Microsoft released KB2908243 to deal with a situation where a Windows Server 2012-based computer on which you configured NIC Teaming has no network connectivity.
Consider the following scenario:
- You have a computer that is running Windows Server 2012.
- You configure NIC Teaming, also known as load balancing and failover (LBFO), on the computer.
- You restart the computer.
In this scenario, you may find that the computer has no network connectivity. However, when you restart the computer, network connectivity is restored.
A supported hotfix is available from Microsoft Support.
