@rogalskij While I can understand that your techs want to get it imaged as fast as possible I would still suggest they take on small hurdle at the beginning and save a lot of time later on.
See if you can tell them to PXE boot and choose “Perform Full Host Registration and Inventory” instead of direct deploy. This will ask for the hostname to be used within FOG (and als set in Windows!) as well as image ID and even set all the information for automatic AD joining. At the end of registration you can tell it to schedule a deploy so it does one reboot and deploys without any further interaction.
If you set things up correctly your techs would take maybe 2-3 minutes for the full registration but after that they can walk away and it does the deploy, rename, join domain (fog-client) without any further action required.
Beside that you won’t have additional MAC flooding that single host…
