We are having a problem deploying Windows OS from WDS for new 4th Gen laptops with I218-LM.



Environment :



1. WDS installed on server 2012 (VLAN 1).

2. We have 5 buildings in the campus. Each building is a seperate VLAN.

3. DHCP server is on VLAN 1 (Building 1 - Datacenter).



Scenario :



1. We have more than 3000 clients, on which we are able to deploy OS through current setup.

2. We bought 100nos of new Acer TM645 and HP elitebook 840, which are both 4th Gen Intel i5 with Intel I238-LM Ethernet Port.

3. We tried PXE boot these two model but we get - "PXE-E52 proxyDHCP offers were received. No DHCP offers were received". It doesnt even acquire IP. But it recieves IP in OS mode and network works fine. Only PXE problem.

4. We tried to take the laptop and connect in the same VLAN as DHCP i.e. VLAN1. But still same error.

5. Then we setup a private network through a sepearte switch with another DCHP and WDS and booted. It booted and worked. We are able to deploy OS.

6. Note : We have put BIOS in legacy mode not UEFI.

We have now purchased new Dell 9020 which comes with l217-LM. Same issue with that pc.

Is this a problem with any VLAN configuration or related to STP in network switches with fast ports.


Has anyone faced this kind of problem. Any solutions?

It is likely a issue with either the DHCP server or the helpers in the switch. What I have seen microsoft like normal does things their own way compared to other pxe boot systems. It seems microsoft likes you to have the DHCP server and the WDS on the same device.

You need to ensure that DHCP options used for pxeboot are set correctly and sent to the user so they can find the WDS machine. The other option is to put in a second helper address so you can use a broadcast method to find the WDS.
