Hi!
I've confugured NAP DHCP Enforcement and apply user nap settings throw GPO (Enable enforcement and start nap and wscsvc).
All Windows XP PCs works fine after applying GP. All agents initialized well.
But all Vista and Seven couldnt initialize WSHA(this solution is useless: technet.microsoft.com/en-us/library/cc735495(WS.10).aspx)
Group Policy are the same everywhere.
Maybe someone came across this?
