We are using NLB, and the VIP is say: webmail.abc.com = 184.108.40.206
CAS01 = 220.127.116.11
CAS02 = 18.104.22.168
All the above is in DNS with MX records
My concern is when we reboot CAS02, OWA goes down, isn't NLB supposed to be if CAS02 goes down CAS01 takes over or if CAS01 does down CAS02 takes over.
That is not the case for us, can anyone give me a suggestion on what I have to check to see if everything is configured correctly.
