I am trying to drop and recreate sa account to reset the password.
IF EXISTS (SELECT * FROM sys.server_principals WHERE name = N'sa') DROP LOGIN [sa] GO
I am getting an error
Cannot use the special principal 'sa'.
also when I try to reset sa password in SSMS, I am getting an error
Cannot alter the login 'sa' because it does not exist or you don't have permission. Error: 15151
