Hi!

Is this a standalone setup or a cluster? What is the OS of your Hyper-V hosts and what is the build version of VMM 2016?

Best regards,

standalone setup.  Hyper-V is on Win Server 2012 R2 Datacenter.  VMM version is 4.0.1662.0

Okay, you are running the RTM version. There's been other cases with the same problem as you but different errors.

Are the Server 2012 R2 fully patched? You could also try to install the latest RollUp 5 of VMM to see if it helps.

Best regards,
Leon

Hello kevscom888,

On the Hyper-V host, please open the Hyper-V Manager, and check out the virtual switch settings from the Virtual Switch Manager, and make sure the following option has been enabled for the external virtual switch.

Allow management operating system to share this network adapter

By the way, please install the most recent update for the VMM server.

Best regards,

Andy Liu
