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?
 Thanks.

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.

Also:

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

Hi,

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

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. 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.
