Error 18456 State 16
SQL Saturday events worldwide. 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 sql error 18456 state 11 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 for the most part several of these conditions appear the same to the end user. In order to figure error 18456 state 1 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 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

Login failed for userIn about an hour, I received a mail again stating the above were not solving his problem. He sent me a bigger screenshot as shown below:Though this was a good http://blog.sqlauthority.com/2016/09/08/sql-server-fix-error-18456-severity-14-state-5-login-failed-user/ starting point, this was not good enough information for me based on what SSMS was sending as output.I reviewed the above blogs just to realize I had forgotten to give a bigger detail. A lot of these login failures are also logged in ErrorLog. I realized and asked the Developer to check in their error log. And incidentally, they figured out the actual root cause. Since he didn’t get back to me for 3 hours – it was my turn to ask what went wrong because I was curious to understand the actual reason. I got a screen shot as shown below and it explained quite a bit.If you are not sure where to get the ErrorLog, check the post: SQL SERVER – Where is ERRORLOG? Various Ways to Find ERRORLOG Location.On further investigation, it was learnt that their application was changing the password for their users in their application code, but since it was load balanced, it was getting into some mess. But I was glad how explicit and detailed information Error Logs give that helped this user.Have you seen and used such information in your environments for such failures? What were your troubleshooting tips?

I then installed CAS for SCCM on another server. The prerequisites required me to change the collation on the existing server. I did this and ran a rebuild database command at the same time. The error 18456 state SCCM database for the site dropped, along with a reporting database and temp reporting database. I had to re-add some users to the instance and marry up with the reattached databases (the ones that had dropped). I am now getting a SQL Server error as follows: Error: 18456, Severity: 14, State: 5. 2013-11-20 16:28:44.73 Logon Login failed for user 'DOMAIN\MACHINENAME$'. Reason: Could not find a login matching the name provided. [CLIENT: ] SCCM user auto discovery isn't working as new users in AD are not being written into the database, probably due to this. I have recreated the local machine user and checked NT AUTHORITY\SYSTEM, NT AUTHORITY\NETWORK SERVICE, and DOMAIN\MACHINENAME$ users match between the databases and the server and the SIDs all match. To do this, I used: select * from sys.database_principals select * from sys.server_principals All connections are local and using windows authentication. The owner of the SCCM database is 'sa' and the SID matches. TCP/IP and named pipes are enabled, the ports for connection are static. The 3 users above are set as sysadmin on the server.

Server Login Failures By Pinal DaveWhen asked about common errors encountered in a SQL Server environment, you might expect to hear about high CPU issues, but in reality, these are rare and few. In fact, many DBAs report connectivity issues with SQL Server as among the most frequently encountered errors. These errors can further be classified into two sub-categories: Login request not reaching SQL Server. Login request reaching SQL Server and then failing. Let's look at each of these scenarios in this article. Scenario 1: Login request not reaching SQL Server A typical error received by a client might be: Transact-SQL A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections 1 A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections There can be multiple reasons for this error, including these, based on work I've done with clients and queries I've responded to in user forums: Using the incorrect instance name. The SQL Service is not running. Port not open. (Note that telnet is the best test possible to detect this). The SQL Browser Service not running. (This is needed to get port of named instances. IP, PortNumber - can be specified to identify this issue.) Incorrect DNS entry and request going to different machine. (Note that ping is the best test to find name and IP address mapping). Scenario 2: Login request reaching SQL Server and then failing This second scenario results from authentication or security related errors. The error message received by the client would as shown below: Transact-SQL Login failed for user 'username'.
