Hyper-V VMs losing Network connectivity one by one

[fiza]

Have several VMs running on 2016 Hyper-v host. This morning 1 VM lost connectivity to the network. The others on the host were fine. I failed this VM over to our Replication Server and it starts working again. Just now another server has lost connectivity and I did the same and that too starts working again.

 

I am worried that other VMs on that server will go into the same state.

 

Any ideas why this would happen? All VMs on that server been running perfectly fine previously.

do you have nic teaming set up? ive had vms just stop talking to the network for no reason move them from the teamed nic to an "actual" nic and they worked fine without rebooting anything

We have nic teaming enabled. Its the switch independent Server based one.
