AD / SYSVOL Version Mismatch

Question

Hi,

May I know what is the proper way to replicate sysvol and netlogon folders to additional DCs if they are missing or not getting updated?

PDC : Windows 2012 Std
Additional DC1: 2012 Std
Additional DC2: 2016 Std

Answer 1

Try the non authoritative synchronization.
If you're using older FRS you can follow along here.

or for DFSR follow along here.

If missing altogether then these ones may help.

Hi,

Based on your description, there are 2012 servers in your domain.
If you run the Group Policy Modeling Wizard from the Group Policy Management Console (GPMC) snap-in on a Windows Server 2012-based DC,the error happened because one or more Group Policy Objects (GPOs) cannot be applied because of security filtering or Windows Management Instrumentation (WMI) filtering.
To resolve this issue in Windows Server 2012 R2, install update rollup 2919394.

If this still can't resolve your issue, please check if the DCs are working well , and the replication is good.
