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
Sql Server Error 18456 Severity 14 State 1
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 error 18456 severity 14 state 38 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).

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? Thanks, Dave sql-server share|improve this question asked Dec 11 '12 at 13:12 Comanighttrain 922512 add a comment| 1 Answer 1 active oldest votes up vote 6 down vote accepted How does UAC work? 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 '1
