Terminal Services only allows two instances of an application

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?

You should have the Network licensed version - it's optimized for multiple users.  The stand-alone copy is a different executable.  I'm afraid that Autodesk is not feeding you propaganda here.

You have hit your licensing limit with Autocad.  I just went through a similiar situation and was on the phone with their tech support for hours.  As Netman said, they are not feeding you propaganda here.  You need more licenses.

Well, that's what I was afraid of!  But, why does the program allow two instances, not one?  Are we sure there's not a hack for this?

It's all about file locks.

No, I wouldn't think there is a hack since the executable is where the locks come into play.

Since this is expensive stuff, you should be certain you need all these simultaneous connections before moving on this.

Thanks people.  I thought we were going to get the programmers involved, that's why I offered so many points.  Netman was first, so I gave him the largest portion.

Thanks again,
