Can anyone else confirm this on Server Core 2012
1. Set a Static IP address and Static DNS = works fine.
2. Using Corefig try and rename the default "Ethernet" to anything = fails
The powshell window in the background flashes with errors in a loop too fast to see, then the app crashes.
I can successfully rename the NIC with the following powershell commands manually.
Rename-NetAdapter -Name "Ethernet" -NewName "MyNewName"
