having small issues with new cable internet service

[philip485]

I have 3 computers on a network at my house. They share an internet connection through this computer, a P3 800 mhz win 2000 pro machine. Its been recently reformated and cleaned up and performs like a champ. The cable service I am using operates by downloading through cable, but uploads through a telephone line. There is one file that I have been using to test speeds as well as speed tests. For some reason, the client computers download and upload almost 5 times as fast as the host. There are no programs running or any p2p programs so I cant figure out why its doing this. Is there a way to configure this setup? It cant be hardware since the other 2 computers connected have no problems. One is a celeron laptop and the other is a P4 1 ghz laptop. The P4 downloads almost 260kbs and runs winxp. The other laptop runs 2000 pro and downloads 100kbs and this machine here running 2000 pro only downloads at around 50kbs. Anyone have any ideas?
Thanks,
Philip
