First task you might check is to see whether that user has relevant privileges on that SQL Server instance and relevant database too, thats good. Obviously if the necessary prvileges are not been set then you need to fix that issue by granting relevant privileges for that user login. Althought if that user has relevant grants on database & server if the Server encounters any credential issues for that login then it will prevent

Troubleshooting Error 18456 I think we've all dealt http://serverfault.com/questions/549985/sql-server-2008-r2-error-18456-state-1-login-failed-for-domain-username 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 sql server 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 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 18456 sql server 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 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 contain

In the management studio the account I'm using has the dbo_owner privileges on the instance and the database. Also I connect to the instance using those same credentials. In my event log I also have this error: Login failed for 'domain\username'. Reason: Failed to open the explicitly specified database [CLIENT MY_IPADDRESS] I'm no SQL expert and could use some help troubleshooting this if possible. sql-server sql-server-2008 authentication share|improve this question asked Oct 31 '13 at 18:19 hax0r_n_code 2471415 There should be an error in the event log as well that looks like Error: 18456, Severity: #, State: #. What's that one look like? You will always receive a state 1 error from the command line. The state error indicates the source of the problem. –cole Oct 31 '13 at 18:34 @Cole there is no state field in the event log. The only other info is level 4 and task 0 –hax0r_n_code Oct 31 '13 at 18:39 add a comment| 1 Answer 1 active oldest vote
