I have a strange issue with a 2003 server where when I Remote Desktop into the machine I don't see the console being locked up. It used to lock up and take over the console's session but not anymore. It seems that both RD user and console user is having the ability to run their own session as in Terminal Service.
The 2003 server is not a terminal server and was never configured as terminal server.
Is there a way I can disable this or how to troubleshoot this?
