Game server hosting?

I've been coding an online RPG for a while now, and I've tested it with multiple local clients on my PC, and 1 other remote client (50 client max for now). I'm on a 28.8 connection (all there is in my extremely rural farming area) and I was wondering if there are services available that will host Windows based game servers? A service that will allow me to login remotely and operate, shut-down, update, etc... the program. This way I won't have to trust and rely on an indivual cable/dsl user to maintain the server.

Thanks!
