I have multiple clients running Windows XP with a Novell Client installed. Users lock their computer when they are away from their system. After they enter their credentials to log back in, the computer proceeds to shut down. The computer also tends to freeze on the "Saving your settings" portion of the shut down. After the Novell client was removed this problem did not happen again. Unfortunetely I cannot remove the Novell client from everyone. Any thoughts on how to prevent this auto shut down?
