Pessoal, neste artigo mostrarei uma forma fácil de alterar as senhas de administrador local em máquinas de uma rede, diminuindo o esforço para o técnico ter que ir de máquina em máquina para realizar a tarefa. Para isso, vamos utilizar uma ferramenta do pacote Sysinternals.
Para iniciar, baixe a ferramenta Sysinternals:
http://technet.microsoft.com/en-us/bb897543.aspx&nbsp;
Após baixar, descompacte o arquivo em C:Acesse o prompt de comando (DOS) como administrador, conforme imagem abaixo:



&nbsp; 
e naveque até C:\PSTools
Através do comando abaixo, podemos alterar a senha de um computador de nossa Rede:.
pspasswd \\nome_do_computador administrador &nbsp;novasenha  Podemos também utilizar um script com o nome de todas as contas das máquinas no AD para alterar o mesmo. O comando abaixo chamará o arquivo em txt que contém o nome dos computadores:
pspasswd \\@file.txt administrador senha  Para usar credencial administrativa na alteração utilize o comando abaixo:
pspasswd \\@file.txt -u useradm -p senha administrador senha
