I am running Windows Server 2012r2 on a Dell R720. I have HyperV installed and working in my environment. Periodically I won't be able to access a virtual from the network. I can't RDP or ping the virtual, but I can see that the virtual is up and running from the HyperV console. I can log into the virtual and ping other servers on my network.
I have virtual host that I can't ping or RDP to it but I can't RDP and ping virtuals running from it.
