It's easier to configure if the NLB matches the external domain, but it really doesn't matter.
But I would recommend you name the RPCCAA the same as the external OWA domain. [Definitive guidance is expected Real Soon Now. The "truth" is that there are several workable configurations.] Regards, Michael B.

I'm seeing conflicting info about naming & was hoping the experts here would chime in & help us out. The name of the NLB cluster - should it be the same as the name we give end-users to access OWA externally? Some folks are saying no, others are saying yes. As an example - nlb.ourdomain.local for the NLB cluster, and endusers use mail.ourdomain.com<http://mail.ourdomain.com> for owa. If we don't do that, will we need to add the nlb cluster name to our cert request? Is the only reason to use the same name for both to reduce the number of names (& therefore cost) on the cert request? Is the only reason to use different names to reduce troubleshooting confusion, if it becomes necessary? Thanks!
