The normal thing is to use Office 2003 Resource Kit to creat unattended.mst file and call it when installing office2003,
I've tried to creat many .mst file for each application in office 2003, i.e. word.mst, Excel.mst, ...etc and when doing this with ORK2003 I've choosed the application I want only, so now we have a single .mst file for each application in office 2003 (Word, Excel, PowerPoint, Access, Publisher, InfoPath, and OutLook)
and when choosing the components, I choosed the application I want (run all from my computer or what ever you want to choose) plus the last two components in the tree, so with every application I've choosed the three components, and choosed not avaliable for the rest, then finish the file creation normal, then done.
