O problema que enfrento é o cloud-init-base service. Se esse serviço for iniciado automaticamente, ele interferirá no processo sysprep quando a máquina for reiniciada ou inicializada em uma máquina diferente. Então, para concluir o sysprep, desativei este serviço na imagem original.
Agora, o problema é que, uma vez que o sysprep esteja completo e a máquina esteja ativa, cloud-init-base service ainda está desabilitado.
O mesmo arquivo funciona no Windows Server 2012 R2. No entanto, a mesma construção XML não está funcionando no Windows Server 2008 R2. Qual é a maneira de executar o comando no estágio oobe ou ativar o serviço quando o sysprep estiver completo?
Você precisa adicionar uma etapa automatizada após a reinicialização da máquina para ativar o serviço. Outra etapa na sua sequência de tarefas no SCCM, ou uma chamada de registro 'executar uma vez' executando um script para finalizar a compilação. De qualquer forma, alguns comandos do powershell ( Set-Service e Start-Service ) na sequência de tarefas (se você estiver usando o SCCM) ou em um script chamado de 'executar uma vez' devem resolver o problema.
