Building a new BizTalk 2013r2 VM for the first time today and I ran into a problem that I guess may hit a few people.When I started the ESB Configuration tool I received the message "Object reference not set to instance of an object". It turns out the tool relies on some on some of the IIS6 management tools. Once I'd added these from Server Manager I restarted the config tool and it worked ok.
