Sql Error 18456
few times during the work day, seemingly at random, I am getting a log entry of "Login failed for user 'OurDomain\mfreeman'. [CLIENT: 192.168.0.48]". This is paired with a log entry of "Error: 18456, Severity: 14, State: 16." at the same time. This is my own login (which has the sysadmin role in the instance), and it is coming from my workstation. I captured an example of this with Profiler and found that it is for the master error 18456 sql server database (which is online and not having any troubles -- I can run queries against it in SSMS just fine) and is coming from an ApplicationName of ".Net SqlClient" (which could be anything). I am not getting any visible errors in any applcations (such as VS2012 with SSDT and Report Builder) or SSMS add-ins that I am using (ApexSQL Complete, SSMS Tools, Dell Spotlight Essentials). Is there any way to find out more specifically what might be attempting the access or why it might be failing? sql-server sql-server-2005 login share|improve this question asked Dec 19 '13 at 16:05 Mark Freeman 66911234 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote State 16 means that the default database was inaccessible. This could be because the database has been removed, renamed, or is offline (it may be set to AutoClose). This state does not indicate a reason in the error log. Resolve by fixing the missing database, or changing the login's default database using ALTER LOGIN, e.g. ALTER LOGIN [your_login] WITH DEFAULT_DATABASE = [valid_database]; This state may also be reported if the user's default database is online, but the database they explicitly requested in the connection string is not available for the reasons stated above. Basically, either your login is explicitly asking for an invalid database, or it is implicitly doing so because its default databas

Troubleshooting Error 18456 I think we've all dealt with error 18456, whether error 18456 state 38 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 http://stackoverflow.com/questions/20686293/sql-server-2005-getting-error-18456-severity-14-state-16-in-log 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 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 http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx 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 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).

The XYZ group has around 10 users in there who are successfully able to access the SQL Server database. I recently added a new user to this group (at AD level), but this person is not able to access SQL Server (through Mgmt Studio) and he's getting the error below Login failed for user. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. Error: 18456, Severity: 14, State: 11. I have already verified AD permissions are setup properly, user has restarted his machine, he is not part of any group that has DENY access and the SQL Server XYZ group has been removed and readded to the SQL Server instance in Mgmt Studio and server has been restarted. Any ideas on how to proceed further?

Can you have the new user try from another computer and see if that's the issue? Wondering if it's an AD setup issue, since your other users are working. –Jason Whitish Mar 25 '13 at 22:23 sqlblogcasts.com/blogs/simons/archive/2011/02/01/… –Aaron Bertrand♦ Mar 25 '13 at 22:26 Has the user logged off and logged on since the group assignment?
