Lost Local Area Network connection

I have a windows 2000 machine that is not talking to the local area network.
I have had the problem once before and corrected it by reinstalling Windows
2000 (complete overwrite).

The local area network uses TCP/IP protocol with all setting set to default.
The connection appears to be working but is not receiving packages. The
Local area connection status is enabled and shows a connect speed of 100
mbs. The hub sees the machine and the network card sees the hub.

Any Ideas?
 
As the physical connection seems to be ok, you could try
some basic tcp/ip troubleshooting, but you need to find
out more details to do something useful. The default
settings for a tcp/ip connection is to use a DHCP server
to get the IP address, find out the range of ip addresses
being handed down by the dhcp server on your subnet and
the address of some hosts in this subnet. Use ipconfig
from the command prompt to find out if you are getting an
address in the correct range, if the address is in the
169.254.x.x the dhcp server could no be reached, if it is
0.0.0.0 there is an assignment problem. You can try using
a static address on the same subnet and pinging host that
you know it´s alive, if there is no response there could
actually be a physical problem on the net card, maybe a
resource conflict, if it´s a plug & play card, try
uninstalling it and restart the machine for it to be
reinstalled, if it´s an old card, make sure the card´s
settings match the windows settings. If everything´s ok,
try using another card.
These are very general sugestions given in a very hasty
fashion, I hope they help you somehow.
