Hi all, I'm having an odd issue on a 4 node cluster, which was working fine until recently. I have patched/rebooted 2 of the nodes and now I am having network issues with certain VMs. If the VM is part of a windows NLB Cluster it completely loses network connectivity when placed on either of these hosts.
The fabric is fine, although it did have 'non compliant' on the switches on these hosts which I have remediated. The cluster validation wizard gives me no errors. These VMs are set to have static MACs and have a classification of Network Load Balancing on their virtual switch.
Just to add to the issue - when the VM error occurs, SCOM alerts the following:
The system detected an address conflict for IP address
0.0.0.0 with the system
having network hardware address <MAC ADDRESS>.
Network operations on this system may
be disrupted as a result.
Any ideas much appreciated as I have run out of places to look. Thanks. Carl.
