Exclude a Mac Address from SCCM DDRs Reuse the same NIC for multiple PXE

Reuse the same NIC for multiple PXE

In order to reuse the same NIC for multiple PXE (such as OSD on sur Surface Pro using a single USB to Ethernet adapter), you have to exclude to MAC address.

Why you have to do that? the answer is simple! if a device is registered with the mac address of the USB to Ethernet adapter, this usb Network can’t be used on additional devices to deploy windows using PXE boot.

To fix this issue you have to exclude the MAC address of usb to Ethernet Adapter by modifying the following registry Key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftSMSComponents SMS_DISCOVERY_DATA_MANAGER

Edit the value of “ExcludeMACAddress” and add the Mac address with the appropriate format (letters in uppercase and the: char after all to digits ex such as 50:2A:C6:FE:AA:9C

This Registry Key must be modified on SCCM primary server.
