How can we improve Configuration Manager?

Bootimage download with HTTP instead of TFTP

Downloading the boot image with TFTP is slow and download may fail within slow or unreliable networks.
Downloading with HTTP or iSCSI will increase the speed dramatically and the stability is improved also.
With iPXE this technology is implemented and works fine.
My idea is to implement the HTTP download with SCCM.
This would be a great enhancement to performance and stability in the OS deployment.

Hi. I’m setting the status back to Noted – this was mixed up with the item “Add support for TFTP Window Size” – that has been Started and is available in the 1603 tech preview build.

    I realise this is an old request but I'd like to add another voice to this. It would be an incredibly useful feature to have natively in SCCM.
    While the other comments are right that iPXE does this, it shouldn't really be neccessary to use third party software, and it requires extra steps when you update your boot image that could be eliminated natively.
    Any chance this might actually get done?

    Add support for PXE over HTTP, we have experimented with iPXE and the performance is incredible, boot wim download from 5 minutes to a few seconds.

    Any updates on this? With newer machines that don't have an ethernet jack (MS Surface series, Latitude 7370, plenty of others), PXE boot is painfully slow - ranging from 30 minutes to several HOURS (if it doesn't just fail outright). Would be great to have a cure for that, not to mention speeding up the 3-5 minute PXE boot times of other machines.

    PXE reliability and performance has been a considerable hurdle for almost every organization that has tried it. On most ConfigMgr engagement I've worked on, regardless of network hardware vendor or age, PXE unfortunately has been something that requires several meetings to get it to kinda sorta mostly work in most places. Anything we can do to get off the TFTP protocol from 1981 will go a long way to making this actually work well in enterprises without so much pain and suffering.

    If loading the boot image/windows PE with http instead of TFTP, then it could also be WAN accelerated. Thinking ahead, it could might even work together with the cloud so you could boot an installation from a DP in Azure.

    Think about it. Bare metal installations from the cloud.
