Can you check if you can access files in computers in these directions: Ultimate -> XP, Starter -> XP, XP -> Ultimate, XP -> Starter? Take screenshot of Network (where you can see all computers) from laptop with Ultimate, then get into this PC (or \\Ultimate-PC-Name\ ) and take a screenshot. Make a test directory on Desktop, make or copy some file into it and share this folder: Properties -> Sharing -> Advanced sharing -> mark Share this folder -> Permissions -> mark Read, Write and Full Control to Allow. Accept all windows and check if is it folder visible from XP and Starter.
Do the same on computer with 7 Starter (make and share folder) and check from XP and Ultimate. Write what has gone succeed and what hasn't.
