First off, have you check your log files?  Look in both the fedora logs
as well as the event viewer in w2k.  Either might give you a clue of
what the problem is.

Next, try to isolate your problem.

1)Can your w2k communicate successfully with your fedora machine?  Try
transferring a large file between machines.  

2)If you connect your w2k machine directly to the Internet, can it
download pages successfully?

Verify your settings:
1)Do you have a proxy server, such as squid, installed?

2) check your tcp/ip settings in w2k.  

3) check your internet options in IE.

Remove your firewall to make sure it isn't causing the problem (though
messages should be showing up in the log if it is.)  Don't leave
yourself unprotected for more than a few minutes. 

Use at packet sniffing tool such as ethereal to determine what is
causing the problem.
