Hello "John"<br><br>I run Deep Freeze Enterprise here at our regional office and help a number of libraries implement it as well. I'm not sure what CASSIE does that DF does not. But, you can configure DF to reboot after a customizable amount of idol time. It will even notify the patron before rebooting if they are "using" the PC but have not been seen as active for the prescribed time.<br>
<br>And, DITTO to all the other features of DF that Mohamed mentioned earlier. The enterprise version of DF is the only way to go in my book.<br><br>Bill<br><br>Bill Hardison<br>Computer Services Coordinator<br>Northwest Regional Library System (NORWELD)<br>

<p><span style="font-size: 10pt; font-family: Arial; color: black;">Right
now our public computers are locked down so that you can't install anything,
can't run anything that's not on our run-only list, etc. This of course
is in order to keep each computer from getting messed up for subsequent
patrons, and to protect other machines on the network. Of course, there
are times when the computers won't do something a patron wants to do, like
using a web site that requires its own special software to be installed or
running a program from a CD-ROM for school. </span></p>
<p><span style="font-size: 10pt; font-family: Arial; color: black;">So,
we're going to try switching to a less-locked-down setup. We're going to
use Deep Freeze to restore computers when they reboot, and we're going to use
CASSIE to reboot between patrons. (Both of these programs are new to us.)
I would appreciate any suggestions for further measures to take to keep
things secure and running nicely. Our environment: We have 34 public PC's
which we're replacing with new ones (with Windows XP); we have an
Active-Directory-enabled Windows domain with one DC, runningServer 2003. </span></p>
<p><span style="font-size: 10pt; font-family: Arial; color: black;">My
ideas are to have one user account per computer (with permissions only to that
computer) as a local power user, to put these computers on a separate subnet
and if possible a VLAN, and to make sure our Windows server is locked down as
much as possible. I could put them on a separate segment of the firewall,
but I understand that you can't manage a Windows domain through a firewall (or
any other kind of router) and it seems like it would be useful to manage these
computers on our existing domain. I don't yet know how we can keep users
from turning off CASSIE after they log in; I'm not sure if keeping them from
running taskmgr.exe will do it; if nothing else I suppose we can have a script
run every minute or 5 minutes, check for the CASSIE process, and reboot if it's
not running (I think I can make this invisible to the user using a VBS instead
of just a BAT file). </span></p>
<p><span style="font-size: 10pt; font-family: Arial; color: black;">Thanks
for any help you can give me, even if it's just thoughts, or reasons you think
this is a bad idea. If you reply privately I won't forward your info to
anyone - I know you might not want to talk publicly about your security.</span></p>
