Exchange 2007 includes two registration files for SCW. The general Exchange 2007 registration file is called Exchange2007.xml. It defines the security configuration for all Microsoft Exchange server roles, except the Edge Transport server role. The registration file for the Edge Transport server role is called Exchange2007Edge.xml. It defines the security configuration for Edge Transport servers.
The registration files are installed in the %Programfiles%\Microsoft\Exchange Server\Scripts directory when you install Exchange 2007.
Services that are enabled set the service startup value to either Automatic or Manual.
Ports that are enabled specify executable files (.exe) that are trusted by Windows Firewall to open ports for the specific application.
The Exchange 2007 registration files that are used by the SCW specify the port executables according to their default location. In most cases, the default location is at %Programfiles%\Microsoft\Exchange Server\bin. If you have installed Exchange into a different location, you must edit the <Path> value in the <Port> section of the Exchange 2007 registration files to indicate the correct installed location.
