Is this a new install? It looks as though SambaPOS is trying to use the current user to login and that isn’t supported.

Your options are either reinstall SQL Server and enable mixed mode authentication and then set the sa or follow the instructions here to update your installed instance: Change Server Authentication Mode - SQL Server | Microsoft Learn

Hi its a new install ive tried reinstalling it several times and still cannot open Sambapos

You need to ensure mixed mode is selected.

See

and scroll down to “In this screen select Mixed Mode.”

then follow the rest of the steps
