Win2008 DHCP server unable to service clients when Network Access Protection enabled.

I have been following the NAP_DHCP_StepByStep.doc guide on the microsoft website and the only difference I have in my environment is that NAP and DHCP are both installed on the Windows 2008 DC as opposed to a separate server. The problem I have is that the instant that I enable NAP (DHCP scope properties | Network Access Protection Tab | NAP Settings enable for this scope) DHCP no longer services requests. Does anyone have an idea where I'm going wrong here? It works fine when this option isn't selected and the client itself shouldn't even be affected at this point as it isn't in the test machine group.

Apologies for the late reply.
Turns out that I hadn't fully uninstalled the DHCP services from the original W2K3 server and this produced some kind of conflict with the 2008 DHCP. Everything working now, thanks.
