I am getting the error when I enter into sql server as follows,
Login failed for user "sa". The user is not associated with a trusted SQL Server Connection.

Actually I forgot my password and I need change SQL Server password. Is there any possible to change the password?

Hi,

Two way to changing the 'SA' Password.

1)
USE [master]
GO
ALTER LOGIN [sa] WITH DEFAULT_DATABASE=[master],
DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=ON, CHECK_POLICY=ON
GO
USE [master]
GO
ALTER LOGIN [sa] WITH PASSWORD=N'lion' MUST_CHANGE
GO

2) From a command shell (start > run > cmd)
OSQL -S <YOUR_SERVERNAME_GOES_HERE> -E
Synatax
sp_password 'Old','New', Account

1> EXEC sp_password NULL, 'lion', 'sa'
2> GO
