Taking this question a step further,
IS there a way to make two servers in a cluster communicate with each other while using Unicast with one NIC? Two NICS?
We have two front end Windows 2003 Exchange 2003 servers in an NLB using unicast. There are two NICS present. NLB is bound to 1 nic on each.
Our problem is that since these are both front ends, i would think Exchange would like to pass information between these two from time to time, but instead has to route a different way. This is noticable if you make one server a bridgehead for a connector, but not the other. A delay will occur (knowing full well that these servers need to be configured the same since they are in an NLB cluster but that is just an example).
Do I need to change to multicast after confirming my switch will allow that?
