При подключении
A connection could not be established to ' ... ' - Login failed for user '...'

Помогите плиз, что случилось, что делать ????

И при подключении локально и удаленно. Работал сервер нормально, ничего с ним не делали особенного и тут login failed.

Вот errorlog файл который создается при запуске sql севера. (может по его содержанию можно что-то узнать)
