@vince-villarreal If your image contains the FOG Client, which is sounds like it does, simply disable the service, disjoin the domain, capture the image. In terms of SYSPREP, you would have your setupcomplete.cmd set to enable the fog service as the last thing it does. Then you can start the service or restart the machine.
So basic steps:
Create your layout of software/OS, etc…
If machine is to be constant master image maker machine, don’t allow it to join the domain (can be setup in the GUI under Hosts->Edit->Active directory->Join Domain)
Install FOG Client.
# If sysprepping
Disable fog client service.
Sysprep Machine.
Fully shutdown machine.
# End sysprep steps
Capture image.
