When I tray to login to SQL Server, all users are disabled and fail with error 18470. Even Windows Authentication.
Login failed for user ‘NT ServiceSSISScaleOutMaster150’. Reason:
Could not find a login matching the name provided. [CLIENT: local machine]
Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.
