v1a has a very minor update to the nslookup commands.

Here are errors I've seen with Event Broker 2.21 (Installer 1.50.9) when an internal or external dns server is setup that cannot forward/reverse lookup based on hostname/fqdn/ip. For every node in the cluster, please check /etc/resolv.conf and make sure you can forward/reverse lookup for every server listed. Use the syntax of "nslookup [name] [server]" to check every entry in /etc/resolv.conf. For example, "nslookup eb1.example.com 192.168.0.53" is used to query the 192.168.0.53 DNS server for the entry eb1.example.com.
