    Hi
    We have a WDS server on windows 2008R2 sitting on a network1. We also have DHCP with options 66 and 67 and a few PCs on the same network, and deploying windows 10 via the network to PCs on the same network works fine.
    We also have network2 which is routed to network1. On network2 we have DHCP with same options 66 and 67 and few PCs. I have also set IP-Helper on a router pointing to WDS server on network1.
    But if I try to load windows via the network on any PC in network2 from WDS server, I am getting error “PXE-E79:NBP is too big to fit in free base memory” on a PC.
    Most of the articles regarding this error points to setting IP_Helper which I have done.
    Also some people mentioned there should be small file set as boot image which loads the main image but I just cannot find how to do it.
    Thanks

    IP-helper addresses point to your DNS & DHCP servers, as well as the Deployment server. Try adding those addresses to the same router interface. If your WDS setup works when a PC is on the same subnet as the servers, then that config (boot files, etc.) should not need changing. But IP-Helper info has to include any IPs that deal with DNS as well as DHCP and AD, in addition to the WDS side.

    We have a small testing environment where using windows 2008 with Routing and Remote access as a router. Correct me if I am wrong, but IP Helper is the same as DHCP relay which I have set pointing to WDS server. Not sure why would I add DNS server to IP Helper as we are only using ip addresses. Also not sure about adding DHCP address to IP Helper as we have DHCP server on the same subnet as PCs.

    Thanks

    Couple of options here which resolved the problem, one was the IP-Helper address and the other was to set the system to boot from UEFI.
