After you’ve configured installation settings on a network installation point using OCT and the Config.xml file, you can distribute the customized install to users in the field via DVD. Simply copy all the files and folders from the network installation point to DVD, including any .msp files you’ve saved to the Updates folder and your modified Config.xml file.
Users can then run Setup.exe from the DVD and get the same customizations as users installing Office 2010 from the network installation point.
Note that the simplest method relies on the modified Config.xml file being stored in the same folder as Setup.exe. If you stored the new Config.xml file elsewhere, the user will need to use the /config switch to specify where the file is stored. For example, if the disc is in drive D:, the command might look something like this:
D:\Office2010\setup.exe /config D:\DifferentFolder\Config.xml
