I have BizTalk 2006 standard edition. I have it installed and configured on computer1. I then installed it on computer2. I want this instance to join the group created on computer1 so that I can create host instances on computer2. When I configured SSO, I selected "Join an exiting SSO System". When I get to the configure group section of the configure tool, after I select "Enable BizTalk Server Group on this computer", the radio button "Join an exiting BizTalk Group is grayed out. What am I doing wrong? Do I need enterprise edition to do this? Do I need a cluster? The doc implied that I don't need a cluster.
