Can't find anyone on the entire Internet to race with? Don't despair! You can fly the Acceleration multiplayer racing missions alone, against the clock. Simply host a multiplayer session (preferably via a LAN) without any other players and fly the race. There won’t be any other aircraft in the competition, but as a result, you’ll always win! It's a great way to learn a course, or to compete against your own best times.

To fly a multiplayer race by yourself:

1. On the main menu, click Multiplayer.
2. Under Connection options, select LAN and enter a Player name.
3. Click Sign In.
4. Click Host a Session.
5. Under Session Type, select Mission.
6. Click Next.
7. Select the multiplayer racing mission you want to fly.
8. Read the briefing, make sure the mission is still selected in the list, then click Next.
9. On the Host Options screen, select the number of laps you want to fly in the race, then click Next.
10. Change your aircraft if desired (click Change Role or Aircraft), then click Fly Now to start the race.

For more details, see the "Hosting a Multiplayer Session" article in the Flight Simulator X Learning Center.

If you know the people you’re going to fly with, everyone can connect directly to the host's computer (instead of using Gamespy).

The host must first tell everyone his or her IP address. An IP address identifies a computer that is connected to the Internet or a network. An IP address usually consists of four groups of numbers separated by periods, such as 192.200.44.69.

To find your computer's IP address:

1. Click Start.
2. Click Run.
3. In the text box, type cmd.
4. Click OK.
5. In the command window, type ipconfig.
6. Press Enter.

Your computer's IP address and associated information will be displayed. The IP address will be displayed in the line labeled "IP Address" (Windows XP) or "IPV4 IP Address" (Windows Vista).

Once the host knows his IP address, he can share it (via email, chat, or telephone) with the other session participants. They can then use it to connect directly to the host's computer.

1. On the main menu, click Multiplayer.

If you don't have time to complete a Mission, you can save it in progress and fly the rest of it later. On the Flights menu, click Save. Type a title and description, and click OK.

You can find your saved mission on the main Missions screen by selecting the Show saved Missions check box.
