Hi Sorin, This was a problem which I identified when I did a security audit of one of my schools. I did post the problems we were having with certain students trying to hack into the system. One of ths issues was using other users login details to get on. Now we want to restrict login to 1 session for the kids, and my understanding is that you can set up different policies for different groups of users, if that is the case we will be exploring that options as well, but we'll see. Thanks Patrick ________________________________ From: Sorin Srbu <sorin.srbu@xxxxxxxxxxxxx> To: windows2000@xxxxxxxxxxxxx Sent: Wednesday, April 22, 2009 8:16:31 AM Subject: [windows2000] Re: how to prevent user from logging in more than once - windows 2003 Any particular reason you want this? I for one am logged on on several different places and would find it awkward to be forced to log off on machine in order to logon to another. -- /Sorin >-----Original Message----- >From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000- >bounce@xxxxxxxxxxxxx] On Behalf Of Patrick >Sent: Tuesday, April 21, 2009 1:01 PM >To: windows2000@xxxxxxxxxxxxx >Subject: [windows2000] how to prevent user from logging in more than once - >windows 2003 > >Hi guys, > >I knew this was pretty straightforward with NT4.0, but is there a way to achieve this >on windows 2003 without a 3rd party tool.
