The wizard uses the engine from the Microsoft Exchange Best Practices Analyzer Tool to check the prerequisites. This engine gathers information about your server and your organization, and then evaluates that information against a set of rules. The rules are stored in the ExBPA.PreReqs.xml file, which is located in the Setup\ServerRoles\Common\<language> directory. If the server can access the Internet, Setup will check for a more recent version of the prerequisites file than the one that is located in the Setup\ServerRoles\Common\<language> directory. If the server cannot access the Internet, or if there is not a more recent file available, Setup will use the local prerequisites file.
