SCCM PXE Boot Deep Dive – Backend Flow & DP Migration

SCCM PXE Boot Deep Dive – Backend Flow & DP Migration

I recently worked on a Distribution Point migration and noticed PXE requests were still routing to the old DP due to DHCP/IP helper configuration.

I put together a deep dive explaining:

PXE flow (DHCP and TFTP sequence)

Role of Distribution Points

What changes during DP migration

Common failure points

One key takeaway:

PXE issues are almost always network and routing related, not SCCM itself.

Curious how others are handling PXE in large environments.

Are you standardizing on IP helpers or still using DHCP options?
