Hyper-V cluster: Unable to fail VM over to secondary host

I am working on a Server 2012 Hyper-V Cluster. I am unable to fail my VMs from one node to the other using either LIVE or Quick migration.

A force shutdown of VMHost01 will force a migration to VMHost02. And once we are on VMHost02 we can migrate back to VMHost01, but once that is done we can't move the VMs back to VMHost02 without a force shutdown.

The following error pops up:

Event ID: 21502 The Virtual Machine Management Service failed to establish a connection for a Virtual machine migration with host.... The connection attempt failed because the connected party did not properly respond after a period of time, or the established connection failed because connected host has failed to respond (0X8007274C)

Here's what I noticed:

VMMS.exe is running on VMHost02 however it is not listening on Port 6600. Confirmed this after a reboot by running netstat -a. We have tried setting this service to a delayed start as suggested here:

I have checked Firewall rules and Anti-Virus exclusions, and they are correct. I have not run the cluster validation test yet, because I'll need to schedule a period of downtime to do so.

Anyone have any suggestions on how to troubleshoot this particular issue?

Thanks,
