Not allowed. SQL Server security logins only, in the SQL Server login mode. Use the Windows login mode (it does not allow any password, and must be the current windows user). Otherwise, create the NT user as a login for security & database rights in SQL Server. If you are trying to do a Windows login with a different user name, you have to impersonate or run the program as that user. SQL Server has no ability to use Windows logins other than the current user. share|improve this answer answered Jun 3 '10 at 15:48 Jack Knows Jack 1863 add a comment| up vote 1 down vote This problem is down to you passing NT / Windows ac

also on Login failed for user with state 58. Let error 18456 severity 14 state 11 us see how to FIX Error 18456.After reading that blog, one of the blog reader contacted me
Error 18456 Severity 14 State 58
and told that she is getting state 6. I thought this error are very common and is important to demystify some of the reasons for the same. http://stackoverflow.com/questions/2964097/error-18456-state-6-attempting-to-use-an-nt-account-name-with-sql-server-authe I have asked completed error message to assist him. Here is the message she shared:Error: 18456, Severity: 14, State: 6.Login failed for user ‘sqlserver2016\sysadmin'. Reason: Attempting to use an NT account name with SQL Server Authentication. [CLIENT:
= 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. This message simply denotes that the http://sql-articles.com/articles/troubleshooting/troubleshooting-login-failed-error-18456/ client call was able to reach the SQL server and then an ACCESS was denied http://logicalread.solarwinds.com/errors-sql-server-login-failures-pd01/ to the particular login for a reason. To figure out the exact 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 for capturing login failures: By default, SQL server is configured to capture only error 18456 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 windows event viewer but how do I access them? Windows event viewer: GO to start –> Run –> Eventvwr error 18456 severity –> 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. SQL server 2005: C:\MSSQL\MSSQL.1\MSSQL\LOG\Errorlog SQL server 2008: C:\MSSQL\MSSQL10.instanceID\MSSQL\Log\Errorlog InstanceID - MSSQLSERVER for default instance and for named instance it’s the name of the instance STATES of 18456 State 1: This is a very generic error message that is sent to the client tools to deliberately hide
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) For security reasons (and to a hacker’s disadvantage), SQL Server avoids revealing the exact cause of error message. The way to tro
