I have seen a good article on CAS load balancing with Windows NLB. That is pretty straight forward and gives high availability for enterprises.
Now my question is, what all can be load balanced in CAS?
Am I wrong in understanding this? Because, I understood that outlook fetches the CAS server names from active directory when we try to do a automatic email configuration and my active directory is not aware of this windows NLB(or third party) implementation for CAS; so active directory simply returns the name of CAS server which is local to site.
