View Full Version : Two NICs on Hyper-V on the same subnet

12 Mar 2012, 07:12 AM
I have several VMs on a hyper-V (http://www.vpswebserver.com/windows-vps/what-is-windows-vps-and-hyper-v-vps), one of them is SQL2k8. I had 1 network card, used for an external virual network which was shared between the 4 VMs.

To improve my network, I added a 2nd NIC, created a 2nd external virtual network and gave it a static IP.

So 1st NIC IP is, the 2nd is

In the sql VM setting I changed the network to use this 2nd virtual network. It gets the right configuration but when I try to connect I get very strange behaviors. I tried some pings, getting a lot of "Request time out" or 1 a reply with several Request time out like thgis :
