Replication is Failing Health Critical

Hello,

Let me start by saying I am a new Admin to this organization and have no real Hyper-V experience. I have figured most things out until now. 

We have 2 sites in different states that are Hyper-V 2012 servers (site A and site B).  They are set up for HA failover locally and replication between the sites.  The previous admin set all of this up.  Our website in location A was running on a 2008 R2 vm with SQL 2008 SP3. The replication between locations worked.

I recently created a vm running server 2012, ColdFusion 11 to host the site in location A. I set the 2008 up as just the database server still running the same as previously mentioned. 

Replication between locations has failed since the day I turned on the 2012 vm.  I have not changed anything about the vm other than its IP and name, which replication doesn't seem to care about (at least that I can find).

When I look at replication health I see the following:

Virtual Machine   Name Start Date for Report Health Monitoring Interval Ending Date Replication Health: Replication State: Replication Mode: Current Primary Server: Current Replica Server: Average size: Maximum size: Average latency: Errors encountered: Successful replication cycles: Total replication cycles Size of data yet to be replicated: Last synchronized at:
Production DB 7/16/2015 4:00 7/16/2015 16:22 Critical Replication Error Primary 0 KB 0 KB 0:00:00 1 0 148 151.23 GB 6/27/2015 9:44

When I try to start the VM at location B I get this:

An error occurred while attempting so start the selected virtual machine 'Production DB' failed to change state

When I try to resume replication at location A I see this:

Hyper-V could not replicate changes for virtual machine 'Production DB': The process cannot access the file because it is being used by another process. (0x80070020). (Virtual machine ID ACD28B43-D3FA-4E36-9014-BBB309F6316

What am I doing wrong?  How can I get this working?

Any assistance will be GREATLY APPRECIATED!!!

Thank you

Are you running AV on the Hyper-V Servers?  If so, it sounds like the exclusions are extremely folder specific )thus impacting individual VMs).

This is always the first question to ask.

Also, for the replicated VM - you have to trigger a replication test.  Otherwise it should be locked by the replication service.
