Here’s a neat thing to remember if you’re using MSSQL:

To change the “sa” password, login to your computer using an administrator account. Open your SQL Server and log in using Windows Authentication. Open a new query window and type in the following command:

SP_PASSWORD @NEW = 'new_password', @loginame = 'sa'

After that go to section Security –> Logins –> double click “sa” or choose properties. Go to “Status” and check to see if “Login:” is enabled. If not, enable it.
