Estou tentando instalar o Recurso Windows DSC-Service em uma máquina Windows 2012 R2 com o WMF 5.0 já instalado. A instalação falha com os seguintes erros:
Install-WindowsFeature DSC-Service :
Install-WindowsFeature : The request to add or remove features on the specified server failed. Installation of one or more roles, role services, or features failed. The source files could not be downloaded. Use the "source" option to specify the location of the files that are required to restore the feature.
dism.exe / online / Ativar-recurso / recursoName: DSC-Service

Eu também tentei instalar o .NET 3.5 (para ver se as fontes são baixadas) e isso funciona bem.
Existe algum lugar ou maneira de obter as fontes do DSC-Service para instalar o servidor pull no Windows 2012 R2 com o WMF 5.0?
O erro foi resolvido - a causa raiz foi uma imagem do Windows a partir da qual a máquina foi instalada, onde os recursos do Windows não são apenas "não instalados", mas também "removidos". Aparentemente, o Windows e o mecanismo de atualização não lidam bem com essa situação.
