User having problem with mac remembering settings

I work on a PC but I have mac users in my office, and with the head tech guy on vacation i (a programmer) have to support everyone.


A user has it set up so that has a roming profile, (i'm assuming the profile is held on one of our g4s that are acting as a server).

He also has an external maxter hard drive (I think connected through firewire 800) and in Ilistrator its set as his primary hard drive.
(Illistrator -->preferences --> plug in scratch drive) This setting should be set to the external hard drive, but it always keeps going back to the primary hard drive.

any clue whats going on?

 

yes, the external hard drive, has never been unplugged. and I doubt it was ever unmounted either.
