\MSSQL\MSSQL.1\MSSQL\LOG\Errorlog SQL server 2008: C:\MSSQL\MSSQL10.instanceID\MSSQL\Log\Errorlog InstanceID - MSSQLSERVER for default instance and for named instance it’s the name of the instance STATES of 18456 State 1: This is a very generic error message that is sent to the client tools to deliberately hide the nature of the login failure issue. However, the SQL Server error log, a corresponding error contains an error state that maps to an authentication failure condition with its state number.

I started SQL Server instance on Configuration Manager, with Log on as LocalSystem feature, because it is the only option, which isn't caused several error message during instance starting. So after that I've started Management Studio, but it gives error above, when I would like to authenticate SQL Server Authentication method. I have created this user during installation. Why couldn't connect to it? Error: 18456, Severity: 14, State: 8. and State 5. State 5 is for Windows authentication, state 8 is for sa user. I type password correctly, I have tried it several times.
