DHCP Scope vs IP Helper RRS feed

  • Question

  • Hi @all,

    SCCM 2012 R2 on W2K8R2 Server with SQL 2012 SP1 included all CU's and Hotfixes.

    It's only for a LAB so i have installed all on one Server.

    Problem is now, that when i install W8.1 i need other bootfile than when i install W7 cause of EFI.

    How did you manage this with Windows Server DHCP? cause with Scope options i only can set one Boot File (=067)

  • Hi,

    This is exactly the reason why it isn't supported or recommended to use DHCP options instead IP Helpers should be used. Ip Helpers will assign the boot file dynamically. Moving the DHCP role to a separate server will solve it.

    In your setup you have another challenge as well, WDS in Windows 2008r2 will only support PXE boot from an uefi x64-based machine and not 32bit. http://ccmexec.com/2013/05/configmgr-2012-uefi-and-pxe-boot-support/

  • I would test it before implementing in production (especially if you have never done it before). There's nothing to worry about if it's just a lab environment though.
