In other words I have 6 users using the same sql server error 18456 severity 14 state 58 application with different logins, but the application itself is logging into SQL server with a single login. One of my users is having issues. When she logs into application the first time, she gets in fine, but if she tries to reopen it, it fails. If she reboots her computer, she can log in one time again.

I had to help a client out with an error that kept appearing in their event logs: Login failed for https://justaprogrammer.net/2012/12/09/a-misleading-sql-error-message-error-18456-severity-14-state-38/ user ‘domain\user'. Reason: Failed to open the explicitly specified database. [CLIENT: 192.168.0.25] http://logicalread.solarwinds.com/errors-sql-server-login-failures-pd01/ It took me a while to troubleshoot the error. The client's internal system administrator (who was quite sharp) only had to call me in in the first place because the error was a little misleading. See the first thing I did when I saw that was error 18456 audit login failures. In the trace, the database was listed as master. The user had full access to master. However, I later learned that the user was switching from master to a non-existent database, which was triggering this error. I figured this out thanks to Sadequl Hussain‘s article, SQL Server Error 18456: Finding the Missing Databases. Sadequl error 18456 severity explains in detail the how and the why. However, the take home is you need to trace for User Error Message to get the message that tells you what database you are connecting to. This took me about an hour to solve. Honestly, it was a bit humbling of an experience. It took me an hour to figure out something a full time senior DBA would probably be able to solve in 15 minutes. However, I'll probably be able to solve this error in 15 minutes myself go forward. Finally, the fact that it took me a while to find this one blog article that explained what the issue actually was proves how dependent I've become upon google.

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 troubleshoo
