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.
