Ken,

Thanks for your reply.
Jimmy Snowden replied me with the tweak described at at:

http://www.tweakxp.com/tweakxp/display.asp?id=282


The problem is this tweak is for XP and cannot figure out how to
replicate in Win2k: I do not find the QoS Packet Scheduler inside the
Network section at the step #7.

About your suggestion I don't want to realize a 'traffic shaping' but a
fixed 'bandwidth shaping' at 9600 or 14400 bps. So the third PC should
never be able to access faster to that speed/bandwidth even if the other
two PCs does not use any of the full available bandwidth the Router
could offer.
I suspect, but maybe I'm wrong, the solution should be done not with a
'prioritation' of the use of the bandwidth - that eventually will allow
variable access to the bandwidth - but with a fixed % of the Bandwidth.
Unfortunately this is not explaned in the Tables 11-1/11-2 , page 11-4 
of the 'IP Routing Policy' chapter in the router's manual.

Essentially the third PC should be connected to the net as with an old
9600 bps modem.....

Any other idea?

Thanks again,
Albert
