First I'd check with your network administrators to ensure there's nothing
wrong with the network and that they haven't put any bandwidth restrictions
in place.

I think what you're trying to do is \\REMOTECOMPUTER\c$ to access the C
drive on the remote machine.

My very first thought when I read that was "revision control system."
http://en.wikipedia.org/wiki/Revision_control
Depending on the RCS you use, that would allow users to have their own local
copies that they can keep synchronized with the master "one copy of all
files in the same location." It will also help manage multiple users making
modifications to those files simultaneously, and ensure that if any
modifications should happen to break those files you could reverse the
changes.
MATLAB even supports interacting directly with some source control systems
from within MATLAB, so you may not need to switch to a different application
to manage the files.
