Windows Server 2008 – Local Area Connection disappeared from ip interfaces

networkingwindows-server-2008-r2

I have a Windows Server 2008 R2 machine.
Local Area Connection isn't working anymore, the interface exists but it doesn't as an ip interface.

C:\Windows\system32>netsh int show int

Admin State    State          Type             Interface Name
-------------------------------------------------------------------------
Enabled        Disconnected   Dedicated        Local Area Connection


C:\Windows\system32>netsh int ip show int

Idx     Met         MTU          State                Name
---  ----------  ----------  ------------  ---------------------------
  1          50  4294967295  connected     Loopback Pseudo-Interface 1

If I try to assign an IP Address I get this:

C:\Windows\system32>netsh int ipv4 set address "Local Area Connection" static XX.XX.XX.XX XX.XX.XX.XX XX.XX.XX.XX
Element not found.

What happens? Windows has lost network configuration?
I've also tried to reset ipv4 and ipv6 networking using netsh but still nothing…

According to your gist, the adapter is disabled. Try this in PowerShell:

$adapter = Get-WmiObject -Class Win32_NetworkAdapter -filter "NetConnectionID='Local Area Connection'"

You should have the adapter available as object $adapter; to verify this use:

Write-Host $adapter.Name

It should print the name of the physical adapter, "Intel(R) I210...". If you have the correct adapter, use:

$adapter.Enable()
