Early indications show me that State 16 is an old, generic message, meaning the db couldn't be opened. Either the user lacks permissions or the server is inaccessible: sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/… –Danny Beckett Mar 20 '13 at 5:28 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote I've seen this in the past. After researching around we found that this was due to the user not having permission to login to the database that has been setup as their default. It was a newly setup DB user for use by SSIS imports. We used ALTER LOGIN to resolve the issue. ALTER LOGIN [username] WITH DEFAULT_DATABASE = [database name] Note: This was using SQL Server 2008 but it should be the same for 2005. share|improve this answer answered Mar 20 '13 at 7:02 Gibron Kury 1,1501823 Note I f

Every attempt to create the database is giving a 'login failed' style error. For testing purposes I am using the same account on the SharePoint web application and timer service, Microsoft SSO Service, and in the 'Manage Server Settings for Single Sign-On' page in SharePoint. The two SQL Server errors being logged are: Login failed for user 'blah' Error: 18456, Severity: 14, State: 16. The Windows Server event log error show the same 'Login failed' message with the word 'master' in the data section. I have tried: Giving the user sysadmin permission on SQL Server Changing the default database to one where the user has db_owner permission as well as setting it to 'master' Making the user local administrator on the SQL Server The comments in this article on the SQL Protocols blog state that: State=16 means that the incoming user does not have permissions to log into the target database... This can also happen if for example the default database for user FOO is not online (for example the database is marked suspect). I think I've covered the permissions and SharePoint is using the databases so they shouldn't be marked suspect.
