Is your client in the same subnet as the PXE-Server?
If not, it could be a problem with your router-config:
Some routers only allow DHCP answers from servers wich are defined as IP-helper for this subnet.
In other words: Your client would get the answer from your DHCP-server and then asking the PXE-server, but the answer of the PXE-server would be dropped by the router.
