| | Action | | :--- | :--- | | 1. Network Driver | Obtain and inject the correct WinPE-compatible NIC driver for your client model into your SCCM boot image. | | 2. DHCP Configuration | Remove DHCP Options 66 and 67. Use IP Helpers on your network routers and switches. | | 3. Boundary Groups | Ensure the client's subnet is part of a valid SCCM boundary associated with a boundary group containing your PXE DP. | | 4. Task Sequence | Verify the OS deployment task sequence is actively deployed to the client or an "Unknown Computers" collection. | | 5. PXE Role | If all else fails, reinstall the PXE role on the distribution point. |
