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.
