SYMPTOMS

Consider the following scenario:
  • You install the Failover Clustering feature on a computer that is running Windows Server 2008.
  • You configure several virtual adapters to share one MAC address on the computer.
  • You run the cluster validation wizard on the computer.
In this scenario, the validation fails and you receive the following error message:
Verifying that there are no node adapters with the same EUI-48 physical address.

Found duplicate physical address <address> on node servername.domainname.com adapter Local Area Connection <number> and node servername.domainname.com adapter Local Area Connection <number>.

CAUSE

This issue occurs because the cluster validation wizard incorrectly identifies multiple virtual adapters that have the same MAC address as a configuration error.
