reading that blog, one of the blog reader contacted me and told that she is getting state attempting to use nt account name with sql server authentication 6. I thought this error are very common and is important to demystify some of the reasons for the same. I have asked completed error message to assist him. http://stackoverflow.com/questions/2964097/error-18456-state-6-attempting-to-use-an-nt-account-name-with-sql-server-authe Here is the message she shared:Error: 18456, Severity: 14, State: 6.Login failed for user ‘sqlserver2016\sysadmin'.

= 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. http://sql-articles.com/articles/troubleshooting/troubleshooting-login-failed-error-18456/ This message simply denotes that the client call was able to reach the SQL server and then an ACCESS was denied to the particular login for a reason. To figure out the exact http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=110713 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.

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, 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.
