Recently we updated our JSS to 9.100, previously 9.93, and since then our DEP Pre-Stage enrollments are stalling out for about 1-2 hours (no exact times) before the actual enrollment takes place and enrollment policies kick in. There are a few other threads on here about DEP creating unmanaged computers, but none mention the 1-2 hour wait. I wondered if anyone had seen anything similar, or may have a solution that they've uncovered. I've tested this on 10.12 and 10.13 machines with the same result, so I've ruled out a weird High Sierra "thing". I've tried authentication being on and off, creating a new local admin being on and off, unchecking and rechecking all the options at the "bottom" of the Pre-Stage setup; nothing changes. The computer gets the Pre-Stage trigger, gets the computer name entered into the JSS as DEP - Serial#, but shows as unmanaged. Then magically 1-2 hours later starts the enrollment process. The jamf binary does not get installed initially, but, again after that 1-2 hour window, shows up and the machine enrolls properly. Any thoughts or suggestions would be welcome because I'm starting to get a bald patch from scratching my head!
@Look I saw that post and that actually sort of works, but the 1-2 hour thing was just me running a timer before things actually kicked off. I'd like to find a solution either way as before the upgrade we did not have this issue. Asking a customer/user to reboot after they just turned their computer on for the first time just doesn't seem right to me.
