- Search for MAC addresses using an report called: “MAC – computers for a specific mac address” found under “Monitoring -> Reporting -> Reports”
- Check the SMSPXE.log stored under: /Program files/SMS_CCM/Logs, find the entry where the computer tries to PXE boot and take a note of the “Resource ID” and search for the Resource ID on “All systems” found under; “Assets and compliance -> Devices”, you may need to add “Resource ID” column before searching.
