Clogged bandwidth

3 computers networked through a hub. All components tested and working
flawlessly. The 'main' computer (closest to hub, etc.) is experiencing very
slow 'download' speeds, however 'uploads' are approx. twice as fast (i.e.
down - 370 kbps / up - 699 kbps). The other two computers are achieving
excellent down/up speeds (1600 - 1900kbps / 700 kbps). The 'problem' machine
appears to be in great shape - no viruses, latest software/patches/Service
packs, etc. and otherwise, functions just fine (Thinkpad A22 P III - 800 -
Win 2K). ISP cannot determine any issues from their end. Machine is pingable
and all other applications/components are working without a problem. Any
ideas as to what might be "clogging" up the bandwidth? Logic points to a
problem with the actual computer, however, there is no evidence of anything
being wrong. Any suggestions will be appreciated.

Did you try updating the NIC driver and replacing the cable?

You'd be surprised how many problems are caused just by bad network cables.

You might have been exploited to run as an open mail relay. Drop to a DOS
command prompt and type
netstat -a
This will show you what connections have been made to and from your
computer. If you see lots of connections to misc computers on the internet,
you probably have a virus. Hard to say without any more detail.

Good luck.
