windows 2003 internet connection sharing consume lots of cpu

[Guest ljh131]

i use my server (cpu: p3 866) for routing my home network.

 

(wan speed is almost 100mpbs up/down)

 

when i download some files through my router server, cpu usage of

server up to nearly 100%. fortunately, download speed is not so bad.

 

but up speed is very slow (below then 10mbps). and it does not consume

lots of cpu power.

 

if someone know this problem, please reply.
