Hyper V VM NIC stopped working correctly.

Posted on 2010-09-09
Last Modified: 2013-11-06
I setup a Windows 2008 Hyper V Server with only one of the two ethernet NICs connected  and setup a few test VMs. I added memory to the server and accidently plugged in the wrong ethernet port that was default DCHP without knowing. I started the Windows 2008 Sever VM and logged in and notice the NIC lost it's static IP and now DHCP , setup static address and  was ask to delte the old NIC config, and I just clcik OK and proceeded, then notice IP config did a gateway address when it was configured in the IP V4 TCP properties. I checked the Hyper V server virtual NIC and saw I need to move the cable to the Hyper V server NIC with Static IP, but the Windows 2008 Hyper V VM NIC seems to work but I still cannot get the internet browser to work and IPCONFIG still has no gateway address. Any suggestions?

Could you send a "netsh interface ip show config" of Hyper-V Host and of VM as a list of virtual switches (network configuration on Hyper-V Manager) ?

I noticed when I click details on the LAN connection on the VM with the connection problem I see TCP autoconfiguration is enabled with a different IP address than the statice IP I entered.

you may have to tear down your virtual iinterfaces on the host and rebuild them.
