• Recommend Restarting Windows Server to save the new settings after applying Exchange 2003 SP2. Also recommend backing-up the installation or entire O/S. It may be easier to use something like Bart's X-PE to boot your server, and use Ghost 9 to backup an image (or images of each) installation and data partition, saving those partition images into a pre-named folder on an attached external USB drive. You can restore from there if you later have a problem with configurations after installing Exchange 2003 SP2. This is only recommended before configuring exchange mail boxes or before using ExMerge to restore mailbox data from a retiring Exchange Server.
