I have a a strange situation here.
I have two Hyper-V hosts. One is Joined to the Domain and everything works well Ping: VM-to- Host, Host-to-VM & DNS/AD. The second host is not joined to the domain (Everything works well on Private Group) as soon as I join it to the domain, VM cannot ping host/DNS and Host cannot ping VM. This is the same domain the 1st one is joined to. Static IP address assigned.
I have looked for solutions, tried to ensure it's not a GPO issue or a Firewall issue. Rebuilt the host, rebuilt the Virtual Network adapter and even upgraded the OS from Win Server 2012 R2 to 2016 no luck.
