Entra Domain Services domain controller has stopped GPO syncing
We are using EntraIDDomainServices for our domain controller. We've been doing so for years. This week we saw that Group Policies were no longer being applied to users.
When we run a GPUPDATE /FORCE we get the following
========= Computer policy could not be updated successfully. The following errors were encountered: The processing of Group Policy failed. Windows attempted to read the file \\<domain>\SysVol\<forest>\Policies\<policy ID>\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following:
a) Name Resolution/Network Connectivity to the current domain controller.
b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller).
c) The Distributed File System (DFS) client has been disabled.
=============
When I browse \\<domain>\SysVol\<forest>\Policies\ I see all the policies I expect, but there is no gpt.ini in any of them.
When I look through the Group Policy Management Console, I see all of my policies, but none of them display the registry keys or shortcuts we've configured them to deploy.
Help? This is a massive concern. It's been working for years but just stopped this week...
