Hypver V Question

Hi,

I have a Windows 2008 R2 DataCenter host Server which hosts 8 virtual machines.  I have found that when I try to ping or remote desktop onto two of them, I either get request timed out or unable to connect to remote desktop.  This is strange in that it randomly happens and a reboot will fix the issue.  The two machines in question are both Domain Controllers and so far I don't see the others displaying the same problem.  I didn't setup the Teaming (and i'm not entirely sure how it works) but I'm wondering if this is causing the issue?

Cheers

What type of virtual NIC is installed in the VM? HV or Legacy?

Is the firewall enabled on the VMs along with monitoring? Are you able to see dropped packets in the logs?

I recently had an interesting issue with a physical NIC driver on a hyper-v host which randomly stopped network traffic to different vms until a reboot occurred.

It seems the problem was with the teaming, I deleted it and recreated it and the problem has stopped.

We avoid Broadcom for so many reasons. :(

Back in the day we used Intel's PROSet software to bind NIC ports in teams. It was around v15.2 when a command line setup was delivered so we could do so on Core. Intel's teams were rock solid.

With 2012 and native teaming the need to use third party went away.
