When i configure my CAS array, the FQDN for the CAS array name will be "outlook.mydomain.com" and this name will point to the vip on the wnlb cluster. We have a split DNS setup, we have an internal and external DNS zone called "mydomain.com" I know i need to create the A record for outlook.mydomain.com in my internal DNS, but do i also have to create an A record for outlook.mydomain.com in my external dns zone?
and lastly i have two 2010 CAS severs that are running on windows 2008 sp2 and configured using wnlb. The vip ip for the wnlb array in internal dns points to outlook.mydomain.com, and this is working fine. All of my exchange web services and OWA point to https://mail.mydomain.com/autodiscover/autodiscover.xml ect,ect,ect I want to load balance any request comming to mail.mydomain.com across the two CAS2010 servers as well. Can i use the same ip address that the wnlb cluster is using for outlook.mydomain.com as well as mail.mydomain.com ? so in internal DNS i would point (for exmaple) 10.7.13.2 to outlook.mydomain.com and then create another dns record for mail.mydomain.com that also maps to 10.7.13.2 ? This way i dont need to add another ip address to the cluster nic
