GUID mis-match

Hi,

When I PXE boot a PC, I can see Client MAC Address and GUID

I am capturing MAC address and GUID with Powershell , GUID wasn't same as was in the PXE Boot Screen.

(Get-WmiObject win32_NetworkAdapter -Filter "NetConnectionID = 'ethernet'" -Property MACAddress).MACAddress  (OK)

(Get-WmiObject win32_NetworkAdapter -Filter "NetConnectionID = 'ethernet'" -Property GUID).GUID (GUID is different from the one available on PXE boot screen)

Any thoughts or maybe I am doing something wrong?

N.A.Malik
