![]() ![]() I then started to investigate if the machine displayed in SCCM existed in active directory and sure enough, it was part of the domain. The second query did not return anything when I inputted the UUID it displays when pausing at the PXE boot screen, but, after examining the contents of SMSPXE.LOG, I was able to see the last UUID that attempted to connect which was slightly different (some numbers seemed transposed) and when I used this it returned the same exact computer as in the first query (phew!). ![]() The first query returned a machine in the database with a different name than the one I was working on but had the same MAC address (actually two MACs) and with a different UUID. In order to determine the issue, I built out the following two queries: Find computer by MAC address: select distinct * from SMS_R_System where SMS_R_System.MACAddresses = "aa:bb:cc:11:22:33"įind computer by UUID: select * from SMS_R_System where SMS_R_System.SMBIOSGUID = "AAAAAAAA-BBBB-CCCC-1234-567890ABCDEF" ![]() I had a very strange issue today as I pulled a loaner laptop to test an application I was working on – turns out the machine would not PXE boot because its MAC address was already assigned to another machine in SCCM’s database. ![]()
