Troubleshooting Error 18456 I think we've all dealt
Sql Error 18456 State 11
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 intentionally vague (the error message is similar for most errors, and error 18456 state 1 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 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 fo
> Security Problem Every once in a while you may run into an issue where a user cannot login to SQL Server, because the logins default database may not be available. This could be error 18456 state 5 for several reason such as that database was dropped, the database may be corrupt,

the database is offline, the user no longer has access to the database or even because the database was renamed. When
Sql Error 18456 State 28000
this happens the user will see an error message like the following on SQL Server 2005 and get a 4064 error. Or this error message for SQL Server 2008 and get a 18456 error. Or if http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx you are using a command line tool, you may see a text error like this: "Error: 18456, Severity: 14, State: 40. Login failed for user 'sqldbpool'. Reason: Failed to open the database specified in the login properties. [CLIENT: 10.10.10.10]". Solution This issue may not come up that often, but if it does here is a simple fix. The user can connect to another database, such as the master and then the default https://www.mssqltips.com/sqlservertip/2131/sql-server-login-issue-with-default-database/ database can be changed. Using SQL Server Management Studio Step 1: Open SSMS and click on "File" and then "Connect Object Explorer..." Step 2: Enter the server name, select the authentication mode, in this case I am using SQL Server Authentication where I also need to enter a login and password. Then click on the "Options >>" button Step 3: On the "Connection Properties" tab, type a different database name into the "Connect to database" drop down. You should be able to just connect to the master database, since all users have access to that database by default or you enter another database that you know the user has access to. Here is what this looks like for both SQL Server 2005 and SQL Server 2008. Step 4: At this point you can work with SQL Server as normal. If you want to change the default database you can open a query window and execute the below query to change the default database for the login Note: sp_defaultdb will be removed from the future version of SQL Server so you will need to use the ALTER command. Be careful with the database you select. You can pick any database you want as the default database, but if the user does not have acces
= 18456 Output: Login failed for user ‘%.*ls'.%.*ls%.*ls This is one of the infamous error message (and number) that most of the DBAs and developers have come across while working on SQL server. http://sql-articles.com/articles/troubleshooting/troubleshooting-login-failed-error-18456/ This message simply denotes that the client call was able to reach the SQL server and then an ACCESS was denied to the particular login for a reason. To figure out the exact http://dba.stackexchange.com/questions/29613/login-failed-for-user-error-18456-severity-14-state-38 reason, this error number 18456 with its STATE number is logged into the SQL server error log file, if SQL server was allowed or configured to capture the failed logins. Configuring SQL server error 18456 for capturing login failures: By default, SQL server is configured to capture only failed logins but it can be changed to any of the options as mentioned in this books online link http://technet.microsoft.com/en-us/library/ms188470.aspx Below figure shows these options to have login failed messages written into error log Accessing Error log: Now that, we know SQL server logs all login failed messages into its error log and error 18456 state windows event viewer but how do I access them? Windows event viewer: GO to start –> Run –> Eventvwr –> open up the application logs, and now we could see the login failed error message with computer name, instance name, date and time and finally the reason for the login failed SQL Error log: SQL server error log can be viewed from multiple places If we have gained access or can gain access to SQL server with different logon credentials then always use sp_readerrorlog, xp_readerrorlog or use the GUI option of opening up Management node –> SQL server Logs –> View –> SQL server log. Same sample shown above looks like In a case where we cannot gain access to SQL server, then we may use the actual error log path and open the txt file physically from the file system. Use SQL server configuration manager to find the error log path and from there you could open the file. Get the value next to –e parameter and that gives the actual error log file location Typically the error log files are available in install directory for SQL server.
