Experienced an odd behavour when using a boot.iso with unknown computer support enabled.
If I added a computer to the SCCM console and installed the computer, the computer got the same name as I gave it when importing the computer (correct).
But when I reinstalled the same computer a second time it was named with a MININT- name instead..
Created a new boot.iso without unknown computer support (not using it anyway) and the problem went away. The computer now gets the name entered in the SCCM console every time.
