is kept fairly nondescript to prevent information disclosure to unauthenticated clients. In particular, the ‘State' will always be shown to be ‘1' regardless of the nature of the problem. To determine the true reason for the failure, the administrator can look in the server's error log where a corresponding entry will be written. An example of an entry is: 2006-02-27 00:02:00.34 Logon Error: 18456, Severity: 14, State: 8.

The number itself deliberately doesn't tell you much, so crackers can't use it for clues on where their attempts are going wrong. –Tony Hopkinson Jan 4 '14 at 16:10 8 @David if you see a duplicate question in SO, then mark this as such. Just because the answer is easy to come by, doesn't mean it doesn't belong on SO.

See below example. This usually means that your connection request was successfully received by the server name you specified but the server is not able to grant you access for a number of reasons and throws error: 18456. This eventID sometimes provides also state 1 which actually isn’t that useful as due to security reasons any error is converted to sql server state 1 unless you can check logging on the server. Microsoft does not provide very useful message boxes so below are some explanations why you get the error. Want to easily improve your SQL Server Skills? Before you dive in If you are NOT a DBA (Server Administrator) then read this. We had a number of online private chats using our website chat feature and we have identified there are a number of situations where you cannot do anything about it! We are sql server error aware some of you might be very new to this so I will provide you with simple list of questions or steps to check if you are in the 'cannot do anything about it' group. Before you start "fixing" it please go through the list below: Are you the person managing the server or the person who installed sql server (e.g. personal pc/laptop)? If no or you don't know, then there is a high chance you don't have permissions to fix it. What does it mean? It means you can only do what you are in control of (typing username, password) or trying steps that don't involve changing server configuration. If nothing works contact your server administrator (DBA). Are you connecting from an app (Visual Studio etc.) and not SSMS? If yes then try to connect from SSMS if it works then problem might be in the app. If no then is there any user account that works? Yes? Then username may not exist or might be mispelled. Password might be incorrect. Account may be disabled. No? Try next point. Using SQL Sever Management Studio (SSMS), Are you able to connect using Windows Authentication option (Not SQL Authentication, so without username and password)? If yes then check ifSQL Authentiction is enabled. If yes then check if you can create a new SQL Account and test it out. If it doesn't work than maybe service wasn't restarted (see previous link). If it does work then problem is with the acc

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. S
