How to remove the Hybrid Azure AD join-ed Windows Server that is Registered = Pending without rebooting servers?

Question

After following the suggested steps in enabling the HAADJ:

1. First: Targeted deployments of hybrid Azure AD join - Microsoft Entra | Microsoft Learn
2. Followed by: Configure hybrid Azure Active Directory join - Microsoft Entra | Microsoft Learn

All of my 1000+ production Windows Server 2016 – 2019 and 2022 VM are now showing like below:

This incident has caused me some trouble in manually removing by issuing the command like below with no error.

dsregcmd.exe /leave /debug

As you can see from the above, CN=Device Registration Configuration container name has been reset to blank in the ADSI edit.

However, the device itself is still not removed from the Azure AD console despite the manual efforts to delete the Registered = Pending from the https://portal.azure.com/#view/Microsoft_AAD_Devices/DevicesMenuBlade/~/Devices/menuId~/null

all of them are still listed back as Hybrid Azure AD joined after a few minutes have passed.

Any help would be greatly appreciated.

@EnterpriseArchitect, Thanks for posting in Q&A. Based on my experience, if the records are still in Azure AD, we can remove these Hybrid Azure AD joined device records in Azure AD portal.

Meanwhile, if you want to just do Hybrid Azure AD join for some devices, you can create an OU to put the users and devices you want, configure the customize synchronization options in Azure AD connect to only sync the users and devices in your specific OU.

Hope the above information can help.
