Reply | Quote Answers 1 Sign in to vote State 11 is valid login but server access failure. State=16 means that the incoming user does not have permissions to log into the target database. Also check the default database for that login is online.

If not, do you recognize the IP Address? Is this coming from the Local Server, or a remote system? You can create a trace in SQL Profiler and add the Errors and Warnings event set, and the Audit Login Failed, Audit Login, Audit Logout events. Then remove all other events from the default trace configuration. Then Add the Hostname column, and start the trace. When the login fails again, you will likely see what database it is trying to connect to in an error message, and the hostname that is attempting to login. This should help point you in the direction for what is causing the issue more. Let us know what the trace catches. Also do you have reporting services installed? This is another good point to look at. If it is not installed and running under a service account appropriately this can happen. Look at the following for configuring SSRS: http://www.databasejournal.com/features/mssql/print.php/3683406 If you are not using SSRS and it is installed, try disabling the ser

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 https://social.msdn.microsoft.com/Forums/sqlserver/en-US/bac74bca-9acb-4d33-8615-c37846e140e1/error-18456-severity14-state11?forum=sqldatabaseengine message is similar for most 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 http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx 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 there is no SQL login with that name) or state 8 (if there is also a SQL login with the same name and the password doesn't match). There is also a new state 65 which occurs if you have specified the correct username and contained database, but entered an incorrect password. The way that the authentication process works is, if SQL Server doesn't find your user in the contained database you specifies, it tries again at the server level, then gives up (it won't go check all the other contained databases in case you match there - I hope you agree that this is a good thing). If you don't specify a database in your connection string, then it won't succeed unless - by coincidence - you have a conta
SERVER - Login failed for user . Reason: Token-based server access validation failed August 19, 2015Pinal DaveSQL9 commentsThis is one of the most common error searched on my blog search (http://search.sqlauthority.com) and lately I realized that I have not written http://blog.sqlauthority.com/2015/08/19/sql-server-login-failed-for-user-reason-token-based-server-access-validation-failed-with-an-infrastructure-error/ any blog about the cause of such error and fixing that. Let us learn about how to fix the error login failed.If you ever talk to an SQL Expert about login failed for user, he/she might ask for the state of the message or complete error message. All login failed for user message would have error number 18456 but the state of the message in nt authority the ERRORLOG would tell the exact cause of login failure. It is important to note that SQL Server does not tell the exact state to the client and it would be a state 1 always.Login failed for user ‘sa'.
