Can you please answer me straight to these below points, would be a great help
authentication issues could be a lot of reasons more commonly when contact with a domain controller is not possible.
logon issue would be more likely because of a policy related to computer being used.
A bit vague. What problem are you trying to solve?
I am trying to know the exact difference, when do i face authentication fail and logon fail over any server? what is the difference?
A falha de autenticação refere-se ao acesso a serviços, como diretórios compartilhadas ou aplicações web. Falha de logon ocorre quando se está tentando efetuar logon no sistema operacional.
