@Sebastian-Roth Thanks for your reply. Interesting to know, how FOG is starting up. As mentioned before, I think the issue was, that DHCP-Server couldn’t hand out a dynamic IP. So one of the last two requests seem to request with the wrong MAC address, as my DHCP has fixed reservations for the right MAC and should have delivered the right IP. Anyhow, as also mentioned before, the bug (or feature) is not occuring anymore as i freed up some space for dynamic hand out. So sorry, but I can’t provide additional Screenshots/Informations…
