Active Directory FRS errors
Posted on 2015-02-16
I have 3 DCs between 2 offices:
- oldDC (SBS 2011)
- newDC (2012 R2)
- remoteDC (2012)
newDC was just promoted as a domain controller. We will eventually get rid of oldDC and rely only on newDC in the main office. For now though, oldDC still has all FSMO roles as required by SBS.
I noticed that newDC had SYSVOL/NETLOGON replication errors. Right now it isn't even sharing either folder. I looked into Event Viewer on oldDC and found that it is in journal wrap state. I thought an easy fix would be set BurFlags to D2 on oldDC and newDC and set D4 on remoteDC. However, remoteDC is also not replicating because of oldDC's journal wrap state.
From what I understand, D4 should only be set on a known, good working copy of SYSVOL. Since oldDC has the journal wrap error, I'm worried about setting D4 on it. I also don't have a good, working copy of SYSVOL from a backup.
What do I need to do to resolve this? Additionally, information about backing up all data before I start trying to resolve this would be much appreciated since I don't have a known good backup.
