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.

[CLIENT: XXX.XXX.XX.XXX](where XXX represents Ip address of client machine)After that the client machines are not getting connected to sql server. Actually I have 2 applications connected to the same sql server. One is working perfectly fine http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=110713 while the other is not able to connect. Both the applications are connected through sa.

Troubleshooting Error 18456 I think we've all dealt 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 returned to the client or application trying to connect is error 18456 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 just today solve a error 18456 severity 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). If you don't specify a database in your connection string,
