SERVER – FIX Error 18456, Severity: 14, State: 58. Login failed for user February 13, 2016Pinal DaveSQL Tips and Tricks2 commentsOne of the most common and searched SQL Server failure is around “Logins”. Login failed for user error 18456 severity 14 state 58 login failed for user has always been tricky and interesting to troubleshoot. I don’t think there is sql server error 18456 severity 14 state 1 a silver bullet to easily troubleshoot the same. With every version of SQL Server, there are enhancements made error 18456 severity 14 state 38 nt authority system in error reporting, which try to make life on DBA’s easy. In previous version of SQL, whenever there is a login failed, it would print message in the SQL ERRORLOG along error 18456 severity 14 state 38 sql 2008 r2 with the state of login failed. It was difficult for a DBA to find the cause further and it all boiled down to doing a number of permutations and combinations of resolution over the internet.

lot of articles over the internet world with this topic… error 18456 severity 14 state 8 but password is correct But this article is from my perspective which has detailed troubleshooting steps… The main problem with sql server error 18456 severity 14 state 16 troubleshooting connectivity issues with SQL Server is because the error message returned to client is almost generic and incase of login failures, the state is always http://blog.sqlauthority.com/2016/02/13/sql-server-fix-error-18456-severity-14-state-58-login-failed-for-user/ 1 So let me give you step-by-step approach in troubleshooting connectivity issues with SQL Server. Here is a flow of how connection to SQL Server is made: 1. Protocol used for making connections to SQL Server Connecting is made using a protocol based on the "Client Protocols" order specified in your local https://blogs.msdn.microsoft.com/sqlsakthi/2011/02/06/troubleshoot-connectivitylogin-failures-18456-state-x-with-sql-server/ box. In the case of screenshot given above, the connection made to any SQL Server fromthis client machinewill use "Shared Memory" protocol first and if that connection fails, it will try to use "TCP/IP" protocol and if that fails, connection request will be made using "Named Pipes" protocol. This is because I have all three protocols "Enabled" and I have specified the order in this way. Shared Memory protocol can be used only for local server connections whereby SQL Server should be running in the same box where you are trying connect. This protocol will not help you to connect to a Clustered SQL Server instance because the IP address of SQL Server is different from your local node. You can also force to use specific protocol using syntax: TCP:SQLSRVRNAME\INSTANCE for forcing connections to use TCP/IP protocol NP:SQLSRVNAME\INSTANCE for forcing connections to use Named Pipe protocol instead you can also use \\.\pipe\instancename\sql\query LPC:SQLSRVNAME\INSTANCE for

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 error 18456 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 for the most part several of these conditions appear the same to the end error 18456 severity 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 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
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'. (Microsoft SQL Server, Error: 18456) 1 Login failed for user 'username'. (Microsoft SQL Server, Error: 18456) Fo
