I'm sure this must be a really easy one.. but Google has let me down... I'm after a document/website that describes what the various IMA Subsystems are and their function.. e,g, distribution subsystem is responsible for transferring files to other subsystems. Nothing in either the XP admin guide or advanced concepts for XP. Anyone know where I can find this ?
