------------------
Our system is starting its 3rd year and runs Windows 2000, but it sounds 
like a similar setup. However, we do not have individual authentication 
for the students and instructor. It is true that the Divace Duos do not 
function if they can't detect the ICM.
However, the shutting and closing of the Divaces, or the restarting of 
individual computers, should not affect the functioning of the ICM. It 
certainly doesn't in our lab.

If the system is used for drop-in labs or other use, then probably you 
should have an administrator log in to the instructor computer in the 
morning and leave it on all day so that the ICM is not closed.
If your system is used only for classroom use, you could just have the 
instructor restart the student computers before he/she logs out--that 
might maintain the connectivity between ICM and the student computers. 
IE, the ICM is always turned off after the student computers, and 
restarted before they come back on.

Have you contacted your rep, or Nils Soderberg of Tandberg, who is their 
national tech guru? They can't always wave a magic wand (too many 
different kinds of installations) but the problem you describe re. the 
ICM losing contact with the student computers seems like something they 
would recognize.
