DFS-R Replication between Windows Server 2012 Hyper-V VM's

I have 2 Hyper-V Virtual Machines both running Windows Server 2008 R2. Virtual Host Server is also Windows Server 2008 R2. I have AD DFS Replication set up between these servers and everything checks off properly and replication starts as scheduled, but files are not transferred from one server to another. When I run replication reports, no errors come up either.

 I tested same setup on physical servers and works like a charm, but seems as something is blocking file replication on VM's.
 Any ideas?

Correction: VM's are running Windows Server 2012; VM Host is Windows Server 2008 R2
Both VM's are in the 2 node NLB Cluster.

Are there any errors in the event log relating to DFS?  Have you looked in the DFS-R Logs, they live in C:\windows\debug.


1. how big are the VM volumes where DFS is replicating to/from?
1a. how does that compare to the physicals you tested on?
2. how much data is to be replicated?
3. do you have a large enough staging area for DFS?
4. Have you run a Health Report in DFS Manager

Lev KaytsnerAuthor Commented:

1. Each VM C:\ drive is 100GB
1a. Average physical server C: Drive is larger then 100GB
2. Directories that need to be replicated have various sizes, from 8MB to 800MB
3. Each volume has almost 50% of available space
4. Health Report shows this:

Backlog calculations cannot be performed because the reference member returned zero replicated folders

Here is the info from debug logs, I see following:

Cluster service is not installed or configured. Skipping the VCO polling

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Just updated AD schema to Windows 2012. My AD is 2008 based, but it did not make a difference.

The problem was in DFS-R Jet database corruption after server was improperly shutdown. " Dirty Shutdown State"
Microsoft had to go in and restore database.

Please close the case

Nobody else helped. I had to reach out to Microsoft for help and pay their support rate.
