• Wds Windows Failed To Start

I am to an issue when iPXE load undionly.kpxe, it will show 'Failed to restart TFTP',1. Bellow is my detail environment:-1) have about 1000 NoteBook in my network2) have three DHCP&iPXE server3) These NB all with USB LAN card2. Issue like bellow info(I don't know how to upload picture as attachment, so.)-Realtek USB Ethernet controller (xHCI) v2.10AD(11/24/16)CLIENT MAC ADDR:00 E0 4C 62 C6 26 GUID:44454C4C-3800-1056-8053-C4C04CLIENT IP:100.110.153.105 MASK:255.255.0.0 DHCP IP:100.110.3.4Downloaded WDSNBP from 100.110.3.4 WIN-RCLVTQ9LUFKPress any key to cancel network boot serviceArchitecture:x64Contacting Server: 100.110.3.4.Failed to restart TFTP.TFTP download failed.PXE-M0F:Exiting PXE ROM.No Boot Device Found. Press any key to reboot the machine3.

Condition for issue happend-1) there lots of NB in network, if there have 100 NB, it can boot normal2) more than DHCP&iPXE servers, if only have one DHCP&iPXE, it can boot normal3) only happend with USB Ethernet, if NB with onborad Ethernet will boot normal4) only happend with iPXE boot, WDS boot normalI use Wireshark get the Packets, I found NB can get bootx86wdsnbp.com by TFTP, but after NB show 'Contacting Server: 100.110.3.4.' , NB show error like above info, and during NB show 'Contacting Server: 100.110.3.4.'

Prosper software crack. , there have only two type packets, one is 'DHCP request', the other is 'DHCP ACK', who can hep me with this issue??Many thanks,RichardChen. NiKiZe, thanks for your reply,1.we use the server2012 for DHCP&iPXE, so we haven't found the logs for TFTP service2.I checked wireshark packets of onboard LAN and USB LAN, no exception information was found.3.we checked the packets of wireshark for normal boot iPXE NB, we found after NB show 'Contacting server 100.110.3.4.' , it will start to get bootundionly.kpxe by TFTP, there have only two types packets(DHCP request,ACK), and only need about 1 second it will start to get undiony.kpxe. But for fail boot iPXE NB, it always show dot with 'Contacting server 100.110.3.4', and after about one minutes, it will show TFTP error, i checked the packets of wireshark during show 'Contacting server 100.110.3.4.' , there only have DHCP request and ACK, no any others packets, also have no packets for starting TFTP bootundionly.kpxe.

I am very puzzled that why it can get bootx86wdsnbp.com by TFTP at first, and it show TFTP error after 'Contacting server 100.110.3.4.' , what is it doing during 'Contacting server 100.110.3.4.' (2017-07-18 09:30)richardchen Wrote: 3.

As already mentioned this has nothing to do with iPXE.(2017-07-18 09:30)richardchen Wrote: 2) more than DHCP&iPXE servers, if only have one DHCP&iPXE, it can boot normalWhat do you mean by iPXE server? TFTP server hosting the iPXE binary or HTTP server hosting the iPXE script? Possibly you have your DHCP servers configured differently. In this case you'd see client boot properly sometimes but fail when clients get an answer from a DHCP server giving false information.(2017-07-18 09:30)richardchen Wrote. We checked the packets of wireshark for normal boot iPXE NB.How and where did you capture the packets?

Next to the client (using a hub or mirror port on the switch) or on the server - which server exactly? As you seem to have several servers for DHCP/TFTP you better capture on the client side to make sure you don't miss any packets. SebastianRoth, thanks for your reply,I'm sorry to say nothing about the quantity of DHCP&IPXE, we found if there only have one DHCP server, it can boot normal.

We use this solution for WDS and iPXE long time.Current this issue only happend with USB LAN card, production with lots of units and more than one DHCP, If any of these three conditions is missing, this issue also can not been duplicated, these units have no onboard LAN, so we must use USB LAN card. We also cannot split the network, because have no lots of procution server. So current used one DHCP&iPXE server for short time solution. However, this solution poses a risk of stopping production.The point of this issue is why it always send DHCP request when DHCP reply ACK? And why it always repeat this stepping and not begin to go next stepping for TFTP undionly.kpxe?
