hyper-v core server no active network adaperts found

I am running server core 2008 r2.  I was running fine until i installed a virtual Os and tried to bing to the network adapter.  After this i lost connectivity.   All adaperts show on ipconfig /all.

i disabled the three virtual adapters.  In the Sconfig under adapters i get "No active adapters Found"  I am unable to get any network activity.  using netsh i can see the enabled adapters.  The server has link.

any ideas.

Did Hyper-v take the whole network adapter or just sharing it ?

Are you trying to connect from another computer on the network or just from server to VM ?

It may need a DNS/DHCP server/service running.

Re-enable virtual adapter.

Check host names and IP addresses. Two servers (or VM's) cannot use the same IP or host name.

thats not the case.  when i created a external virtual adapter the server lost network connectivity.  The virtual adapters were reenabled.  The ipv4 service is still not starting.  I cant add ip.
It sounds like you did not check the box to "Allow management operating system to share this network adapter".

Try this:

On the host machine, open Hyper-V manager.
Select "Virtual Network Manager" in the right-hand pane.
Select the Virtual NIC (the one that is bound to the Physical NIC.)
Check the box to "Allow management operating system to share this network adapter".
Re-enable the virtual NICs and boot the VM.

that was not the case.  But it would prevent what happened.  i did not check and it blew out the ipv4 settings and cant add any ips now.  All the controllers are null.  I have since reinstalled this server.
