Allow terminal services users to run program as administrator

Hi

I'm trying to resolve a problem with running Sage 2009 and 2010 in terminal services mode on Windows Server 2008. Users log on via remote desktop connection, and we have a group policy set up to load the software and a seperate logon script that runs in order to copy a file to a working directory to point the program at the correct data set.

I'm getting an intermittent error which Sage informs me is because I need to allow users to run Sage with administrative privileges. They advise I do this by ticking the "run this program as an administrator" tickbox in the compatibility tab when going to the properties on the .exe file, and to do this as well in the settings for all users.

The problem I'm getting is that as soon as I tick the box for all users, then try to log on as a user, the system gets to the point where Sage should load, then it instantly logs me off without any further input. I desperately need to get this working, does anyone know why this would happen? Is it something in the group policy or local policy settings that's causing the instant logoff?

Thanks
