Supported or not supported (by Microsoft) doesn’t really matter here though because Microsoft products have nothing to do with most of the PXE process – it’s almost entirely in the hands of the NIC to do the right thing. If something truly breaks down, it’s either the NIC’s fault or the network’s. The DHCP server can play a small role here, but ultimately, that role is truly insignificant as it’s still up to the NIC to determine what to do and then to do it. If the NIC does the wrong thing, there is no way to really troubleshoot it either and your only real recourse is to call the NIC vendor. There are NICs out there that some of us have encountered that simply refuse to do the right thing – these are pretty rare now days, but they do exist. With iphelpers, you simply have to watch the traffic if something weird is going on because it’s not up to the NIC anymore.
Experience has shown that iphelpers simply work better and as pointed out, with UEFI and architecture restrictions, DHCP cannot get the job done because it can only handle a single architecture.

I have personally experienced multiple instances at customer sites, just over the past year, where DHCP options have simply not worked as expected, and caused erroneous error messages during PXE boot. As soon as we implement IP helpers, everything “just works.” I am interested in gathering feedback from people on this mailing list to confirm or deny my current understanding on this topic. Do you use DHCP options or IP helper to point clients to the WDS/PXE service? Have you had a negative experience using one or the other?
