Let's fix this error

To fix this situation, you first need to find out which user has rights to the SQL server. To see the list of users on the machine, you must start the Server Manager. Next, in the upper right corner, click on the Tools button, then go to Computer Management, click on System Tools, and select Users.

If in the provided list your account does not have access to connect to SQL Server, you should fix it.

To do this, start SQL Server Management Studio Again, expand your ServerName. Then expand Security and open Logins. Next, right-click to login and select new login.

Enter the Windows username that you want to add as a SQL administrator. Then click Check Names, click Server Roles in the left pane, and check the System Administrator box. Save your changes, and then you can confirm that you have rights by double-clicking the username in the left Object Explorer.

Then it remains to log out of Windows, then log in again as the user to whom you just granted the rights. This should fix error 18456.
