hello world! First post! Really strange issue I am having, I have about 10 VM's currently running across my 3 Node Cluster (Ubuntu, FreeBSD, Etc). I am having an issue installing Windows Server 2012R2, it gets about halfway through the install before 2 Nodes drop out of the cluster. This behavior doesn't happen when installing Linux based OS's. Any suggestions? Where should I start? Thanks!

Current setup:

3 Dell R320's with Quad gigabit Nic (Bonded, multiple VLANS)
NFS Storage for VM's and ISO's
