Resumo

Os sites e aplicativos Web dependem da disponibilidade dos pools de aplicativos do IIS (Serviços de Informações da Internet). Os pools de aplicativos do IIS, por sua vez, dependem do WAS (Serviço de Ativação de Processos do Windows). Se o WAS não estiver em execução ou ocorrerem erros durante a inicialização ou o desligamento de um pool de aplicativos, os sites e aplicativos Web podem não estar disponíveis.
