Have you looked in the Citrix Knowledge Base ? I did a search for IMA Subsystems and found this as a starter..Not quite what you are after.. but if you dig deeper it might be there. http://knowledgebase.citrix.com/kb/entry!default.jspa?categoryID=3D118&entr= yID =3D2343&fromSearchPage=3Dtrue Watch out for the dreaded 3D freelist additions in the link above Dave=20 -----Original Message----- =20 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 ?
