I have spent the last six hours reading lots of posts about this, but nothing seems to work.
I have two servers - PXE (WDS role on Windows Server) 192.168.20.89/24 and DHCP (Windows Server) 192.168.20.201/24
I have physical servers I am trying to deploy on network 192.168.10.0/24. I have set up the DHCP forwarders in my switches. (Cisco switches - ip dhcp relay address 192.168.20.201)
Pure DHCP requests seem to work fine. For example, I manually install Windows Server onto a system and I see the system get DHCP addresses. So it appears the DHCP forwarding is working correctly. But if I try to LAN boot the exact same server, it never gets an address. I sit on my DHCP server while the system is trying to boot and constantly refresh address leases. No leases are given out. PXE eventually times out and the system boots to the installed operating system. As soon as the operating system comes up, I see the leases on my DHCP server.
I have tried setting scope option 66 to the IP of my PXE (WDS) server. No difference. I have tried setting scope option 67 to root\x86\wdsnbp.com or root\x64\wdsnbp.com. No difference. Various combinations of 66/67 settings. No difference.
Everything works fine if the machine is on the same subnet as the DHCP and PXE servers.
Any ideas? Please don't point me to posts that say to set option 66 to the IP of the PXE server or option 67 to a program, unless there is something else I should put in there.
