I keep getting an error 6408 on my domain controllers. I have tried multiple ways of disabling the file replication services and forcing it to replicate through authoritative and non-authoritative means. when I have everything disabled and I run repadmin it comes back with no errors but as soon as I start the service back up I get error 6408 again.
ERROR:
The DFS Replication service failed to initialize replicated folder C:\Windows\SYSVOL because the service detected that one of its private folders overlaps with an existing replicated folder. This is an unsupported configuration.

Hmm, you just describe the exact method I used. It let me set up a 2019 server and add it to a 2003 forest, now I have to start from scratch.

As mentioned, that should not have been possible but regardless it sounds like your only hope is to restore from a backup, do the prerequisites and try again.

Restore a backup of a corrupted system, not much point. If I can't get what I have working then it's start all over from scratch and build it right.
We've no idea, but if it was corrupt before the 2019 domain controllers were added then this just adds complication. Please don't forget to close up the thread by
