I've got a very strange setup that I'm working on. I've got a doctor's office running a practice management software on Server 2008 R2, which is also running Remote Desktop Services for remote users. This server is a member server. The domain controller is running Server 2003 R2. I know this is not a best practices situation, but due to software manufacturer restrictions, we are unable to promote the Server 2008 R2 machine to a DC or PDC. The Server 2003 R2 machine is also running Terminal Services. I would like to set up both servers to disable the shutdown button when users are logged on remotely. What would be the best way to go about doing this?
