I have a 2 node cluster that's been running fine for a while.
yesterday node 1 was reported failed. I went to Cluster Core Resources on the Failover Cluster Manager console, and try to bring it back online. It failed with this error:
Windows has detected Ip address conflict
Another computer on this network has the same IP address as this computer. COntact your network administrator for help resolving this issue. More details are available in the Windows system event log.
So, i went to look at the windows system event log:
and this is what i find:
The system detected an address conflict for IP address 10.111.14.17 with the system having network hardware address 00-21-65-a0-d9-60. Network operations on this system may be disrupted as a result.
that is super weird!! because the mac address listed is the exact mac address of NODE 1. how can it be conflicting with itself???
