Intune Enrollment problem solver script thingy

retry-intune-enrollment.ps1

# Clean out MDM registration info from machine, in attempt to fix Intune enrollment problems with Windows 10
# after a user reboots, the enrollment process should kick off again.
# This special edition, also disables workplace join, as an attempt to mitigate issues with devices previously AAD Registered.
# This script has fixed Error codes 0x80180023 and 0x8018002b at some of my customers sites, even without reboot in some cases.

# Should be run as system user

#Disable workplace join if that is happening beyond your control.
#Get-ScheduledTask -TaskName "Automatic-Device-Join" | Disable-ScheduledTask
#Get-ScheduledTask -TaskName "Recovery-Check" | Disable-ScheduledTask

#you can try either one of the two following actions afterwards, or both (test test test)....

#Remove AAD registration from Machine.
& $env:WINDIR\system32\dsregcmd.exe /leave

#Re-run deviceEnrollment
& $env:WINDIR\system32\deviceenroller.exe /c /AutoEnrollMDM

The issues can arise from computers that have mistakenly been workplace joined (Azure AD Registered) etc.

Try and mix the commands around, I found that it's a trial and error thing, and waiting is also key, sometimes you need to do the /leave command, and then wait like 8 hours, before restart.
