Hi,
maybe I found the problem. When switching on the Netduino Plus I get following DHCP request:
1) DISCOVER with YourIP 0.0.0.0
2) Reply from my DHCP server with OFFER and IP address 192.168.178.96
3) REQUEST with YourIP still 0.0.0.0 instead of the offered IP 192.168.178.96
4) Reply with ACK
When comparing i.e. with Thaoe-II I have a difference with the step 3, the YourIP and ServerIP is filled correct instead of using 0.0.0.0.
I have attached the capture of both requests.

I don't really know how to tell this but I will give it a try.
The step 3 when it sends out a request should be 0.0.0.0 for a device that have never got an ip adress before. It will send it as a broadcast so that all the dhcp servers on the network will know about it.
The reason why the Thaoe will send it it's ip adress I don't know but as far as i know the whole DORA process is with Boradcast (Except when there is only a renew, and not a release renew)
I would really like to see the captures with wireshark though.
Sorry for the bad english..
