We have one problem related to the DNS hostname resolution in teh datacenter devices.
The servers have multiple NIC cards, one of them is primary production NIC (10.10.3.X) and another one is for backup (storage-backup) network with subnet 10.10.200.X). The backup subnet is entirely separate and we are not routing this subnet in the datacenter devices.
The problem is when I try to connect to any server from one of my remote site using hostname it does not respond as the hostname resolves to 10.10.200.X IP address. This problem is not happening always, just intermittant. Is there any way I can stop the backup NIC IP to participate in DNS queries? What do you think the problem could be?
Thanks and regards,
