I'm trying to add the RRAS VPN roles into my server 2012 box. The error I am getting is:

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. One or several parent features are disabled so current feature can not be enabled. Error: 0xc004000d At line:1 char:1 + install-windowsfeature -name directaccess-vpn + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (@{Vhd=; Credent...Name=localhost}:PSObject) [Install-WindowsFeature], Exception
+ FullyQualifiedErrorId : DISMAPI_Error__Failed_To_Enable_Updates,Microsoft.Windows.ServerManager.Commands.AddWind owsFeatureCommand

This box is running as a domain controller. Does anybody have any insight on having server 2012 running a domain controller and VPN endpoint on the same box?

Thanks!
