SCCM PXE Boot Deep Dive – Backend Flow & DP Migration
I’ve used both approaches depending on the customer environment, but nowadays IP Helpers are usually the cleanest and most reliable option for PXE.
I still had to use DHCP Options in some smaller or legacy environments, but as you mentioned, most PXE/OSD issues end up being related to networking or security rather than SCCM itself.
And it’s not only about directing clients to the correct DP. I’ve seen many cases where the ports and communication required after PXE during OSD were not fully configured by security/network teams, causing random failures later in the task sequence.
From my experience, before an OSD issue reaches the DP configuration level, it usually starts somewhere in the network or security layer. Even when all requirements are shared with those teams, there’s almost always one missing configuration somewhere.
