Hi, I'm running Win 2012 R2 Hyper-V

I had a server with some connectivity issues.  A stale AD account object.   I removed the machine from the domain and rebooted.   Now there is no network adapter object.

It shows in the VM settings and when I log on to the VM the device manager shows the adapter. Running IPconfig shows the address, etc. 

I disabled and enabled the adapters in device manager, rebooted but the adapter is a no show in the Network app in the control panel.  

Anyone experience This?

Yes.
Add a new NIC
Clean out the old one.
Check what updates/ AV was installed.

Hi Joe.  I did that four times.    I rebooted the host as well. The other VMs are working.

What's the guest OS?
Is it a new build, imported/restored from an earlier hyper-v host (2008/ 2008 R2) or some kind of a P2V (P2V/ restore from a backup etc)?
What happens if you start it in Sage mode with networking?
What happens if you add a legacy NIC?
Can it ping localhost/ it's IP and the host?
Have you tried reseting the network stack on the guest?
WAG question but are all the guests on the same virtual network?

I started it unconnected w/o Network adapter.
Then toggled it back.
Can't ping anything.

I'm moving the hard disk to another Win 2012 R2 host.  It's not using a legacy nic.   After loss of most of the day, it's beyond the time limit.

All the guest machines were on the same virtual network.  It's a lab.  I have a lot of testing to do and with Dynamics I need a lot of machines.

Update: This is my lab.  So............ the VM is dead. I killed it.  It stole a day from me.  That's a lot of time in the IT world.  The databases on this SQL server were from older version of CRM so it's not a big loss. 

Rebuilt new SQL server and application server between yesterday and today and it's finally running.


I did try to move it but that failed as well.

Thanks for all your help everyone.
