prevent 2003 console session from auto log off

Hello
I need a little help. I have a 2003 SBS that is at a remote site. I need an application to run in at all times so I establish a terminal session with the console switch(the server does not have a monitor connected). Then I just disconnect the session instead of logging off. I do this so that the app will continue to run. I think that the server is doing some kind of auto log off with the console session. Is this possible? If so how can I disable this?
Thanks in advance.

 

If you login to the console via RDP then the actual console will lockout.
