Hi,

Thank you for your relpy.

I found some information upon pre-existing folder for your reference.

"The placement of files in the pre-existing folder on reinitialized members is a safeguard in FRS that is designed to prevent accidental data loss. Any files destined for the replica that exist only in the local pre-existing folder and were replicated after the initial replication may then be copied to the appropriate folder. When outbound replication has occurred, files in the pre-existing folder can be deleted to free additional drive space." From: https://docs.microsoft.com/en-us/windows/desktop/vss/backing-up-and-restoring-an-frs-replicated-sysvol-folder

"PreExisting – During initial sync or cloning, files with the same name and path that exist only on the downstream server move to: <rf>\Dfsrprivate\PreExisting" From: https://blogs.technet.microsoft.com/filecab/2013/08/23/dfs-replication-in-windows-server-2012-r2-restoring-conflicted-deleted-and-preexisting-files-with-windows-powershell/

Kind of vague but the simplest solution may be to move roles off, demote, reboot, promo the problematic one.

I am hesitant to move all the production server roles off, demote, reboot, promo the main production server.

The errors and warnings have gone away. Next time I have to see if the errors and warnings are repeating. Nothing to look at. I just mark one of the Community Experts answers to close.
