I am having a very difficult time installing Direct Access on my Windows Server 2012. I have the computer joined to the domain, I have decided to go the 2 NIC path and deploy in the DMZ with NAT. Every time I try to add the role, with all the dependencies, it looks like it works, then I reboot and the all the roles are gone. I am getting multiple errors that range from my SMS Client, to WMI, and services like IP helper that do not start. Anyone having any issues with DA on 2012?
