While the unwashed console masses are quite content with their peer-hosted multiplayer games, the PC master-race still foam at the mouth if they don't get sweet dedicated server love. While the dedicated server implementation in the freshly-launched Call of Duty: Modern Warfare 3 isn't ideal (in the supposed interests of leaderboard integrity and security, only peer-hosted games contribute to your player rank and statistics), the option of running your own standalone server is at least present.
If you have the hardware and bandwith and you'd like to get your very own server up and running, MW3 co-developer Sledgehammer Games have posted up a starter guide
describing the basic setup and explaining some of the features you can tweak.
