Hi I cannot help you with Novell as I have never Administered it only Windows.
Q 2. "We all know that no matter how many times you request staff to keep all antivirus and patches up to date and not to click on any attachment whose source is doubtful they will continue to disregard this advice"
A good Internet policy for staff should be in place, then every member of staff should have no excuse for not implementing your procedures. If you haven't already got a policy in place, e-mail me and I can send you one that you can adapt to your working environment.
