I recently set up a Windows 2003 Terminal Services Server to run Autocad 2005 on our network. Well, when I get two clients using it, and another person attempts to open the program, they are prompted with, " Only two instances of AutoCAD allowed to run in a terminal server environment." If I try to open the program locally when two people are using the terminal remotely, I get the same error. The program maker, says we are already in violation of our agreement by having more than one instance open. I need to get this to work. I will deal with the licensing later. Does anyone know of a solution? Registry hack maybe?
