Troubleshooting Error 18456 I think we've all 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 errors, and the state is always 1). In a few cases, some additional information is sql server error 18456 severity 14 state 8 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 contained user but forget to specify a database name, SQL Server will attempt to authorize you as a SQL login, and you will fail with state 5 (if t

Additionally, http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx there are Ring Buffers entries associated with Login Failures which can be very useful when troubleshooting such issues. This has been blogged about in an earlier blog post here: http://blogs.msdn.com/b/psssql/archive/2008/03/24/how-it-works-sql-server-2005-sp2-security-ring-buffer-ring-buffer-security-error.aspx So, why so much fuss about this error? The above English text even though it is supposed to be helpful can be more of an evil in this case. To explain this simply, the error message is trying to tell you that https://blogs.msdn.microsoft.com/sqlserverfaq/2010/10/27/troubleshooting-specific-login-failed-error-messages/ the security information contained in the user’s token doesn’t have the necessary privileges to grant access to the SQL instance. State 11 corresponds to “Valid login but server access failure” which again points to the same fact that the login is valid but is missing certain security privileges which would grant it access to the instance. The first option that half the SQL world would suggest to you would be to use “Run As Administrator” option and try the same operation from SSMS or SQLCMD. If disabling UAC or if you don’t have UAC enabled, then here is what you should be trying: 1. Look into the SQL Errorlog and verify that that the login failed message for the user has a State 11. You can alternatively verify the state number from the SQL Server default traces as well (available from SQL Server 2005 and above).2. Next look into the Ring Buffers output and find out what was the API that failed. Use the query at the end of the blog post to retrieve the information from the Ring Buffers.3. Check if that login is directly mapped to one of the SQL Server logins by looking into the output of sys.server_principals.4.

I keep getting the standard login failed error and in the error log I'm seeing "Error: 18456, Severity: 14, State: 11." The login is using windows authentication - here's the weird bit. I can login fine from my own machine using the same authentication, just not when I'm on the machine the database is installed on. Any ideas?

When an administrator logs on, this version of Windows creates two separate access tokens for the user: a standard user access token and an administrator access token. The standard user access token contains the same user-specific information as the administrator access token, but the administrative Windows privileges and SIDs have been removed. The standard user access token is used to start applications... When you're logged in locally your administrator token is stripped. Since you granted access to your instance to BUILTIN\Administrators, you are locked out of the instance. When authenticating remotely the administrator token is preserved and you gain access. You would gain access if you'd choose to RunAs\Administrator when starting your application (SSMS?). The solution is to grant yourself access explicitly: create login [domain\you] from windows; exec sp_addsrvrolemember 'domain\you','sysadmin'; share|improve this answer answered Dec 11 '12 at 13:18 Remus Rusanu 206k25268405 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

= 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 SQL server and then an ACCESS was denied to the particular login for a reason. To 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 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, 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 parame
