Until this directory is shared, the domain controller does not respond to DCLOCATOR requests for LDAP, Kerberos, and other DC workloads. We need to wait until DFSR finishes replicating all data from the primary member and triggers an event ID 4104 which means initial sync is completed and now both servers can replicate data authoritatively. A couple of months ago I spun up a Windows 2019 server to replace a 2008 R2 file server, and set up DFSR in order to replicate a large set of shared folders with complicated sharing and security permissions rather than try and create it from scratch, but I've never been able to get rid of the following errors on the new 2019 server, which may or may not be related: I am wondering if you have quotas set, and this issue is stemming from that.

This is the kind of bug discovered with 2008 R2 servers and hence, they have introduced new a hotfix with 2008 R2 (KB 2663685). Then you must manually resume replication with the above command. Verify all Active Directory partitions and the files in the SYSVOL are fully sourced from one or more source domain controllers and that they are replicating Active Directory as usual before you demote all of your Windows Server 2019 domain controllers in the next step.
