Hi,

In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties.

On the Security page, under Server authentication, select SQL Server and Windows authentication mode, and then click OK.

In the SQL Server Management Studio dialog box, click OK to acknowledge the requirement to restart SQL Server.

In Object Explorer, right-click your server, and then click Restart. If SQL Server Agent is running, it must also be restarted.
