I've got a machine that was infected with a fake antivirus that we're trying to troubleshoot. We need to get it connected to a test network for troubleshooting but it keeps getting a 169.254 IP addess no matter what. Running ipconfig /release Returns An error occurred while releasing interface Local Area Connection : An address has not yet been associated with the network endpoint. Okay, fair enough so I try ipconfig /renew But that returns An error occurred while renewing interface Local Area Connection : A socket operation encountered a dead network. We know switch, the cables and uplinks are fine; Other devices on the same switch are fine too. I've not seen that [specific error] before and running these commands hasn't helped either: netsh winsock reset catalog c:\netsh-Winsockreset.log netsh int ip reset c:\netsh-IPreset.log Has anyone seen or been able to recover from something like this?

Hi, A socket operation encountered a dead network - this could indicate a serious failure of the network system (that is, the protocol stack that the Windows Sockets DLL runs over), the network interface, or the local network itself.
