Depending on whether your BizTalk environment is multiple-server or stand-alone environment, you can use domain users or local users. If you have a multiple-server configuration, then you must use domain groups and domain accounts. BizTalk Server supports local groups and user accounts only in single-server (standalone) configuration. In this example I will talk about a multiple computer configuration. For more information about which groups are necessary in BizTalk and how to create them, follow this link: http://msdn.microsoft.com/en-us/library/aa577661.aspx

The MessageBoxViewer MBV is one of the main tools we have at hand to manage and monitor our BizTalk environments. This tool has been created by Jean-Pierre Auconie, and is currently available in version 11.

First of all, keep this in mind: "If for any reason your BizTalk Environment has to be restored, or there is a massive change that messed up your SSO and you do not have a backup of the Master Secret Key you will have a problem."

So why this warning?
