Solution Steps
- 1 Open PowerShell as Administrator.
- 2 Run 'Get-ClusterNetworkInterface' to list all existing network interfaces in the cluster. This shows you what interfaces are already defined, helping you spot duplicates.
-
3
If you see an interface with the same name or IP address, you can remove it using 'Remove-ClusterNetworkInterface -Name
'. This clears the duplicate so you can create a fresh one. - 4 If the interface doesn't appear but the error persists, check for orphaned resources using 'Get-ClusterResource'. Sometimes old resources linger and cause conflicts.
-
5
After cleaning up, try adding the interface again using 'Add-ClusterNetworkInterface -Name
-Network -Address '. This should succeed now that the duplicate is gone.
