Hello all, I have two servers with two fiber NIC's each that I am planning to use for load balancing. I will be using MICROSOFT NLB. Can I create two NLB by using NIC1 for first NLB and NIC2 for second NLB? My goal is to have two virtual names for high availability. To brief it: Internal DNS has a A record for HAhost1, with FQDN as HAhost1.dom.local (only internal access with no availability through internet) Internal DNS has a A record for HAhost2, with FQDN as HAhost2.dom.com (will have external access through internet) Server1 has two NICS. They are named as NLB1 and NLB2. Server2 has two NICS. They are named as NLB1 and NLB2. From NLB mmc, I connect to Server1 and select NLB1, type in the IP address of the HAhost1 and the FQDN as HAhost1.dom.local. Then I add Server2 with NLB1 as part of this cluster. Again for second NLB, From NLB mmc I connect to Server1 and select NLB2, type in the IP address of the HAhost2 and the FQDN as HAhost2.dom.com. Then I add Server2 with NLB2 as part of this cluster. Please advice whether this setup will work. Thanks in advance.Tom

Quite disappointed by not seeing any suggestions here. Tom

Hi Tom, Thanks for posting here. > Can I create two NLB by using NIC1 for first NLB and NIC2 for second NLB? NLB can be bound to multiple network adapters, which allows you to configure multiple independent clusters on each host. > My goal is to have two virtual names for high availability Actually NLB does support multiple, virtual IP addresses on one NLB cluster. So why not just create one NLB cluster , add multiple virtual IP addresses and set DNS records for it?
