byrmccull Posted March 27, 2014 Report post Posted March 27, 2014 I am experiencing difficulties getting machines (both physical as well as virtual) to PXE boot across my subnets. ANY information or assistance would be greatly appreciated! I currently have SCCM 2012 R2 installed on Server 2008 R2, with several subnets. I need the ability to have the subnet machines PXE boot to install a fresh image. This is working wonderfully so long as I the virtual or physical machine is within the base domain, but refuses to work at all on the subnets.

tmcmanus28 Posted March 28, 2014 Report post Posted March 28, 2014 Depending on the setup, but it sounds like a routing issue. PXE request are broadcasted and routers drop broadcast thus not letting PXE cross subnets or VLAN's. This can be resolved by adding an ip helper address configuration to your router to forward PXE broadcast request. This also applies to layer three switches. Here is a link to an article that explains how it works and some options to help resolve it http://verbalprocessor.com/2011/08/19/pxe-booting-and-ip-helper-address-resources/ Quote Share this post Link to post Share on other sites More sharing options...
