Fast transfers between networked computers?

I have a high speed router and two computers running off of it. I know that there's a way of getting them to be able to transfer files through the router at the router's top speed and just bypassing the internet connection but I haven't figured out a full-proof strategy. When I use yahoo messenger, it works sometimes. But only maybe 1/4 times. Is there some program I can get somewhere that's made to transfer files from computer to computer along the same network?

Hmm. A little hard to answer concisely. I'm assuming that you are running Windows. You need to set up file sharing on both computers. Run the Network Setup Wizard on both machines. Then select some folder, say My Documents, and enable it for sharing by right clicking, selecting Properties and going to the sharing tab. You can make a folder read-only or read-write depending on your desires/needs. Do this on both computers.

Then you can use "My Network Places" to find one machine from the other. At that point you just drag-n-drop files between the two machines.

I know this is kinda sketchy. You should try searching on this YahooAnswers site for answers on setting up home networks. I know I've seen this question exhaustively answered.
