It will cause DFSR SYSVOL migration to fail. Both domains are running FRS with a mixture of Windows 2012 R2 & Windows 2016 DCs. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. When you then run DFSRMIG.EXE /SetGlobalState to migrate to DFSR, all upgraded Windows Server 2019 domain controllers are stuck in the Start phase and cannot complete the transition to the Prepared or later phases.
I wanted to know if i can remote access this machine and switch between os or while rebooting the system I can select the specific os.

Keywords: Classic Good to know that there's progress being made at least. Whenever we create a DFS namespace and DFS Replication group, the namespace and replicated group are stored into the active directory domain partition and if AD replication is failing, then the changes are not replicated to the remote domain controller, hence the DFS server in that site could not get those changes and could not initialize initial sync (one way sync). This command shows you the current replication state of DFS-R in regard to its DFS replication group partners. I rolled back to Global State 0 and will demote the PDCe after transferring the roles to another server, then begin the migration again.

Demote all Windows Server 2019-based domain controllers to member servers. To force a DFSR server to check with Active Directory (AD) for configuration/replication changes, use the DFSRDIAG command with the POLLAD parameter, as the following example shows: C:\Users\savadmin>dfsrdiag pollad Since it can't populate its SYSVOL, any changes to fix the user rights won't be applied.

DFSR has many advantages over FRS, including being far more efficient in the data it replicates. Promote one or more Windows Server 2008 R2, Windows Server 2012 R2, or Windows Server 2016 domain controllers in that domain. DFS recovery is turned on and the backlog is growing since no replication is currently occurring. If you did not set the above registry setting on a 2012 domain controller with a. value and the DC suffered an unexpected shutdown, the Sysvol folder stops replicating because of a dirty shutdown and you would get event id 2213 in the DFSR logs. The DFS Replication service failed to initialize replicated folder C:\Windows\SYSVOL_DFSR\domain because the service detected that one of its working folders overlaps a Windows system folder. Event 4102 states that DFSR has started rebuilding the DFSR database. DFSR has significant built-in instrumentation for troubleshooting and debugging, including considerable event logging and a large number of highly verbose debug logs (1000 debug logs maintained under compression by default in Win2008 R2, at the second to highest level of verbosity by default) A table After 36 hours, all 66 DCs are still in the 'Waiting for Initial Sync' state.
