how to find duplicate mac address in sccm

However if you have more than one machine with the same UUID it will just look at the last machine added to Configuration Manager with that ID. When the machine tries to boot from PXE the Windows Deployment Service looks at the UUID to see if there is any deployments available to that machine. Pretty unimaginative aye? This is where the problem lies. However once I tried a machine with a unique UUID I found out that there was no problem with the deployment server but a problem with the machines themselves. At first I assumed a problem with the deployment server as I hadn’t by this point successfully deployed an OS using Configuration Manager. So it took me a bit of time to work out what the problem was. Unfortunately the first set of machines I was working with (yes you guessed it!) was a set of ASUS machines. Although I am yet to come across a duplicate MAC address I have come across plenty of duplicate UUIDs. However in the real world this isn’t always the case. In theory every machine is supposed to have a different UUID a bit like every machine is supposed to have a different MAC address which is unique to that machine. This is the problem where if you have more than one machine with the same UUID ( Universally Unique Identifier) also known as a GUID (Globally Unique Identifier) it becomes a massive pain when booting from PXE to deploy an OS. I first came across this problem when setting up operating system deployment through System Center 2012 Configuration Manger.

It’s a bit of a gem I found and anyone who works with Configuration Manager especially if deploying operating systems should know about. WMIC PATH WIN32_ComputerSystemProduct GET 'UUID' to see if yours is the same as mine.This is a topic I have been meaning to post about for a while. Run this in a command prompt in Windows OS:

These numbers are suppose to be unique to each device in the same way the MAC address is unique to the NIC. the other issue I am concerned about is duplicate UUID's If anyone else has these device please post the UUID: I am trying to test the UP-Board Make : AAEON, Model : UP-CHT01 ' for mass deployment in our test environment via SCCM, the first issue is being address about NIC PXe boot support in another thread here.
