Problem: When you try to use Windows Deployment Services to PXE boot a bare-metal target system, you get the error message DHCP did not reply to a request on port 4011" in other words the WDS server products no IP address for the PXE boot request.
Possible Solution #1: You've neglected to select the two DHCP integration options for DHCP in the WDS console, namely "Do not listen on DHCP ports" and "Configure DHCP options to indicate this is also a PXE server. " If you don’t select these options and the WDS service starts before the DHCP service, DHCP won’t work since both services attempt to bind to the same port.
Possible Solution #2: Your PXE bind policy is incorrect. To verify this, run the wdsutil /get-server /show:config command. If the output from this command includes:
Interface Bind Policy:
Policy: Only Registered
then this configuration causes WDS to not listen for PXE requests on any interfaces on the system.
