Eu tenho um servidor FTP em uma máquina Windows Server 2012 e estou tentando obtersetup.exe a partir dele.

Log do CMD.EXE:

C:\>ftp 1.2.3.4

Por que funciona com o FileZilla, mas não com o FTP do Windows na linha de comando?

Mais do que isso, eu gostaria que um comando que fosse executado uma vez baixasse esse arquivo desse FTP sem pedir a senha.

Alguma ideia?

Obrigado.
