Hi,
I'm using WDS 2012 separated with DHCP Server. Everything running normal with PXE boot, but failed for EFI boot.
After a deep dive with wireshark, the root cause with EFI mode is the client is asking to WDS Server via DHCP protocol (DHCP Request) and the relay address is listed within the DHCP messages. In this mode, the WDS send DHCP Ack for that Request to Relay Agent.
And comparing to PXE mode, the client is asking to WDS Server via DHCP protocol and the relay address is NOT listed within the DHCP messages, so WDS send HC Ack for that Request directly to client.
Both PXE and EFI mode are tested using the same VLAN, same subnet, same DHCP Relay device, and same DHCP server.
Why is this happen? Am i missing something?
