Exchange 2010 SP1
We created one CAS array which includes CAS1 and CAS2 by following this linkhttp://www.kraftkennedy.com/blog/bid/102109/Configuring-NLB-for-Exchange-2010-CAS-Load-Balancing (one NLB NIC and one Public NIC. these two CAS servers are VMware VM servers. The cluster mode is unicast. Here are rules
today, about half of my company users lost outlook connections and they can not access OWA either.
I ended up: remove CAS2 from NLB cluster; change cas array IP to CAS1 IP. users are back online.
Can anyone help me to resolve this?
Thank you.
