I just spent a good hour trying to figure out why my Windows 10 clients were not getting assigned an IP Address from my DHCP servers once I enabled NAP integration on the scope. The reason of course is obvious: NAP was deprecated in Windows Server 2012 R2.
The NAP client is not available on Windows 10 computers. You can’t even see the Network Access Policy node when you edit a GPO using Windows 10 RSAT:
So if you’re wanting to configure your Windows 10 computers with DHCP and you’re using NAP, you’ll need to disable it or create a special scope without NAP enabled with a DHCP Scope Policy for your Windows 10 clients. As this technology has been deprecated you’re probably better off removing NAP entirely. Pity I’m having to spend time studying it for my 70.411 exam.
