But I want to define another user (administrator) to log in with SQL Server Management Studio, so I did the following: Logged in to the server in Management Studio as sa. Right clicked on the database name. Clicked on properties. Then under permission, I select the required username (administrator). And I grant him all the permission.

Can anyone http://stackoverflow.com/questions/23667670/unable-to-log-in-to-server-in-sql-server-2008-r2-management-studio advise what might be the problem? sql-server authentication sql-server-2008-r2 ssms share|improve this question edited Feb 15 at 1:57 J0e3gan 6,30993059 asked May 15 '14 at 1:11 John John 23731233 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted You need to add a server login: Connect to your SQL Server with SSMS as sa. Drill into the server's Security folder in SSMS's Object Explorer pane. Right-click on the server's Security > Logins folder that appears in Object Explorer. Click on New Login... in the context menu that appears. Provide details of the new login in the Login - New dialog that opens - particularly its General, Server Roles, and User Mappings pages (along the left). (See the screenshots of each page with sample input at the bottom of the answer.) You may need to add a database user depending on your needs, but a server login (like your sa login) is necessary to connect to the SQL Server instance using Windows or SQL Server authentication. Mapping the new login to a database user (in the Login - New dialog's User Mappings page) will create a new user in the mapped database if you specify a username that does not already exist; alternatively you can map the new login to an existing database user. Another SO question speaks to the differences between server logins and database users. Login - New (General page) SQL Se

This eventID sometimes provides also state 1 which actually isn’t that useful as error 18456 due to security reasons any error is converted to 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 error 18456 windows a number of situations where you cannot do anything about it! We are 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 Accou

The generic message “Login Failed for User (Microsoft SQL Server, Error: 18456)” means you entered invalid credentials when logging into SQL Server. Video is short but has additional tips and tricks so watch the video to get the FULL STORY! In the below screen shot, I am logging into Microsoft SQL Server Management Studio with a user that does not have administrative permissions to connect to the server. You need to figure out what user does have rights to SQL server. Usually this is the user that you logged in with when you installed SQL Server or the user that is the default administrator on the computer. To get a list of users on the machine (Assuming Windows Server 2012 or above) Step-By-Step Launch Server Manager – Start – Click Server Manager In the upper right corner, click Tools, then Computer Management Expand Local Users and Groups (Under Computer Management-System Tools) then click Users Notice under Description… There is a Built-in account for administering… This is very likely an account that has access to SQL server. Try logging onto windows with that account that is Built-in account for administering then we can grant rights to the user you want to use to login to SQL Server. Now that you are logged into Windows with an account that has access to connect to SQL Server, Let’s go in and grant rights to the user that you want to be able to use to access SQL Server.
