Windows Server 2012 R2 Standard Edition (GUI) is installed on Physical Server Dell R730 and three VMs are running on it after installing Hyper-V roles.
Today, an issue reported. VM that is hosted on this particular host machine is not accessing on network. When i check it that VM was up and running but network traffic was not passing from its one virtual network adopter out of two.
I Un-selected its network adopter from Hyper-V Switch and set it on no connected through Hyper-V Manager Console and then re-select it onHyper-V switch.
Problem has been resolved and VM has been started to access from network but i could not find out the root cause that why this problem was occurred.Actually, i want to find out root cause so that issue can be fixed out permanently in future.
Note:- Broad-come Network Card is installed on Physical Server. Latest drivers are also installed but VMQ is disabled on Physical Network Adopter
