I was asked this question by a customer today. Where are the templates for Exchange 2010? Answer: We don’t have any. Exchange 2010 was shipped secure by default. The SCW templates that we delivered in Exchange 2007 didn’t do anything to the application but to ensure that all required services and firewall rules are set. No other application settings were made. SCW can still be used to harden the OS but no rules for the Exchange application are needed.
Of course utilizing the great pre-requisite scripts has been very helpful in prepping my Exchange 2010 deployments. These XML scripts make installation very simple. http://technet.microsoft.com/en-us/library/bb691354.aspx
