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.

Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: ] Log Name: Application Source: MSSQLSERVER Event ID: 18456 Level: Information User: AVATOPIA\ian OpCode: Task Category: Logon i can login to the computer itself using Windows authentication. i can log sql server 2008 into SQL Server using the local Windows Administrator account. We can connect to 8 other SQL Servers on the domain using Windows Authentication. Just this one, whitch is the only one that is 2008 R2 is failing. So i assume it's a bug with *2008 R2. Note: i cannot logon locally, or remotely, using Windows authentication. i can login locally and remotely using SQL Server Authentication. Update Note: It's not limited to SQL Server Management Studio, standalone applications that connect using Windows authentication: fail: Note: It's not a client problem, as we can connect fine to other (non-SQL Server 2008 R2 machines): i'm sure there's a technote or knowledge base article describing why SQL Server 2008 R2 is broken by default, but i can't find it. Update 2 Matt figure out the change that Microsoft made so that SQL Server 2008 R2 is broken by default: Administrators are no longer administrators All that remains is to figure out how to make Administrators administrators. One of these days i'm going to start a list of changes around Microsoft's "broken by default" initiative. Steps to reproduce the problem How do i add a group to the sysadmin fixed server role? Here's the steps i try, that don't work: Click Add: Click Object Types: Ensure that you have no ability to add groups: and click OK. Under Enter the object names to select, enter Ad

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. Step-By-Step Launch SQL Server Management Studio again and you should be able to Connect Expand your ServerName, then Expand Security, then Logins. Click Logins Right-Click Logins Select New Login… Click the Search Button Type in the Windows User Name you would like to add as an SQL Administrator then click Check Names (or you can click advanced and select from a list) Click Server Roles in the left pane; then turn on the sysadmi
