Issues with duplicate hardware identifiers in 1610

[e5franson]

I just installed 1610 on our lone SCCM server. Added the duplicate hardware identifiers features and added our 3 USB NICs to the whitelist. My problem now is that I cant get PXE boot to get going for any of my USB NICs. PXE boot aborts as if the device is still in SCCM (I went through and deleted the devices associates with the MAC address of the 3 USB NICs). When I check the smspxe log, I see that it reports that the device is in the database, and that no advertisements were found. Am I missing something?

Ended up being an SMBIOS GUID being registered to a PC that was imaged before the upgrade. Created a collection using the query rule below to locate the machine that had picked up that GUID. It had updated the MAC but for some reason held onto the GUID.

 

select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.SMBIOSGUID = "Device SMBIOS GUID"
