We're running a Windows 2003 Termnial server and use it as an application server. All users connect to the server using Remote Desktop and they're connected the whole day. Every once in a while, we need to tell them to get out of the program they're running because we needed to make some maintenance or change a file on their program, etc, and we needed everybody to be out or logout of the termnial server in order for us to do the maintenance. But they don't wait for our call to let them know they could get in or not, and this is very annoying because it could corrupt the data or files in the program we're working on. Is there a way to stop them from running the program they're running or jsut to stop Remote desktop from the server so they can't log in until we tell them to?
