TFTP working now Thank you all!!
great support here!!
Windows DHCP server configured
Installed the new Fog
and for connecting tftp from windows 10 tot test the firewall of windows was blokking it so thats way it failed. my windows firewall is standard. so standard it blocks using tftp like: C:\Users\Rene>tftp -i 192.168.2.233 get undionly.kpxe
hope it is no problem for managing windows 10 computers bij remote with the fog client.
