IIS 7, NLB Clusters, and Site IP Address Bindings
Posted on 2012-09-04
When binding a site IP address in IIS 7 on a machine that is in an NLB cluster is there a way to bind to the specific shared NLB cluster IP address ? I believe that is how it was done in IIS 6 and the Windows Server 2003 NLB clusters (i.e. the site would be bound to the shared NLB address from within IIS 6) - but for some reason within IIS 7 the only option is to bind All Unassigned or the unique cluster host IP address that only that one machine uses (as opposed to the shared IP addresses between or among the NLB hosts within the cluster). The only option there seems to be within IIS 7 is to use the All Unassigned and then use the Host Headers field to direct the target traffic to that IIS 7 site. We were just expecting to see the shared cluster IP address(es) as an option to bind to from within IIS 7 along with the unique, dedicated host IP address ...
Any further guidance on this would be appreciated,
