On Windows Server 2012 R2 Host / Hyper-V Windows Server 2012 Node - ONLY
We are getting errors with DNS on Hyper V Nodes - Event ID 8015, and NSlookup shows no entry etc.
Hyper V host is fine and connection from the Node to the host is fine - including ping by name.
But DNS connection from the Node to the domain is not working.
On the DNS server we get error 4015.
First time a reboot of the Hyper V host and Node - fixed the issue, but this time we had to do that plus restart the DNS service on the prime DNS server.
Over 20 other servers all fine, DNS is fine - seems to be only Hyper V Nodes.
Both Host and Node patched to latest etc
