  • Question on CAS vs load balancer

    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?

    OWA
    Outlook Anywhere
    AnctiveSync

    But not...

    Auto discovery

    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.

    Thanks,

    Re: Question on CAS vs load balancer

    I got my answer. I understood that though autodiscover service can be load balanced we are not adding much value to it as built-in functionality itself is providing more availability. I documented my learning at my blog(http://www.sitaram-pamarthi.com/2009...y-its-cas.html) which explains how the autodiscover service is load balanced.
