Troubleshooting Error 18456 I think we've all dealt with error 18456, whether it be an application unable to sql server 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 included, but 18456 sql server 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 there is no SQL log

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 free_mind 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 –free_mind Oct 31 '13 at 18:39 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted You can't use a Windows login with the -U parameter. -U is for SQL logins. If you want to connect as the currently logged in Windows user use the -E parameter to indicate you want to use a trusted connection. sqlcmd -S myserver -d mydatabase -E If you want to connect as a different windows user then you can run your shell (cmd, powershell, etc) as that user and use the above command. share|improve this answer answered Oct 31 '13 at 18:30 squillman 33.3k868126 Doing this still gives me the same error in addition to a new error MSG 4060, Leve
