If you haven't already bought the Exchange and Windows licence, that is well over the cost of a load balancer. You can also go free with Zen Load Balancer. <br />

WNLB causes a lot of problems, which is why the Exchange product team does not recommend its use. <br />

I have about 200 user on Exchange 2010. &nbsp;I have one CAS box. &nbsp;I want to install new CAS server and setup CAS array. &nbsp;I understand I need to install NLB on both of my CAS servers. &nbsp;My question are:<br />
<br />
1- Will I need to reboot my current CAS server?<br />
2- is there a down time expected?<br />
3- How should I plan this so it has minimal impact to users?<br />
4- How should I roll out the new CAS array after I built it to all Outlook users?<br />
<br />
Thanks
