I\'m creating new login in SQL Server 2008 with following sql script:
CREATE LOGIN [xyz] WITH PASSWORD=\'xyz\',
DEFAULT_DATABASE=[master], DEFAULT_LA
Here is how I done it, maybe it works for you too.
login Microsoft SQL Server 2012 with windows authentication.
right-click onto the server name in Object Explorer and click Properties
In the new tab click Security
select SQL Server and Windows Authentication
Ok
Close the SQL server management studio.
start+run
write services.msc
search for SQL there and restart all services.
that works for me.
