IP Stack Not Working After HyperV Guest Restore


I had a failure on a 2008R2 guest which I had to restore from backups (we use veeam).  The restore went fine but after I fired up the guest, it can't communicate on the orginal subnet.  We use for the network this guest is on.  We have multiple vlans and if I give the server an address on any network besides the one that was statically assigned when the server crashed, it pings and works perfectly.  This particular server is a DC/DHCP/DNS for the .99 vlan so simply using the other subnet isn't really an option.

I've tried changing/adding other network adapters as well as Legacy network adapters.  No change.  I've also shut the server down, removed all NIC adapters, restarted then deleted all the TCP/IP profiles in the registry.  Shut down the server and added a network adapter again.  Same symptoms.

I would really hate to have to replace this server as it fills a few roles for this subnet and business needs but I have to get it running.  Any advice or things to try?

Might have a hidden network adapter with the static ip. Try this procedure to search for hidden (non presant) devices

I was under the gun to get things working and tried spinning the guest up on a stand alone hyperv host outside the cluster.  it worked great first go around.  It was something at the host level that was having the problem.
