See below example. I did some research online and found out that this usually means that your connection request was successfully received by the server name you specified [so why didn't it work], but the server is not able to grant you access for a number of reasons and throws error: 18456. Video shows you the steps🙂 Below is a list of reasons and some brief explanation what to do: SQL Authentication not enabled: If you use SQL Login for the first time on SQL Server instance than very often error 18456 occurs because Windows Authentication (only) is set in Server properties (security section). To Access Server Properties, Open SQL Server Management Studio, go to Object Explorer pane (use view if you can't see it). Use the connect button to connect to database engine for your server. Once connected you will see it in object explorer. Right click server and click properties. Server Properties window will appear. See below screenshot that might be
Microsoft SQL Server login failed error 18456 can be encountered due to varied reasons. When this error occurs, the server name entered is correct, but because of some unanticipated reasons, the permission to login cannot be granted. This error can be confronted in spite of the SQL Server edition or its type (Enterprise or Express) in use. Introduction Most of the time, an error code comes up with a description that gives a hint about what has gone wrong. But unfortunately, in case of error code 18456 on screen, no cause of login failure is displayed. This is an intended development of the application in order to have protection against unauthorized users (probably, someone is trying to have entry to the server on the basis of guess information). However, the administrator can check out the event log in order to get details about occurrence of SQL Server error 18456. Cause of Microsoft SQL Server login failed error 18456: 1: At the time of Server login, if either the username or password is incorrect, the error will be generated. 2: When an SQL Server instance is logged in for the very first time, possibility is that the users encounter an error 18456. This generally happens when the “Windows Authentication” is enabled under the security section and SQL Server is unable to recognize the user. 3: Possibility is that the password for login is expired. This can also happen while disabling the username on server. Resolution: Before we get started with the troubleshooting steps, make sure that the login credentials (username and password) entered is correct. If Windows Vista or Windows 7 is used, then run SQL Server through Run as Admin option. This might give a solution. If Windows authentication is enabled and the error is received, then use the SQL SA credentials. Moreover, check out if the Windows Active Directory has SQL login information associated. In order to add a user to the S
