HyperV 2012 Core - External Virtual Switch Not Working

-

setup new hyperv 2012 core installation on dell r720.  when setup first 'external' virtual switch, virtual host nic creates gets 169.xxx ip address , none of guest vms can access internet.  worked fine in test environment i'm frustrated trying figure out changed.

i tried verify nic driver or extended network settings etc since apparently can't use device manager anymore have no idea how check/update beyond vague references 'do in powershell'.

any ideas?  i tried assigning secondary nic external switch instead of sharing primary , still no luck.  arg!

looks same issues (w/out resolution) here:

i love silly ones.  :) frustration , matter of mistaken network adapters.

though in own defense, if ms had better management tools in place, i'm betting (the 3 people had troubleshooting, including hyperv consultant missed - assumed more complex issue) have caught sooner.

windows reason assigned network adapter names , descriptions in out of sync manner:

hyperv assigns nic based on description , not name (which correct), assigning wrong port virtual switch. since sconfig shows active nics, resulted in odd 'dual' nic behavior seeing.

bill: [lawnmower won't start] karl, see if can figure out what's wrong this. won't crank , seems put right.

karl: ain't got no gas in it.
