Advice : Cluster Configuration
If you have a Microsoft Cluster using MSCS then please ensure that your heartbeat adapter, usually the one with the private IP like 192.168.0.1 is set to Internal Cluster communications, the screenshot below is NOT correct for optimal MSCS operations.....
Failing to chnage this setting will not result in a cluster not working, but it will be harder to diagnose issues when the occur as if the issue is linked to network traffic then you will need to debug/packet sniff both network adapters instead of just one!
