Active Directory Lightweight Directory Services deleted DFSR databases to initialize SYSVOL replica during a non-authoritative restore.

Active Directory detected that the virtual machine that hosts the domain controller was reverted to a previous state. Active Directory Lightweight Directory Services needs to initialize a non-authoritative restore on the local SYSVOL replica. For DFSR, this is done by stopping the DFSR service, deleting DFSR databases, and re-starting the service. Upon restarting DFSR will rebuild the databases and start the initial sync.
