    Step 1. remote Connection To A Computer

    Troubleshooting and finding solutions require you to surf the server or quickly connect to MSSQL with Windows authentication using Microsoft SQL Server Management Studio. The most common and easiest way is to connect directly to the server via Remote Desktop Connection. If you need more information about Remote Desktop Connection, this Knowledgebase will help you connect:

    Step 2 Or 3: Start Microsoft SQL Server Management

    After connecting to the server, you want to launch Microsoft SQL Server Management Studio (SSMS). Generally, SSMS is the most suitable tool for configuring, running and managing MSSQL.

    Could not find a login matching the name provided 18456 State 5?

    Cause: An absolute connection could not be found that matched the given name. The connection (which uses SQL and Windows Authentication) does not exist. For Windows Authentication, this probably means that the login has not received explicit logins in SQL Server, i.e. it is not someone from the appropriate domain group.

    When you start SSMS, you will be prompted to connect to the server. Without paying, most MSSQL servers have Windows Authentication enabled i.e. H. You need to be logged in with a Windows Administrator or the specified entry as a SQL Administrator since your MSSQL has been installed and configured. Addition

    For Windows authentication, MSSQL supports SQL Server authentication. Depending on Not translating MSSQL and how it should be installed and configured, SQL Server Authentication may not be enabled by default.

    Step 3: Check The Server’s Authentication Mode

    If you have set the server authentication mode to allow SQL Server and Windows authentication, you can connect to MS-SQL using an SQL username and password or a Windows username and password. After making this change, this audience will need to restart the SQL Server service.

    Step 4: Restart The SQL Service At Targetom

    In SSMS, right-click the server name at the top of the Object Explorer window and select Restart to apply rings for the new authentication mode.

    In the example above, the Windows authentication mode was the only mode created and error 18456 occurred because the sa user is a SQL user and SQL Server authentication was not previously allowed.< /p >

    Step 5: Check The Permissions Of The SQL User

    When checking the permissions of visitors to the SQL website, we need to answer all of the following questions:

    Could not connect to SQL Server using Windows Authentication?

    Go to Control Panel -> Administrative Tools -> Services.Open the SQL Server Browser service and enable it (manually or automatically, depending on your needs).Start it.

    In SSMS Object Explorer, expand Security, Logins. Find the user who failed to log in. A c symbol on a user indicates that that skill user has disconnected the connection.

    To log in to a user, right-click, log in to a specific user, and select properties, then only the status page. Enable login for everyone and users click OK.

    After updating our own user IDs in the listwe definitely need to make sure that the user no longer has a red cross. This would like to give the user the ability to load firewood. For example, the SQL friendly “sa” failed to connect due to lack of login permission.

    To continue troubleshooting, right-click any user and select Properties. Then just click on the “General” page. Here you can enter a new password and then enter a confirmation password. Click OK to reset your password. We are setting a brand new password for the worker so that we know exactly my password when we try to login.

    Step 6: Assign A User To The Database

    Our last step in user troubleshooting is to look at the user mapping to make sure the user has access to the correct index and set or verify part of it for the database. Right click on each and select “Properties”. Then just click on the user mapping page. Select a database from the list of databases. Select desired/neodesired membership in the database membership role. click OK.

    How do I fix SQL Server login failed?

    Click Windows and type SQL Server Management Studio.Now right click on SMSS and select “Run as administrator”.Then click “Yes” (when a UAC prompt is received) and click “Money” when SQL Server shows error 18456.If not, check if disabling User Account Control on the server solves the problem.

    In this user-friendly example, we have assigned the ProdX709 player to the Production X709.2019 database and have additionally assigned it the db_owner database role. In many cases, you only need an absolute user with db_datareader roles and only db_datawriter to be able to write to the appropriate database in addition to reading.
