SQL Server Security Question 0 Sign in to vote Hi All, I am getting the following error 18456 severity 14 state 38 error in the ERRORLOG File when I am trying to connect to SQL Server 2005 Enterprise Edition 64bit with SP2 from Reporting Services Configuration tool -

Database Setup. The SQL Server database and reporting services are on 2 different servers. Both are running 2003 SP2 64 bit. 2007-04-12 07:30:05.54 Logon Error: 18456, Severity: 14, State: 8. 2007-04-12 07:30:05.54 Logon Login failed for user 'sa'. [CLIENT: xx.xx.xx.xx] I know my password is valid as I can logged into SSMS using SA. error 18456 severity 14 state 38. sql server 2008 r2 I can create the 2 reportserver databases using the Reporting Services Configuration tool on the database server. The db server is in MIXED mode. What am I missing? Related articles I have followed are: Login failed for user 'x' http://msdn2.microsoft.com/en-us/library/ms366351.aspx Change Server Authentication Mode http://msdn2.microsoft.com/en-us/library/ms188670.aspx Any help to get passed this problem would greatly be appreciated. Thanks in advance for your time! Thursday, April 12, 2007 4:01 PM Reply | Quote Answers 0 Sign in to vote On both servers we have Windows 2003 Server 64bit with SP2 applied. I previously visited the second link listed above. All its explains that a State: 8 is a password mismatch. I know I'm entering the password correctly in the Reporting Services Configuration tool. However, I believe when it gets sent to the db server it is missing or encrypted someway that the db server can't decrypt.Thanks again. Thursday, April 12, 2007 6:46 PM Reply | Quote 0 Sign in t
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
Error 18456 Severity 14 State 1
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 error 18456 severity 14 state 16. login failed for user 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 https://social.msdn.microsoft.com/Forums/sqlserver/en-US/ed85f47c-0c00-4d49-b8dc-9913911b3756/logon-error-18456-severity-14-state-8-need-help?forum=sqlsecurity 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 http://logicalread.solarwinds.com/errors-sql-server-login-failures-pd01/ 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 troubleshoot these errors is to look into the SQL Server Errorlog. The location of the file can be found using SQL Server Configuration Manager. Under startup parameters, we need to look at -e which stands of path of Errorlog. Below are some error messages which w
= 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 https://scn.sap.com/thread/3506534 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 severity 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.
