Cause

Há muitas causas possíveis para esses erros. Nesse caso, a senha do domínio foi alterada após a criação da sessão de migração.

Resolution

Uma das seguintes etapas pode ajudar a resolver esse tipo de problema:
1) Atualize as credenciais de administrador nas propriedades da sessão de migração no Unisphere para que correspondam à senha atual.
2) Crie um usuário administrador local no servidor CIFS do VNX usando o Microsoft Computer Management (MMC). Configure as credenciais de administrador nas propriedades da sessão de migração no Unisphere para corresponder a essa conta de usuário recém-criada.
3) Se a senha tiver caracteres especiais, tente alterá-la para uma senha alfanumérica.
