To add to this, the SysVol contains the domain public scripts and part of the 
Group Policy “stuff”.  A GPO consists of two parts: a Group Policy Container 
(GPC) which is stored in AD, and a Group Policy Template (GPT) which is stored 
in the SysVol folder.  The GPC is replicated via AD, whereas the GPT is 
replicated via either FRS or DFSR, depending on what the SysVol replication 
method is set to.

Define "AD Replication."  I suspect you are thinking of FRS from the 2000/2003 
era of ADDS:  
http://technet.microsoft.com/en-us/library/6405fa66-e47b-4e17-b602-7015d6052c00

"File Replication Service (FRS) is a technology that was originally introduced 
on Windows 2000 Server to replicate Distributed File System (DFS) folders and 
the SYSVOL folder on domain controllers."


"FRS has been replaced in Windows Server 2012 R2, Windows Server 2012, and 
Windows Server 2008 R2 by DFS Replication for replicating DFS folders and for 
replicating the SYSVOL folder."
http://technet.microsoft.com/en-us/library/cc771058.aspx
Now if indeed you did mean AD Replication, then the answer is no, it did not, 
does not, will not.  This is what AD replication is about:

Someone correct me if I'm wrong but isn't replication of SYSVOL handled by AD 
replication already?

I had some questions and need some advice regarding recovering from a “dirty 
shutdown” on both/all of DCs in a domain that are using DFS-R for both the 
SysVol folder as well as a file share.

Background
I am helping a new environment that is experiencing problems where Group 
Policies are not applying correctly.  Upon closer inspection, I learned that 
DFS-R is not correctly replicating the contents of Sysvol.

Setup

•         2 Windows Server 2012 Standard (not R2) Domain Controllers at 2008 R2 
domain and forest functional levels.

•         Sysvol replication is being done by DFSR (both server’s DFSR 
migration state is at “eliminated”)

•         Both DCs are also file servers and use DFSR to replicate the “My 
Documents” file share between the two servers.

Error Messages and Symptoms

•         Event ID 2213 started to appear on 5/4/2013 on DC1, and on 4/30/2013 
on DC2 about once a month in pairs for both the C: and D: indicating:
“The DFS Replication service stopped replication on volume D:. This occurs when 
a DFSR JET database is not shut down cleanly and Auto Recovery is disabled. To 
resolve this issue, back up the files in the affected replicated folders, and 
then use the ResumeReplication WMI method to resume replication.”


•         GPMC reports that the GPO versions are not in sync.



•         The Sysvol folders do not have the same number of GPO folders.

Potential Resolution
From the event log as well as some reading I’ve done, it appears that I need to 
back up the Sysvol files and run the following for each of the 2 volumes:
wmic /namespace:\\root\microsoftdfs path dfsrVolumeConfig where 
volumeGuid="GUID" call ResumeReplication

And since it’s been more than 60 days, it appears that I will need to change 
MaxOfflineTimeInDays to allow this server to perform the recovery process.
Questions

1.       Am I on the right track to solve this problem (with what I mentioned 
in the “Potential Resolution” area, or are there different steps that I should 
be taking?  If there is any other information that I need to be aware of, 
please let me know.

2.       Since both/all of the DCs have this problem, will running these 
commands pose any problems?  I assume that I will need to run these commands on 
both DCs?  I plan to run them about a day apart.

3.       Since this server is also a file server that has a file share being 
replicated with DFS-R, will I need to take any special precautions during this 
recovery?

Any help/advice would be appreciated.  Thanks!
