Answer by Atul for How do I find the DNS name of a physical Hyper-V server using remote WMIC commands? I only know the virtual servers' DNS names

The following registry key contains information about the Host server:

HKLM\SOFTWARE\Microsoft\Virtual Machine\Guest\Parameters

Some important keys are:

HostNamePhysicalHostNamePhysicalHostNameFullyQualifiedVirtualMachineName

Plus a number of settings about the Host Server’s version

So simplest way to get host server name is to run following DOS command:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtual Machine\Guest\Parameters\" /v "PhysicalHostNameFullyQualified"

As per my info, this works for many guest OS. However not sure for all. Also it needs vmtools to be installed on guest OS.

Alternatively you can issue WMI command:

WMIC /namespace:\\root\virtualization PATH "Msvm_ComputerSystem" Get ElementName, Caption

This should give you "Hosting Computer System".

Please let me know if this helps. And if yes, please don't forget to mark this as answer.
