I am fairly new to VMWare so we hired a consultant to help configure our VM network and create a cluster of 3 hosts. We also invested in a SAN that has 4 10GB NIC's and a 10GB switch to connect to the VM Hosts. On one of the VM hosts we have an SQL 2012 server and it has 3 virtual NIC cards assigned to it each with their own IP on the same subnet.
I have been reading on the net that this is acceptable however when I ping the server it returns any one of the three addresses which I guess it is ok but when I look at the System logs I see errors stating "A duplicate name has been detected on the TCP network. The IP address of the computer that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state." this doesn't seem right however if multiple IP addresses can be added and used on one machine then I would think this error can be ignored. Is that right and if not how do I correct this issue?
