How do you mean what server does it go on? GameCP have some sort of documentation and FAQ at http://gamecp.com/
If you're after getting help from other users then I suggest to look at there forums. There ought to be some threads there that can help you.
By which server does it go on, I meant whether it goes on my web hosting server or one of my dedicated servers which run the games.
I've got the same question. I think they should have a module where you must have to enter your game server login / administrator details. Right?
