Providing a list of hardware identifiers that Configuration Manager ignores for the purpose of PXE boot and client registration, helps to address two common issues.
Many new devices, like the Surface Pro 3, do not include an onboard Ethernet port. Technicians use a USB-to-Ethernet adapter to establish a wired connection for purposes of operating system deployment. However, these adapters are often shared due to cost and general usability. Because the MAC address of this adapter is used to identify the device, reusing the adapter becomes problematic without additional administrator actions between each deployment. To reuse the adapter in this scenario, exclude its MAC address.
While the SMBIOS attribute should be unique, some specialty hardware devices have duplicate identifiers. Exclude this duplicate identifier and rely on the unique MAC address of each device.
To add hardware identifiers for Configuration Manager to ignore
In the Configuration Manager console, go toAdministration>Overview>Site Configuration>Sites.
On theHometab, in theSitesgroup, chooseHierarchy Settings.
On theClient Approval and Conflicting Recordstab, chooseAddin theDuplicate hardware identifierssection to add new hardware identifiers.
